Sedimentary rocks are made up of fragments of other rocks or organic matter that have been created in the past.
Clastic, organic (biological), and chemical sedimentary rocks are the three kinds of sedimentary rocks. Sandstone,
for example, is a sedimentary rock made up of clasts, which are bits of other rocks. Hard biological components
like as plants, shells, and bones are compacted into a rock to produce organic sedimentary rocks, which are
similar to coal. The weathering, or breaking down, of the exposed rock into minute fragments is the first step in
the production of clastic and organic rocks. These particles are transferred to a new area by wind, water, ice, or
biological activity as part of the erosion process. The lowest strata become compressed so tightly that they
develop once the silt settles someplace and enough of it gathers to form a solid rock. When molten hot material
cools and hardens, igneous rocks form. Igneous rocks can also be created in a variety of ways. Intrusive, or
plutonic, igneous rocks are those that originate deep within the earth. Extrusive, or volcanic, igneous rocks are
those that originate outside or on top of the Earth's crust. They have a coarse texture with large mineral grains,
indicating that they cooled down inside the earth for thousands or millions of years, allowing large mineral
crystals to grow. Rocks like basalt and obsidian, on the other hand, have incredibly minute grains and a fine
texture. This happens because when magma erupts into lava, it cools more quickly than it would if it stayed
inside the earth, giving crystals less time to form. When obsidian is ejected, it cools so quickly that the grains are
hard to perceive with the human eye.
