★ Must-know
📌 Internal forces originate inside the Earth and include tectonic plate movements, earthquakes, and volcanic activity, whereas external forces act on the Earth’s surface.
📌 Weathering is the breaking down of rocks, whereas erosion is the removal and transportation of weathered material.
Further detail
Internal forces build landforms; external forces break down, move, and deposit material.
