Question

Give two examples of rocks which are most widespread on the Earth.

Answer 1

1. Sandstone: It is a common sedimentary rock formed from compacted sand grains. It is widely spread because rivers, winds, and seas deposit sand over large areas, which later hardens into rock.

2. Limestone: This sedimentary rock forms from the remains of marine organisms like shells and corals. It covers large regions because it forms in shallow sea beds that were once widespread on Earth.
