The cretaceous-tertiary mass extinction was apparently caused by a meteorite that struck Yucatan Peninsule in Mexico
Answer:
The "cretaceous-tertiary" mass extinction was apparently caused by a "meteorite" that struck the Yucatan Peninsula.
Explanation:
The Yucatan Peninsula lies between the present-day 'Gulf of Mexico' and the 'Carribean Sea'. The meteorite that struck this peninsula about '66' million years ago was '10 to 15 kilometers' wide in size. A huge crater was formed after the meteorite hit the Earth at the Yucatan Peninsula. This crater in today's date is known as the "Chicxulub impact crater".Greek island where a famous armless statue was found

An important property of air circulation is
a. warm air is denser than cold air.
b. cold air and warm air have the same density.
c. cold air is denser than warm air.
d. air has no mass.
the answer should be c.
because heat rises meaning hot air is less dense than cold air
Final answer:
The correct answer is 'c. cold air is denser than warm air,' which is essential in understanding atmospheric phenomena such as convection currents, where warm air rises due to decreased density and cold air sinks.
Explanation:
The correct answer to the question about an important property of air circulation is c. cold air is denser than warm air. This concept is fundamental in understanding atmospheric behavior and the principles of convection. When air is heated, its particles move more rapidly, causing it to expand and become less dense. This decrease in density leads to buoyancy, as warm air rises because it is less dense than surrounding cooler air. An example of this phenomenon is the operation of a hot air balloon, which ascends when the air inside the balloon is heated and consequently becomes less dense.
In contrast, cold air is denser, meaning that its particles are more closely packed together and it has a higher mass per unit volume compared to warm air. This explains why cold air tends to sink and why warm air rises, creating convection currents. These currents transfer thermal energy and play a significant role in weather patterns and global climate.

Currently the Juan de Fuca plate is interacting with the North American plate where inland volcanoes and deep focus earthquakes are occurring. What type of plate boundary is this? View Available Hint(s) Hint 1. opened hint The Juan de Fuca plate carries predominantly oceanic crust, while the North American plate has an abundance of continental crust. What type of interaction between oceanic and continental plates is associated with volcanic activity? Currently the Juan de Fuca plate is interacting with the North American plate where inland volcanoes and deep focus earthquakes are occurring. What type of plate boundary is this? a continental rift zone a divergent plate boundary a mantle plume a transform boundary a convergent plate boundary
The correct answer is - a convergent boundary.
The Juan de Fuca plate is one of the smallest plates on the planet. It hasn't always been that way though, as in the geologic past this plate has been very large. As the time passed though, this plate started to subduct under the North American plate, in fact most of it is already subducted. In he present, this plate is subducting in the northwestern part of the North American plate, it is fragmented into three smaller pieces, and even though the name officially still goes for all of them as a whole, very often the name is used just for the central part of it.
The convergent plate boundary and the subduction as a result of it, has caused the formation of mountain ranges along the western side of the North American continent, between southern British Columbia and the northern part of California.

What city state was located on Peloponnese?
The city state located on Peloponnese was Sparta.
Sparta was the only city state located on the southernmost part of Greece, on Peloponnese. It is one of the two best known city states along side Athens, and it was always one of the two strongest ancient Hellenic city-states.
Sparta though was not like the other city-states of the Hellenic world. While all others were developing some form of partial democracy, where orientated toward trade, science, Sparta was the total opposite. Sparta was ruled by a monarch. All the healthy boys were trained to serve the military and that was their only job in their lives. Most of the hard work was done by slaves. The women had role in the household but also the same rights as the men. The society was mostly striding toward self-sustaining, resembling and ancient type of socialism in a way.
Sparta was the city-state located on Peloponnese. It was the most powerful state in that region during the late sixth century BCE, due to its agricultural wealth and its effective organization of the city-states into what is known as the Peloponnesian League.
Explanation:The city state that was located on Peloponnese as referred to in your question was Sparta. By the late sixth century BCE, Sparta had emerged as the most powerful state in the Peloponnese due to the wealth they gained from the rich agricultural land that they controlled.
Sparta also organized the city-states of this region and parts beyond into a system of alliances referred to as the Peloponnesian League. While each city-state in the league maintained its self-governance and did not pay tribute to Sparta, they were expected to align politically with Sparta.
Sparta's army also played a role in maintaining its dominance by overthrowing tyrants in the Peloponnesian city-states and restoring political power to the aristoi.

