- Hi! I'm Chloe, For today we're gonna tackle about Exogenic Processes. But first, Let's Dive in about What is Exogenic Processes?
- Exogenic processes are external processes that occur on or near the Earth’s surface and are driven by external forces such as the atmosphere, hydrosphere, and biosphere. These processes involve the breakdown and movement of materials on the Earth's surface and are primarily powered by energy from the sun.
