The geologic crosscut with five layers represents different types of rocks formed under different atmospheric conditions. The limestone layers indicate a time of abundant marine life, the banded-iron formations suggest an oxygen-poor atmosphere, the metamorphic rocks indicate geologic activity, the red beds suggest the presence of oxygen, and the chert layers suggest unique atmospheric conditions.
Explanation:A: Limestone layers - Limestone is formed from the accumulation of marine organisms such as shells and coral. The presence of limestone indicates that this layer was once underwater, suggesting a period of marine deposition. This is relevant to the history of the earth’s atmosphere because it signifies a time when the atmosphere contained enough carbon dioxide to support the growth of marine life.B: Banded-iron formations - Banded-iron formations are sedimentary rocks that contain alternating layers of iron-rich minerals and silica. These formations are evidence of the Earth's early oceans and the iron-rich waters that existed at that time. The presence of banded-iron formations suggests that there was little to no free oxygen in the Earth's atmosphere during the deposition of these rocks.C: Metamorphic rocks with fine grains - Metamorphic rocks are formed from the transformation of existing rocks under intense heat and pressure. The presence of fine-grained metamorphic rocks suggests that they were subjected to high temperatures and pressures. This could be a result of tectonic activity, such as mountain-building events, which is relevant to the history of the earth's atmosphere because it indicates periods of geologic activity and the release of gases into the atmosphere.D: Red beds - Red beds are sedimentary rocks that contain a high concentration of iron oxide, giving them a reddish color. The presence of red beds suggests that the atmosphere had oxygen during the deposition of these rocks. The iron in the sediments oxidized in the presence of oxygen, causing them to turn red.E: Chert layers - Chert is a sedimentary rock composed of microcrystalline quartz. The presence of chert layers indicates that these deposits were formed in environments with a high silica content, such as deep ocean basins or hot springs. This is relevant to the history of the earth's atmosphere because it suggests the existence of specific environments with unique atmospheric conditions during the deposition of chert.Learn more about geologic cross-cut here:https://brainly.com/question/32797068

coastal areas that are near warm ocean currents are more likely to experience what type of weather
Coastal areas near warm ocean currents tend to experience milder temperatures and higher precipitation levels, influenced by the warming and rising of air, which leads to condensation and increased precipitation. These regions can also face a greater risk of extreme weather events, including more active hurricane seasons due to higher ocean surface temperatures.
Explanation:Coastal areas that are near warm ocean currents are more likely to experience milder temperatures and higher levels of precipitation. Warm ocean currents heat the air above the water, which causes the air to rise and cool, leading to the condensation of moisture and increased precipitation. This process can result in climates such as the humid subtropical climate, where moderate amounts of precipitation are observed most months of the year. Additionally, these areas typically have warmer air temperatures during the winter compared to locations further inland, due to the warming effect of the warm ocean currents.
Further, coastal regions under the influence of warm ocean currents may experience more dynamic weather patterns, including a greater potential for extreme weather events. Ocean currents, particularly warm currents, play a crucial role in shaping the climate and weather of coastal areas, influencing not only precipitation and temperature but also potentially storm activity. For example, higher ocean surface temperatures can contribute to more active hurricane seasons and powerful storms, which is critical for those living in coastal areas from the midlatitudes to the tropics.

During the great earthquake in chile in 1960, what migrated the loss of life
Final answer:
The loss of life during the great earthquake in Chile in 1960 was primarily caused by tsunamis and landslides.
Explanation:
The loss of life during the great earthquake in Chile in 1960 was primarily caused by tsunamis and landslides.
Tsunamis are large ocean waves that are generated by undersea earthquakes. The earthquake in Chile triggered a series of devastating tsunamis that struck coastal areas, resulting in significant loss of life.
Additionally, the earthquake caused extensive landslides in the region. Landslides occur when earthen material slides down a slope. They can bury and destroy anything in their path, leading to loss of life and property.

Find the volume of the composite solid. Round your answer to the nearest hundredth.
A. 239.23cm^3
B.246.08 cm ^3
C. 294.03 cm ^3
D. 308.78 cm^3
Answer:
C. [tex]294.03 cm ^3[/tex]
Explanation:
We must find two volumes, that of the quadrangular prism and that of the pyramid of the top and finally add them to get the total volume.
Quadrangular prism volume:
[tex]V_{1}=A_{b}*H[/tex]
where
[tex]A_{b}[/tex] is the base area
and H is the height
[tex]V_{1}=6.7cm*6.2cm*5.5=228.47cm^3[/tex]
Volume of the quadrangular pyramid:
[tex]V_{2}=\frac{A_{b}*H}{3}[/tex]
To find the value of height H we use pitagoras:
[tex]h=\sqrt{5.8^2-(6.7/2)^2} =4.7347cm[/tex]
Thus
[tex]V_{2}=\frac{(6.7cm*6.2cm)*4.7347cm}{3}=65.56cm^3[/tex]
The total volume is :
[tex]V=V_{1}+V_{2}=228.27cm^3+65.56cm^3=294.03cm^3[/tex]

what is the significance of hadrian's wall?
a.the wall has a monument to fallen roman soldiers
b.the wall marked the boundary between acient greece and rome
c.the wall was built as a temporary structure but lasted hundreds of years
d.the wall marked the northern defensive boundary of roman britain
The correct answer is - d. the wall marked the northern defensive boundary of Roman Britain.
The Hadrian wall was built under the rule of the Emperor Hadrian, after whom it got its name. The Roman emperor ordered the building of this wall because of the Pictish tribes from Scotland, which were constantly entering the northern parts of the territory of Roman Britain and were robbing the people. The purpose of the wall was to be a defensive line against the Picts, and in general, it did its job very nicely, keeping the Picts north of it.
Coastal urbanization does not increase the risk to human communities from which of the following natural disasters?
a.
earthquakes
b.
floods
c.
hurricanes
d.
cyclones
The correct answer is - a. earthquakes.
The earthquakes are unpredictable, and they can appear anywhere on the planet (most of them are on and around the plate boundaries though), so urbanizing the coastline doesn't increase or reduce the chances of this natural event.
The only consequence that can appear by an earthquake, on an urbanized coast, is if the earthquake appears in the water and causes a tsunami, but than again, it is something that is caused by the earthquake, not the direct impact of the earthquake itself.
Correct answer choice is :
An earthquake is the shaking of the surface of the Earth, emerging from the unexpected discharge of energy in the Earth's lithosphere that generates seismic waves. Earthquakes can differ in size from those that are so vulnerable that they cannot be responded to those severe enough to toss people around and wreck whole cities. The seismicity, or seismic activity, of an area, is the frequency, type and size of earthquakes encountered over a period of time.

What is time?Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future.
It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience.
Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars.
Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.
