The third most abundant gas in the Earth's atmosphere is argon, which makes up about 0.9% of the atmosphere by volume. It follows nitrogen and oxygen in abundance.
Argon, despite its relatively low profile in discussions about Earth's atmosphere, holds a significant presence as the most abundant noble gas. Comprising approximately 0.93% of the atmosphere, its inert nature lends stability to atmospheric composition. Unlike reactive gases such as oxygen and nitrogen, argon remains unreactive, contributing to atmospheric equilibrium. Its prevalence, though often overlooked, underscores its crucial role in maintaining atmospheric stability and composition.

What is the independent variable in the graph?
Help me plz (this is middle school science)
Explanation:
Location A receives 200cm of rain each year, while Location B receives only 30cm because in location A cloud rises, and it expands and cools down because the surrounding atmospheric pressure decreases, then the cloud gets too large and falls down as rain. Whether in location B, this land is covered by rain shadow and receives less rain.
Once the rain passes from mountain range and it moves down to the other side, warms and dries out. This produces a rain shadow. The land which is covered by rain shadow is very dry and receives less rain. Precipitation and cloud cover the land on windward side of the mountain range.

What is tornadoes?
A tornado is fine, violently rotating column of air that expands from the base of the ground to the high level in air.
Tornado forms by the large thunderstorms. When the thunderstorms arises, the hot, cold and humidified airs blow with air. This cause spinning air current inside the clouds.
How to predict the tornadoes?The tornadoes occurs where the conditions in the favor of thunderstorm. As the large thunderstorms cause the tornadoes Thus the tornadoes can be predicted in the region where favorable conditions seem for the development of thunderstorms.
The likely conditions for a thunderstorms, when the middle air is cold and dry and the ground level air is humidified.
Wind profile keeps a important role for the storms. The low level wind flow in middle level and the strong wind flow at the high level cause the thunderstorms and so the tornadoes.
Scientists use wind flow and its profile and the temperature of air for the region to predict and detect the tornadoes. Hence, the option 4 is the correct option.

which two tools below would be the most useful in testing how the mass of an object can affect the distance it moves after being pushed
The two tools that would be most useful in testing how the mass of an object can affect the distance it moves after being pushed are balance and meter stick. The correct option is b.
What are tools?Any object used to accomplish a task can be referred to as a tool. Equipment typically refers to a collection of tools used to accomplish a particular task. A tool can also be non-mechanical.
The hammer, the wrench (also known as a spanner), the saw, the shovel, the phone, and the computer are some examples of tools that are often used nowadays. Tools can also be quite basic items like knives, pens, and pencils. One of the very first tools created by humans was the bludgeon, which is a stick or rock used as a weapon to destroy things.

The name of the large pore through which filtered water leaves the body of the sponge is osculum. The correct option is C.
What is a sponge?Sponges, members of the phylum Porifera, are a basal animal clade and the diploblasts' sister.
They are multicellular organisms with pores and channels that allow water to circulate through their bodies, which are made up of jelly-like mesophyll sandwiched between two thin layers of cells.
To obtain energy, animals require nutrients from other animals and plants. Because sea sponges lack chloroplasts and do not generate energy from sunlight, they are classified as animals.
Water is pumped directly into the sponge through pores called ostia and then out through an opening called the osculum.
The spongocoel is lined with choanocytes, which are specialized digestive cells that filter and absorb food.
Thus, the correct option is C.

A glacier is eroding the land over which it passes. It moves at a rate of 2 m per day. Currently, the glacier is 80 km from a small village. At current rates of movement, how many years before the glacier reaches the village? Plz help its due tomorrow and ill mark u brainliest!
Final answer:
It would take approximately 109.59 years for the glacier moving at a rate of 2 meters per day to reach the village that is 80 kilometers away.
Explanation:
The student asked how many years it would take for a glacier moving at a rate of 2 meters per day to cover the distance to a village that is currently 80 kilometers away. To solve this problem, we need to first convert the distance from kilometers to meters. Since 1 kilometer equals 1,000 meters, the distance in meters is 80 km × 1,000 = 80,000 meters.
Next, we calculate the number of days it would take to travel this distance by dividing the total distance by the daily movement rate of the glacier. The calculation would be 80,000 meters ÷ 2 meters/day = 40,000 days.
Finally, to find the number of years, we divide the number of days by the number of days in a year. This is 40,000 days ÷ (1 year/365 days) = 109.59 years. So, it would take approximately 109.59 years for the glacier to reach the village at the current rate of movement.
Which equation is used to determine the density of a substance? D = M/V D = M X V D = V/M D = MV2
Every substance, body or material has mass and volume, however the mass of different substances, bodies or materials occupy different volumes.
This is where density appears as a physical characteristic property of matter that establishes a relationship between the mass of a body or substance and the volume it occupies.
In formal words:
Density [tex]D[/tex] is defined as the relationship between the mass [tex]M[/tex] and volume [tex]V[/tex] of a specific substance or material and is expressed in the following equation:
The density is a scalar quantity and according to the International System of Units its unit is [tex]D=\frac{kg}{m^{3}}[/tex]
It should be noted that the density of a body is related to its buoyancy, a substance or body will float on another fluid if its density is lower.

Find the work done by a 25N force applied for 6 meters
Answer: W = 150J
Explanation: The work is defined as a measure of energy transfer when an object is moved by an external force.
So if we are applying a force of 25N for 6 meters, the work is done can be calculated as:
W = F*D where F is a force, and D is distance.
W = 25N*6m = 150 N*m
And Newton*meter = joule, so we have that:
W = 150J

What is the approximate weight of a 20-kg cannonball on Earth? 2 N 20 N 196 N 1,960 N
Answer:
Weight of the cannonball, W = 196 N
Explanation:
Mass of the cannonball, m = 20 kg
We need to find its weight on earth. The weight of an object on the earth can be calculated by the product of mass and acceleration due to gravity as :
[tex]W=m\times g[/tex]
[tex]W=20\times 9.8[/tex]
W = 196 N
So, the weight of the cannonball on the Earth's surface is 196 N. Hence, this is the required solution.
