Sedimentary Rocks Sedimentary Rocks Sedimentary rocks are formed from layers of deposits laid down in lakes or seas. Over millions of years the layers of sediment build up resulting in the weight pressing downwards, creating high pressure, which squeezes the water out.
Sedimentary rocks are of three types: clastic, chemical and organic. Igneous rocks are made of magma, either on the surface of the earth or inside the crust. Igneous rocks are of two types: intrusive and extrusive. Both sedimentary and igneous rocks are the primary types of rock formation. Metamorphic rock is not a primary rock.

What two processes do sedimentary rocks undergo to become hard rock? compaction and cementation. facts about shale. clastic, made of silt. facts about sandstone. clastic, made of sand. facts about conglomerate. clastic, made of rounded rock fragments. facts about breccia.
Shale, sandstone, limestone, conglomerate, coal are some of the examples for sedimentary rocks. These rocks are usually rich in fossils. Fossils are the remains of the animals and plants, being preserved in rocks. Sedimentary rocks are found in a variety of colours.
Jun 04, 2017· Rocks are cool. Seriously! I talk today about sedimentary rocks: how they come to be, why they are awesome, and the sorts of things we can learn from them. I show a bit of my rock .
Nonfoliated metamorphic rocks are formed around igneous intrusions where the temperatures are high but the pressures are relatively low and equal in all directions (confining pressure). The original minerals within the rock recrystallize into larger sizes and the atoms become more tightly packed together, increasing the density of the rock.

How Do Organic Sedimentary Rocks Form? By Contributor; Updated April 24, 2017 . M. Kaye Hash . The Basics of the Rock Cycle. There are three different types of rocks that make up the Earth: metamorphic, igneous and sedimentary. As the Earth renews its crust, the sedimentary rocks become metamorphic and the metamorphic rocks become igneous.
