The astenosphere plays a key role in the plate tectonics theory because it is the one that provides the high temperatures, high pressure, and magma, that are the ones responsible for cracking up the crust on the surface.
The astenosphere, with the ability to crack the crust on the surface of the planet is creating the continental and oceanic tectonic plates, and it also provides the push force from bellow so that they can move across the globe and thus be creating the landscape on the planet.

Answer:
The true statement is option D. The two major factors determining the Earth's temperature are the Earth-Sun distance and the concentration of oxygen in the atmosphere.
Explanation:
The distance between the sun and the Earth is one of the factors that determines the temperature of the planet. The energy from the sun travels to the Earth, increasing the temperature.
The other fact that has a role in the Earth's temperature is the concentration of oxygen in the atmosphere. It can increase or decrease the temperature according to the amount of this. Oxigen contributes to the greenhouse effect, which helps to keep the temperature in a range that allows life to happen.
