What are some similarities and differences in the way in which these rocks formed igneous vs. sedimentary

Igneous is formed by cooled magma (molten rock) and Sedimentary is formed  by wear and tear of the earth (erosion).

Igneous rocks and Sedimentary rocks both are both created under very hot temperature.

Igneous rocks are formed by the cooling of magma(molten rock) inside the Earth or on the surface while Sedimentary rocks are formed from the products of weathering by cementation or precipitation on the Earth's surface.
