Here's a breakdown:

* Weathering: This is the process where rocks are broken down into smaller pieces by forces like wind, rain, ice, and chemical reactions.

* Erosion: This is the process where the weathered rock fragments are transported away from their original location by wind, water, or ice.

These broken down rock fragments are called sediment. They come in various sizes, from large boulders to tiny grains of sand and silt.

Examples of sediment include:

* Sand: Created from weathering and erosion of sandstone, granite, or other rocks.

* Clay: Formed from the breakdown of feldspar and other minerals.

* Gravel: Composed of larger rock fragments, usually from erosion of mountains or cliffs.

In summary: Weathering and erosion break down rocks into smaller pieces called sediment, which can then be transported and deposited elsewhere.
