Choose all the answers that apply. The thermosphere:

is divided into the ionosphere and exosphere
contains the ozone layer
is where auroras happen
increases in temperature as altitude increases
is used for orbiting satellites

temperature is not always increasing due to complex effects of nonlinear density functions and pressures so all apart from temperature are true

1- Option (A) and (D)

2- Option (B)

Explanation:

Thermosphere is the outer layer of the atmosphere comprising the space and some gas such as hydrogen and helium. Here the temperature rises with the increasing height, which is due to the direct sunlight from the sun. The auroras formed in this region due to the release of the charge particles while striking of the earth's magnetosphere.

The earth is comprised of both the continental as well as the oceanic plate and these plates are constantly in motion due to the force exerted by the convection current generating in the mantle. This phenomenon is known as the plate tectonic theory.

Thus, the correct answers are mentioned above.

the answer is b.) hydrogen bonds between bases.
