B. The air pressure increases.
C. The air has more moisture.
D.The air is thinner.
Thanks to anyone who helped!
Thx @butttttttt the answers are:
1.The air is thinner.
2.Meteors burn up in this layer to create shooting stars.
3.a diagram illustrating how plants use carbon dioxide, water, and sunlight to produce food and oxygen gas.
4.How are fossil fuels formed from the decay of dead plants and animals in the biosphere?
thanks again!!!! :)

Use the scenario to answer the question.
A student is examining scientific evidence to support the following claim.
“Life is possible because of the unique mixture of gases that cycle through the Earth’s spheres.”
Which evidence best supports the student’s claim?
a timeline detailing when an erupting volcano releases lava, ash, and gases
a photograph capturing a nighttime meteor shower
a diagram illustrating how plants use carbon dioxide, water, and sunlight to produce food and oxygen gas *********
an illustration demonstrating how the depletion of the ozone layer is not blocking out the sun’s ultraviolet rays
Which question can best be answered by studying a diagram of the carbon cycle?
How are fossil fuels formed from the decay of dead plants and animals in the biosphere? *********
How is surface water, underground water, and moisture in the atmosphere recycled?
How are fossil fuels processed and used to power industries?
How does the process of transpiration cause plants to release water through their leaves?
These are correct ur welcome :)
