the three types of sedimentary rocks

List of rock types - Wikipedia

The following is a list of rock types recognized by petrologists.There is no agreed number of specific types of rocks. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe rock types.

Sedimentary Rocks | Pictures, Characteristics, Textures, Types

What Are Sedimentary Rocks? Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris.

Igneous Metamorphic Sedimentary Rock Gallery

The Rock Gallery contains pictures and descriptions of common igneous metamorphic sedimentary rock. The igneous rocks are listed at the top of the page followed by metamorphic and sedimentary rocks.

Types of Rocks - Igneous, sedimentary, metamorphic

Types of Rock Geologists classify rocks in three groups, according to the major Earth processes that formed them. These are igneous, sedimentary, and metamorphic rocks.

How Rocks Are Formed – An In-depth Analysis

THE EARTH'S CRUST The whole earth is made of rocks & minerals. Inside the earth, there is a liquid core of molten rock and on the outside, there is a hard crust.

Rocks - the home of Minerals

There are three main classes of Rocks. They are classified according to how they originated. Igneous rocks form from cooling bodies of magma. Over time, various weathering processes erode these rocks and the resulting particles or chemicals settle into beds and are compressed and cemented into sedimentary rocks.

BBC - GCSE Bitesize: Rock types

Rocks found on the Earth's surface actually come from inside the Earth - so they tell us a lot about the Earth's interior. They are classified (organised) into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks.

Beach Stones Types - Creative Activities for all

As with all other rocks, there are three beach stones types according to how they originated: Igneous, Metamorphic and Sedimentary beach rocks.

Rock Types - Zephyrus

There are three types of rock: 1. Igneous: these are rocks that solidified directly from molten silicates, which geologists call magma.Examples are: granite, basalt, pumice and flint (which is a form of quartz).

Facies - Wikipedia

Ideally, a sedimentary facies is a distinctive rock unit that forms under certain conditions of sedimentation, reflecting a particular process or environment.Sedimentary facies are either descriptive or interpretative.

10(f) Characteristics of Sedimentary Rocks - Geography

Sedimentary rocks can be categorized into three groups based on sediment type. Most sedimentary rocks are formed by the lithification of weathered rock debris that has been physically transported and deposited.

The Geologic Column - Naturalism and The Theory of Evolution

One of the very foundations of evolution and popular science today is the "geologic column." This column is made up of layers of sedimentary rock that supposedly formed over millions and even billions of years.

Igneous, Sedimentary, and Metamorphic Rocks - ClassZone

The three types of rocks—igneous, sedimentary, and metamorphic—are all subject to processes that change one rock type into another. The images below show several types of rocks undergoing these processes.
