What is the main benefit of the energy absorbed by the atmosphere from the Sun's rays?

What rests on top of the tectonic plates?

• Atmosphere and biosphere

• Earth's inner and outer core

• Continents and oceans

• Clouds and rain

According to the theory of plate tectonics, what happens when plates move?

• The atmosphere gets warmer

• The oceans become saltier

• Changes in Earth's surface occur, such as the formation of mountains, volcanoes, and earthquakes