The equilibrium price for T-shirts is _____. $5 $10 $25
The equilibrium price for T-shirts is determined by the interaction of demand and supply in the market.
Explanation:The equilibrium price for T-shirts is the price at which the quantity demanded by consumers is equal to the quantity supplied by producers. In this case, the question does not provide enough information to determine the equilibrium price. The options given are $5, $10, and $25, but without knowing the demand and supply conditions, we cannot determine the specific equilibrium price.
Equilibrium price is determined through the interaction of demand and supply in a market. If the demand for T-shirts is high and the supply is low, the equilibrium price may be higher. On the other hand, if the demand is low and the supply is high, the equilibrium price may be lower.
Therefore, without additional information about the demand and supply for T-shirts, we cannot determine the exact equilibrium price.
Look at the diagram below.
The picture shows Earth on the left and the sun on the right. The axis of Earth is shown tilted with the north pole towards the right and south pole towards the left.
New York is located in the northern hemisphere. Based on the diagram, what was the season in New York six months ago? (2 points)
summer
winter
spring
autumn
Answer:
Winter
Explanation:
The picture shows the position of the Earth compared to the Sun around the June solstice, when the North Pole is closer to the Sun than the South one, that's Summer in the Northern Hemisphere.
Six months ago, the situation would be reversed... and then the Southern Pole would be closer to the Sun... and it would be Summer again, but in the Southern Hemisphere, and Winter in the Northern Hemisphere.
The question could have been six months in the future, with the same answer, since an orbit around the Sun takes a year.
Six months ago, it was winter in New York because the Earth’s Northern Hemisphere was tilted away from the Sun.
The picture shows Earth with its axis tilted, indicating the seasons due to the Earth's tilt and orbit around the Sun.
Since the Northern Hemisphere (where New York is located) is tilted towards the Sun, it is currently summer in New York. Given that seasons are approximately three months long, six months ago, it would have been winter in New York.This is because the Southern Hemisphere would have been tilted towards the Sun, experiencing summer. Therefore, the Northern Hemisphere would have leaned away from the Sun and experienced winter.Thus, it was winter in New York because the Earth’s Northern Hemisphere was tilted away from the Sun.
Dinosaurs once stomped across much of the planet, sometimes leaving tracks in mud that were buried in more mud and later hardened to stone. this sample is from the philmont scout ranch in new mexico. it is a loose block that fell down from a cliff above. the footprint was made by a tyrannosaurus rex. the print is 33 inches long (almost 3 feet for one foot!) and 28 inches wide, and extended 9 inches deep into the sediment. the sun was shining as indicated, and the black arrows point to shadows from two of the three toes of the track. is the rock with the track now upside-down (you are looking at the side that was down when the sediment was soft) or right-side up (you are looking at the side that was up when the sediment was soft)?
you are looking at the foot print of a t-rex. the reason it is soo deep is because the soil is soft and the t-res is so heavy it made it go down.
Answer:
In this case study: The rock with the track is upside-down.
Explanation:
All right this is going to be very difficult so please pay careful attention. First of all, prints are the impression a living thing leaves in soft terrain without consideration of its composition. The physics of the print is down displacement of the terrain by up-down pressure. In this case, after it mineralized the rock was built in the opposite. To fill the space left by the dinosaur. So instead of being an incision, it became a protrude. So if the shadows draw an extending mantle away from the edge of the print. That means it is a terrain protrude and that is upside down.

You are a geologist. While walking in the fog one day, you bang into a cliff. After rubbing your sore nose, you inspect the cliff, and see what is shown in the picture, in a one-foot-square area. You recognize that this cliff is made of “fossil sand dunes”, with wind-blown sand that was later glued together by hard-water deposits. You are accompanied by a student, who is carrying your tea and crumpets for you. You sketch four arrows on the cliff, label them as shown, and ask the student which of the arrows was pointing up when the loose sand was deposited. Your student is brilliant, and correctly tells you the answer. The arrow that was pointing up when the loose sand was deposited is the arrow that is closest to:
may be the way the wind blew? or that that is the way the sand is deposited
The arrow that was pointing 'up' when the loose sand was deposited would be the one that is opposite to the direction of tapering or thinning of sedimentary layers or opposite to the steep slope of the cross-bedding present in a fossil sand dune formation.
Explanation:When sedimentary rocks, particularly those originating from sand dunes, solidify, they retain the directional pattern of the wind flow during their formation. This directional pattern is often preserved in the form of inclined layering or cross-bedding. In this scenario the original 'up' direction when the sand was deposited can be determined by looking at the orientation of these layers.
When wind-blown sand settles down, it forms angled or inclined layers of deposition, with the inclination facing the direction the wind was blowing from and the opposite direction being 'up'. Therefore, observing the way these inclined planes are stacked would reveal the original 'up' direction.
For instance, if the student points to the arrow which is opposite to the direction of tapering or thinning of the layers or opposite to the steep slope of this cross-bedding, that would be the correct answer as this indicates the arrow that was pointing 'up' when the loose sand was deposited.

Placer deposits are formed by alluvial processes within rivers and streams, and on beaches. Placer gold deposits form via gravity, with the density of gold causing it to sink into trap sites within the river bed, or where water velocity drops, such as bends in rivers and behind boulders.
The geologic process results in formation of gold ore is called Forming Deposits.
Explanation:Gold occurs as the deposition in the fractured rocks called as the lodes. This process is commonly referred to as the forming deposits process.
When the heated hot fluids circulate through the gold bearing rocks then it picks the gold from it and sweeps it to new location by concentrating the gold elements. These concentrated loads or the gold ores are also called as the veins.

They are extra-high tides and extra-low tides.
They are caused when the Sun and the moon align and exert additional gravitational pull.
Explanation:
Tides are periodic movements of the great masses of water on our planet as part of the gravitational attraction exerted by the moon and the sun on Earth.
In this sense, there are two very special cases: The Spring and Neap tides.
Spring tides
Occur when there is a full moon or new moon, which makes the tides higher. During these lunar phases, the Moon, the Earth and the Sun are aligned and the gravitational attraction power is greater.
Neap tides
Occur when the moon, the earth and the sun form a right angle ([tex]90\º[/tex]), being the gravity attraction on the masses of water the minimum. This happens in the crescent and wanning phases.
Answer:
- They occur twice a day.
- They are extra-high tides and extra-low tides.
- They are caused when the Sun and the moon align and exert additional gravitational pull.
