Igneous rocks and sedimentary rocks.

Igneous rocks form from the cooling and solidification of molten rock (magma or lava).

Magma is hot, liquid rock found beneath the Earth's surface.

Lava is molten rock that has erupted onto the Earth's surface.

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Cementation is the process where sediments are glued together by minerals precipitating from water.

Erosion is the process by which rock and soil are worn away and transported by natural forces such as wind or water.

Weathering is the breaking down of rocks into smaller pieces by natural processes.

Igneous rocks form from molten rock, while sedimentary rocks form from the accumulation of sediments.

Energy from within the Earth can melt rock into magma, leading to the formation of igneous rocks.
