A | B |
weathering | processes that breaks rocks into smaller and smaller pieces |
sand, silt, & clay | three different sizes of sediment |
mechanical & chemical | two types of weathering |
mechanical weathering | physical process that changes the size and shape of rocks, not the chemical makeup |
chemical weathering | when chemicals change the minerals in rocks into different minerals |
carbonic acid | acid formed when water reacts with carbon dioxide gas |
ice wedging | water freezes in small cracks in rocks and makes them larger and larger until the rock is broken apart |
mountains | ice wedging happens more often here because of the climate |
plants and animals | cause mechanical weathering |
oxidation | chemical weathering caused by oxygen and water |
climate | the average weather in an area over many years |
cold climates | cause mechanical weathering to happen faster |
hot climates | cause chemical weathering to happen faster |
