How does the Sun's energy drive convection in the Earth's atmosphere? The Response area's energy warms the land and Response area on Earth. As they heat up, the Response area above them becomes warmer and Response area dense and begins to Response area. Near the top of the atmosphere, the air cools down and becomes Response area dense and begins to Response area, creating a circular motion. How does the Sun's energy drive convection in the Earth's oceans? The Sun's energy warms the oceans on Earth. The warm water moves towards the Response area and the colder water moves towards the Response area , creating a circular motion.
