Chalk is a soft, white form of limestone. Flint is a hard, sedimentary form of the mineral quartz. Learn about igneous rocks, metamorphic rocks, other rocks and minerals or fossils.
Keeping this in view, what is the heat and pressure in sedimentary rocks?
Metamorphic Rock- Metamorphic rocks form when sedimentary, igneous, or other metamorphic rocks are subjected to heat and pressure from burial or contact with intrusive or extrusive igneous rocks. ("Meta" means change, and "morph" means form.) Quartzite is metamorphosed sandstone.
What does sandstone turn into under heat and pressure?
Gneiss is a high grade metamorphic rock. This means that gneiss has been subjected to more heat and pressure than schist. Gneiss can be formed from a sedimentary rock such as sandstone or shale, or it can be formed from the metamorphism of the igneouse rock grantite.
How are sedimentary rocks formed short answer?
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.
