contains the ozone layer
is divided into the ionosphere and exosphere
is where auroras happen
is used for orbiting satellites

which of the following statements is true?
the earth's core is made of liquid metal.
convection currents in the mantle cause the movement of crustal plates.

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.
