How do Batholiths and stock compare?

Hint: The large body of igneous rock which is formed inside the Earth’s surface. It is formed by intrusion and when the magma is solidified. The composition is granite. The stock is considered as the igneous intrusion which has 100 square km surface exposure.

Complete answer:
Batholith is considered as the rock which is a large body of igneous rock which is formed under the surface of the Earth. It is formed by the intrusion as well as when the magma solidifies. The composition is coarse grained rocks which are granite. The shape of the batholith is irregular which is inclined to twist the host rock. It has 100 square km surface exposure.

The stock is considered as the igneous intrusion which has 100 square km surface exposure. It differs from the Batholith since it is smaller than Batholith. The relationship of stock has an incongruous relationship with rocks. Many sticks are considered to be cupola of hidden Batholiths.
The most important distinction between stock and batholith is the area exposed at the surface. The surface area of the Batholith is at least 100 square km. There is less than 100 square km of stock. Batholiths are considered to be larger than stocks.

Note:A batholith is considered as the largest body which has irregular shape that cuts the rocks that are in surroundings. The granite is the composition of Batholith. A stock is considered to be like Batholith but it is smaller as compared to Batholith. The stock has 100 square km less than Batholith.
