Sun's Energy

What is the source of the thermal energy that heats our planet’s atmosphere?

• Earth's core

• Green plants

• The Sun

• Fossil Fuels

The Sun warms the atmosphere and drives convection currents because -

• warm air is less dense, so it rises.

• the warmed air cools and makes rain.

• the cooler land pushes away warm air.

• warm air, in contact with cool air, rotates.

Which of the following changes would remove the source of energy that generates the convection which makes wind here on Earth?

• Growing more vegetation in barren areas.

• Removing all the salt from sea water.

• Blocking all solar radiation.

• Reversing the rotation of Earth.
