Question

Define Sedimentary Rocks.​

Answer 1

${\bold{\green{\huge{Your\:Answer}}}}$

♣ 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.

♦Chemical sedimentary rocks,

such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.

♦Organic sedimentary rocks,

 such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.

♣ Formation

✍️ Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension.

✍️ This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.

✍️Sedimentary rocks are made when sand, mud and pebbles get laid down in layers.

✍️ Over time, these layers are squashed under more and more layers.

✍️Eventually, the layers are lithified – turned to rock. Sedimentary rocks can be formed in deserts , lakes, rivers and seas .
