39. The granite domes in Yosemite National Park in California are part of a a. batholith

b. laccolith

A. Batholith is the right option.

Explanation:

It is large emplacement of igneus intrusive rock (plutonic rock). It forms from cooling magma deep in Earth's crust. They may have a uniform appeareance, but their structure is really complex.

a. batholith

Explanation:

Granite is an example of igneous rocks. Igneous rocks are rocks formed through the cooling of molten magma or lava. Lava's are molten magma that creeps or erupt to the surface of the earth crust before cooling.

Igneous rocks can be extrusive or intrusive igneous rocks. Extrusive igneous rocks are formed when lava cools rapidly at the surface of the earth to form the rocks while the intrusive igneous rocks are formed when molten magma cools at the interior of the earth crust.

Granite is an example of intrusive igneous or plutonic rocks that are formed from the crystallization of molten magma slowly cooling below the earth surface. The formation of this rocks are slow due to the high temperature available below the earth surface. Granite rocks are plutons.

Plutons are large bodies of intrusive igneous rocks that are usually coarse grain formed at the interior of the earth. A large congregation of plutons are known as batholith.

Generally, Batholith is a very large mass of intrusive igneous rocks forms below the earth crust. The granite dome in Yosemite National park in California has a very large amalgamation of this plutons known as batholith.
