* Weathering is the process of breaking down rocks into smaller pieces. This can happen through:
* Physical weathering: Forces like freezing/thawing, abrasion by wind or water, and plant roots break down the rock.
* Chemical weathering: Reactions with water, acids, or oxygen alter the rock's composition, weakening it.
* Erosion is the process of moving weathered rock fragments from one place to another. This is primarily caused by:
* Wind: Blowing sand can wear down rocks and carry away smaller pieces.
* Water: Rivers, waves, and rain can transport weathered rock.
* Gravity: Rocks can fall or slide down slopes, moving them to new locations.
Think of it like this:
Imagine a large boulder on a mountainside.
* Weathering: Rainwater seeps into cracks in the boulder, freezes, and expands, breaking off pieces.
* Erosion: The broken pieces are then picked up by wind or rain and carried down the mountain.
Both weathering and erosion are constantly working together to shape the Earth's surface. They are often intertwined, with weathering providing the material for erosion to transport.
