5.2 Weathering and Erosion. Bedrock refers to the solid rock that makes up the Earth's outer crust. Weathering is a process that turns bedrock into smaller particles, called sediment. Mechanical weathering includes pressure expansion, frost wedging, root wedging, and salt expansion.Chemical weathering includes carbonic acid and hydrolysis, dissolution, and oxidation.

Metamorphic rocks are rocks that have changed from one type of rock to another. While sedimentary rock is formed from sediments, and igneous rock is formed from molten magma, metamorphic rock is rock made from pre-existing rocks. These rocks undergo a change, either caused by high heat, high pressure, or exposure to mineral rich hot liquid, which …

Sedimentary Rock Formation. Accumulated sediments harden into rock by a process called lithification. Two important steps are needed for sediments to lithify. Sediments are squeezed together by the weight of overlying sediments on top of them. This is called compaction. Cemented, non-organic sediments become clastic rocks.
