Consistently, you get the chance to see a ton of rocks around you – on the mountains, around the riverbeds, in the parks and even in the city. Have you at any point thought about what are these stones made of? Rocks come in a wide range of hues, shapes, and estimates and no two rocks are actually similar.

How are rocks characterized?

Geologists have ordered rocks into three essential gatherings based on their development in nature. Molten, Sedimentary and Metamorphic.

  • Molten rocks

Molten rocks are otherwise called ‘fire rocks’. Volcanic rocks start their life in liquid structure much beneath the outside of the earth. At whatever point there is a volcanic ejection, they are shot out of a fountain of liquid magma as magma, and are cooled once again into rocks as they hit the ground.

Kinds of Igneous rocks

There are two kinds of volcanic rocks found in nature,

  • Meddling molten rocks that set underneath the world’s surface.
  • Extrusive volcanic rocks that set on the outside of the earth.
  • Sedimentary rocks

Sedimentary rocks are framed when bits of shake and material, for example, shells and sand get pressed together. Together, every one of these particles are known as residue. Slowly, over some stretch of time, these residue solidify and transform into a stone.

Nature – Sedimentary rocks are commonly delicate and may break separated or disintegrate effectively. The majority of the stones that you see on the ground like sand, rocks, or stones are sedimentary rocks. A few instances of sedimentary rocks are limestone, sandstone and shale.

  • Changeable rocks

Changeable rocks are made out of the initial two kinds of rocks, profound inside the world’s outside. We call these transformative or ‘changed’ rocks. At times sedimentary and volcanic rocks are exposed to weights and warmth so extreme that they are totally changed. They become changeable rocks!

Nature – Metamorphic shakes regularly have lace like layers and may have glossy precious stones. Instances of this stone kind incorporate marble and gneiss.

What is the stone cycle?

The procedure of the development of every one of the three sorts of shake is known as the Rock cycle.
