O

C

Explanation:

Using only renewable energy is a way that you can benefit the Earth. For example, if we switch to solar energy, then we would be more sustained because you can use solar energy more than once. Renewable resources are produced in a short time or a lot is available. So, the answer is C.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
