Sedimentary rocks
Sedimentary rocks are created by accumulating existing rocks or fragments of extinct organisms on the Earth's surface.
Igneous rocks
Igneous rocks are defined as types of rocks that are formed when molten rock (rock liquefied by intense heat and pressure) cools to a solid state.
Metamorphic rocks
Metamorphic rocks are formed when rock changes over a period of time due to a lot of physical changes like pressure, heat and different chemical activity.
Geosyncline :
A geosyncline is a large-scale depression in the Earth’s crust containing very thick deposits. A narrow, shallow, elongated basin with a sinking bottom in which a considerable thickness of sediments was deposited by the river coming from Angaraland and Gondwana land is called a ‘Geosyncline’.
