Sedimentary rock, rock formed at or near the Earth's surface by the accumulation and lithification of sediment or by the precipitation from solution at normal surface temperatures. Sedimentary rocks are the most common rocks exposed on the Earth's surface but are only a minor constituent of the entire crust.

Earth Floor: Cycles -

The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals.

What are sedimentary rocks? -

Clastic Sedimentary Rocks: Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming .

Rock cycle - Simple English Wikipedia, the free encyclopedia

The rock cycle is the process by which rocks of one kind change into rocks of another kind.. There are three main kinds of rocks: igneous rock, metamorphic rock, and sedimentary rock.Each of these rocks can change into the other kinds by physical processes: cooling, melting, heat, weathering/erosion, compacting (squeezing tightly together), cementing, and pressure.

sedimentary cycle A cycle which comprises the weathering of an existing rock, followed by the erosion of minerals, their transport and deposition, then burial. First- cycle sediments are characterized by the presence of less resistant minerals and rock fragments.

Feb 01, 2013 · Sedimentary Rock. Small grains of exposed rock can be broken off by the action of wind and water or broken apart as water freezes in cracks. This can affect any type of rock, not just igneous. As time passes, these grains of rock accumulate in the slow currents in rivers or river mouths, low areas, or other quiets spots.

Rock Cycle Process | Sciencing

Any rock cycle explanation needs to begin with the three major types or families of rocks: igneous, sedimentary and metamorphic. Igneous rock forms when magma – molten rock – cools and solidifies. This rock-forming process may occur underground at depth, in which case the product is an intrusive (or plutonic) igneous rock, such as granite or gabbro.

Lithification—Sediments to Sedimentary rocks. Sedimentary rocks are rocks made of lithified sediment. Sediments are grains of rocks, minerals, or mineraloids deposited on the surface of the earth. Reflect on the rock cycle for an indication of the relationships between the rocks that erode to become sediments and sedimentary rocks.

The Three Categories of Rocks and the Rock Cycle - dummies

The Three Categories of Rocks and the Rock Cycle. Sedimentary: Sedimentary rocks are either detrital or chemical. Detrital rocks are formed by the compaction of separate particles, or sediments, into a rock. The particles are pieces of a different, pre-existing rock that have been weathered and transported by wind, water, ice, or gravity.

Sedimentary Rocks | Mineralogy4Kids

Any rock (igneous, sedimentary, or metamorphic) exposed at the Earth's surface can become a sedimentary rock. The forces of wind, rain, snow, and ice combine to break down or dissolve (weather), and carry away (transport) rocks exposed at the surface. These particles eventually come to rest (deposited) and become hard rock (lithified).

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...
