For thousands, even millions of years, little pieces of our earth have been eroded--broken down and worn away
by wind and water. These little bits of our earth are washed downstream where they settle to the bottom of the rivers, lakes, and oceans. Layer after layer of eroded earth is deposited on top of each. These layers are pressed down more and more through time, until the bottom layers slowly turn into rock
sediments
Sandstone is a type of rock formed from tiny pieces of material such as sand. These grains are compacted and cemented together over time to create a solid rock structure. Sandstone is commonly found in sedimentary environments.
This is how they are formed: A river carries, (transports) pieces of broken rock to a lake or sea. The pieces of rock settle at the bottom, (they are deposited) They then form into layers. The sediments on top squish down the ones on the bottom, squeezing out all the water between the cracks. Over time, the sediments slowly cement together. It usually takes millions of years, but the layers eventually turn into sedimentary rocks.
== == A sedimentary rock is formed from sediments deposited by water on the bottom of rivers, lakes, and oceans. The sediments are pieces of earth that have eroded, or worn away and washed downstream into rivers, lakes, and oceans and then settled out. Therefore, a non-sedimentary rock is a rock that isn't sedimentary.
Weathering and erosion break igneous and other types of rock into smaller pieces called sediments.

ffffffffffffffff
Sedimentary rock.
Sandstone is a type of rock formed from tiny pieces of material such as sand. These grains are compacted and cemented together over time to create a solid rock structure. Sandstone is commonly found in sedimentary environments.
Sedimentary rock is so named because it is formed from sediments. The sediments could be particles of rock, sand, minerals, or organic material.

If the process of cementation is volcanic you get a "tuff". If the cementation post sedimentation of rock clasts you get a sedimentary rock which may be a breccia or a conglomerate.

Sedimentary rock can be formed from lithified sediments.
conglomerate rock has little pieces or pebbles formed or squished together.-niania87
