How Rocks Form: Igneous Rocks, Sedimentary Rocks ...
igneous rocks: formed by the cooling and hardening of magma (molten rock) from inside Earth. 2. sedimentary rocks: formed by the compaction and cementing of layers of sediment (rock fragments, plant and animal remains, minerals from water) 3. metamorphic rocks: formed by the effect of heat and pressure on other rocks.

Sedimentary Rocks Geology
Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris. Photos and brief descriptions of some common sedimentary rock types are shown on this page. Coal is an organic sedimentary rock that forms mainly from plant debris. The plant debris usually accumulates in a swamp ...

Sedimentary Rock Formation
Cementation happens as dissolved minerals become deposited in the spaces between the sediments. These minerals act as glue or cement to bind the sediments together. The process of sedimentary rock formation takes millions of years to complete only to begin a new cycle of rock formation. The Rock Cycle. Sedimentary Rocks

Sedimentary Rock: Face of the Earth
Sedimentary rock is formed when mineral matter of plants and animals settle out of water and, less commonly, air or ice. The most common materials for sedimentary rocks are fossils, formed when sediment covered dead plants and animals as the sediment changed into rock. The remains are outlines of the dead plants and animals.

Sedimentary Rock Formation Models
ROCKS AND LAYERS Most of the rocks exposed at the surface of Earth are sedimentaryformed from particles of older rocks that have been broken apart by water or wind. These sedimentary particles may bury living and dead animals and plants on the lake or sea bottom. The sediments at the bottom of the pile become rock.

Learning about Sedimentary Rocks for Kids. Sedimentary rocks are made from sediments – bits of dirt, sand, rocks, shells, bones, etc. – that settle into layers. The older layers are on the bottom. They settled first. With a little bit of pressure and time, the sediments stick together and form the rocks we see.

Sedimentary rock. Sedimentary rocks are formed from overburden pressure as particles of sediment are deposited out of air, ice, or water flows carrying the particles in suspension. As sediment deposition builds up, the overburden (or 'lithostatic') pressure squeezes the sediment into layered solids in a process known as lithification...
