Weathering and Soil Formation — Chapter Summary

Rocks are aggregates of minerals

Rocks are aggregates of minerals and have no definite chemical composition. They form the solid part of the lithosphere and are important for building

Igneous rocks form when molten magma

Igneous rocks form when molten magma cools and solidifies. They may be intrusive, like granite, or extrusive, like basalt. They are hard, compact, and

Sedimentary rocks form from sediments deposited

Sedimentary rocks form from sediments deposited in layers over long periods in seas, lakes, rivers, and glaciers. They are also called stratified rock

Metamorphic rocks form when igneous

Metamorphic rocks form when igneous or sedimentary rocks change completely due to great heat and pressure, tectonic movements, or volcanic activity. E

Weathering is the static process

Weathering is the static process in which rocks and minerals break down or dissolve where they exist. It happens through physical, chemical, and biolo
