Half of the sun's energy reaches Earth's surface, is absorbed by land and oceans, and then transformed into what type of energy?
Air rises if it is warmer than the surrounding air. This transfer of heat energy through the atmosphere occurs because of _______
The direct transfer of heat from one substance to another substance that it is touching is called _______
Differences in Earth's temperature are due to the sun's uneven heating of the Earth's surface This causes areas of high and low pressure. The movement of air from an area of high pressure to an area of low pressure is called ______
