Write the differences between sedimentary and metamorphic rocks.
Answers
Answer:
Sedimentary rocks are formed by the erosion, transportation and deposition of sediments while metamorphic rocks are the result of the transformation of other rocks. Rocks that are subjected to intense heat and pressure change their original shape and form, and become Metamorphic rocks.

Sedimentary rocks are derived from sediments of pre-existing rocks, fossils, and tiny pieces of animal remains.
Metamorphic rocks are derived from other rocks.
Sedimentary rocks are formed when sediments are accumulated, deposited, and cemented at the bottom of water bodies.
Metamorphic rocks are formed when other pre-existing rocks go through chemical and physical changes due to heat and pressure
Sedimentary rocks have a fragmentary structure and contain an inner layering called bedding.
Metamorphic rocks are very hard and may appear to be banded or layered
The texture of sedimentary rocks depends on their clast, age, and depositional setting. These are generally grainy.
The texture of metamorphic rocks is foliated due to pressure. Some rocks may even appear to be non-foliated and banded
Sedimentary rocks are of three types – clastic sedimentary rocks (detrital), organic sedimentary rocks (biochemical), and chemically precipitated sedimentary rocks.
Metamorphic rocks can be divided into two basic categories – foliated metamorphic rocks and non-foliated metamorphic rocks.
Limestone, iron ore, chalk, coal, sandstone, siltstone, shale, flint, etc.
Slate, marble, quartzite, phyllite, gneiss, hornfels
