The three types of rock are:

1. **Igneous Rock**: 
   - **Formation**: Igneous rocks are formed from the solidification and cooling of molten rock material called magma (when below the Earth's surface) or lava (when it erupts onto the surface). If the cooling occurs slowly beneath the surface, larger crystals form, resulting in intrusive igneous rocks (e.g., granite). If the cooling occurs quickly on the surface, smaller crystals form, resulting in extrusive igneous rocks (e.g., basalt).

2. **Sedimentary Rock**: 
   - **Formation**: Sedimentary rocks are formed through the accumulation and compaction of mineral and organic particles over time. This process often occurs in layers, where sediments are deposited in bodies of water, on land, or in other environments. Over time, these sediments are compacted and cemented together, forming rocks such as sandstone, limestone, and shale. Sedimentary rocks can also form from the remains of plants and animals, leading to fossil-rich deposits.

3. **Metamorphic Rock**: 
   - **Formation**: Metamorphic rocks are formed from the alteration of existing rocks (igneous, sedimentary, or other metamorphic rocks) due to changes in temperature, pressure, and/or the presence of chemically active fluids. This process, known as metamorphism, can cause physical and chemical changes in the rock, resulting in new mineral formations and textures. Examples of metamorphic rocks include schist, gneiss, and marble.
Igneous rocks form from cooling magma or lava, sedimentary rocks from compacted sediments, and metamorphic rocks from altered existing rocks.
