Batholith
Batholith explained in an easy to understand way:
Imagine trying to make a jelly dessert, but you accidentally leave it too long in the mold, and it solidifies completely inside, making it difficult to remove. This is similar to how a batholith forms when magma cools and solidifies beneath the Earth's surface without erupting as lava. Just like the jelly hardens within the confines of the mold, the magma cools and crystallizes into a massive rock formation within the crust, creating a batholith.
Practice Version
Batholith: A large rock mass that forms when magma cools inside Earths crust. Batholith. A batholith is a huge formation of rock that solidifies deep beneath the Earth's surface.
