composition of rocks encyclopedia of earth

Rock Encyclopedia Britannica

Feb 12, 2021 Rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. Rocks are commonly divided into three major classes according to the processes that resulted in their formation.

More

Rock Encyclopedia

Rocks with this cooling history are referred to as coarse-textured igneous rocks. The mineral composition of igneous rocks falls roughly into four groups: silicic, intermediate, mafic, and ultramafic. These groups are distinguished by the amount of silica (SiO 4), iron (Fe), and magnesium (Mg) in the constituent minerals.

More

Rock (geology) Wikipedia

A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. Rocks are usually grouped into three main groups: igneous rocks, metamorphic rocks and sedimentary rocks. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere.

The Composition of Earth: Rocks and Minerals

Earth’s crust is compositionally the most varied part of the planet. It is dominated by silicate minerals, among which eight elements are pre-eminent (oxygen, silicon, aluminum, magnesium, iron, calcium, sodium, and potassium). With the advent of life, atmospheric carbon has also become locked into the crust as carbonate fossil remains.

Earth’s structure and composition Encyclopedia Britannica

Earth is composed predominantly of a large mass of igneous rock with a very thin veneer of weathered material—namely, sedimentary rock. Whereas sedimentary rocks are produced by processes operating mainly at Earth’s surface by the disintegration of mostly older igneous rocks, igneous—and metamorphic—rocks are formed

Earth's crust Wikipedia

Earth's crust is a thin shell on the outside of Earth, accounting for less than 1% of Earth's volume.It is the top component of the lithosphere, a division of Earth's layers that includes the crust and the upper part of the mantle. The lithosphere is broken into tectonic plates whose motion allows heat to escape from the interior of the Earth into space.

mantle National Geographic Society

Aug 11, 2015 The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth’s total volume.

The Interior of the Earth USGS

Between 100 and 200 kilometers below the Earth's surface, the temperature of the rock is near the melting point; molten rock erupted by some volcanoes originates in this region of the mantle. This zone of extremely yielding rock has a slightly lower velocity of earthquake waves and is presumed to be the layer on which the tectonic plates ride.

Moon rock Wikipedia

In some regards, lunar rocks are closely related to Earth's rocks in their isotopic composition of the element oxygen. The Apollo Moon rocks were collected using a variety of tools, including hammers, rakes, scoops, tongs, and core tubes. Most were photographed prior to collection to record the condition in which they were found.
