Types of Weathering are… Mechanical – When rocks and other minerals are broken into smaller pieces. Chemical – When minerals are changed completely when they mix with water and air. Like metal changing to rust.
Loess is wind-blown silt, sand, and clay. Can form sand dunes 100’s of feet deep!
Examples? Precipitation – Mudslides – Avalanche –
Glaciation – changes in a landform made from a slowly moving sheet of ice (glacier) Moraines – rocks left behind after a glacier moves Creates new valleys, hills, or ridges
Through the process of weathering and erosion of rocks Humus – quality of soil 1. Texture of the soil 2. Amount of organic material in the soil
