A student made the table below to compare high air pressure and low air pressure. Which correction is required to make the table correct?

a table comparing air pressure. High pressure has more air above pressing down and results in stormy weather. Low pressure has less air above pressing down and results in cloudy weather.

High pressure results in clear skies.
High pressure results in less air below pressing up.
Low pressure results in more air above pressing down.
Low pressure results in sunny weather.

Answer:

high pressure results in clear skies

Image shows a lake, a factory, a cloud in the sky, a cow, dead organisms, a tree, and the sun. An arrow from the sun to the tree is labeled A. An arrow from the sky to the tree is labeled B. The sky is labeled C above the cloud. The letter D is in the air and an arrow points from it down to dead organisms. An arrow points from dead organisms to the ground labeled E. An arrow points from the cow into to the sky labeled F. An arrow points from the factory to the sky labeled G. An arrow from the sky to the lake is labeled H above the lake.
Using the diagram above, match the description to the corresponding location in the carbon cycle model. Provide the letter only.

Images shows a lake labeled carbonates in water, a cow labeled animal respiration, a tree labeled photosynthesis, a factory labeled factory emissions, the sun labeled sunlight, a cloud labeled carbon dioxide in atmosphere, another tree labeled plant respiration, an arrow from organic carbon to dead organism, and fossils and fossil fuels. Arrows are labeled as follows: A from the sunlight to photosynthesis, B from carbon dioxide in atmosphere to photosynthesis, C from factory emissions to carbon dioxide in atmosphere, D from carbon dioxide in atmosphere to carbonates in water, E from dead organisms to fossils and fossil fuels, and F from plant respiration to the sky.


Using the diagram above, answer the following questions:

True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.

In Kevin’s favorite comic book, the superhero has special powers. In one adventure, the superhero must stop an evil villain who threatens to destroy the city with a powerful energy blast.

As he confronts the villain, he makes the following claims:
1: “I can create an energy force field to save the city.”
2: “I can destroy the energy before it destroys the city.”
3: “I can convert all the energy before it can do any harm to the city.”
4: “I can absorb all the energy and make it go away.”

If the superhero must obey the law of conservation of energy, which of the above can he actually do?

a. 1

b. 2

c. 3

d. 4

Why have ice ages come and gone?

A student drank a bottle of water during a car ride up a mountain. At the top of the mountain, the student capped the plastic bottle. During the drive back down the mountain, what might happen to the bottle?

A) It will expand because the air is lower at the bottom of the mountain.

B) It will contract because the air pressure is higher at the bottom of the mountain.

C) It will become lighter. The air particles in the bottle weigh less because they are from the top of the mountain.

D) It will not change because it is empty and contains no air.

Which statement accurately describes in terms of energy what happens when water turns to steam?
The water releases energy which causes chemical bonds to break, changing water to steam.
The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to gas.
The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas.
The water absorbs energy which causes chemical bonds to break, changing water to steam.
