Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.
Other sedimentary rocks called evaporites form when minerals come out of solution as water evaporates off.
Organic sedimentary rocks forms where the remains of plants and animals are deposited in layers.
Because water has a very high specific heat, it is very common that areas near oceans or large lakes tend to have more moderate and warmer climates than those that are away from these big bodies of water.
