________________ is when the energy from the sun heats up different areas on Earth's surface at different rates and to different degrees.

The phenomenon you're referring to is called "Uneven Solar Heating." Here's a step-by-step explanation:

1. The Sun emits solar radiation, which travels through space and reaches the Earth.
2. This solar radiation is absorbed by the Earth's surface, heating it up. This is the primary source of heat for our planet.
3. However, this heating is not uniform or even across the entire surface of the Earth. This is due to several factors, including the angle at which the sunlight hits the Earth, the rotation of the Earth, and the different types of surfaces on the Earth (like water, land, and ice).
4. For example, the equator receives sunlight at a more direct angle than the poles. This means that the sunlight is more concentrated at the equator, causing it to heat up more than the poles.
5. Similarly, land surfaces heat up and cool down more quickly than water surfaces. So, areas with large bodies of water will experience slower heating and cooling compared to areas with lots of land.
6. This uneven heating of the Earth's surface by the sun leads to the creation of different climate zones and weather patterns, and drives the circulation of the atmosphere and oceans.
