What materials are sandstone made out of?

Answer 1

When the waves erode cliffs, large pieces of rock(BOULDERS) fall off and crash down to the beach below. Pieces break off the boulders until they eventually are worn down to pebbles.. The pebbles are then eventually worn down to sand due to the force of the waves. Sandstone(sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains.Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Like sand, sandstone may be any colour, but the most common colours are tan, brown, yellow, red, gray, pink, white and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colours of sandstone have been strongly identified with certain regions.

Rock formations that are primarily composed of sandstone usually allow percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Fine-grained aquifers, such as sandstones, are more apt to filter out pollutants from the surface than are rocks with cracks and crevices, such as limestone or other rocks fractured by seismic activity.

Sandstone is mined by quarrying. It is sometimes found where there used to be small sea areas. It is usually formed in deserts or dry placeslike the Sahara Desert in Africa, the Arabian desert in the Middle East and the Australian desert. In the western United States and in central Australia, most sandstone is red.[1]

Answer 2

Sandstone is made of sand which over the years has been cemented together.

Answer 3

Stone is made from high heat and high compression under the earth's surface.

Answer 4

Sandstone is made from the natural process of compressed sand. This happens in oceans, rivers and places with high amounts of pressure.

Answer 5

Sandstone is made out of two different materials, matrix and cement.

Answer 6

Sand is basically a certain size range of rock or mineral particle. Sandstone is usually made of quartz particles, although some sandstone is composed of a variety of particles.

Answer 7

Sandstone is made out of sand that was formed together.
