Q:

Where in the world is granite found?

A:

Quick Answer

Granite makes up a portion of the Earth's crust, and exists in virtually all land areas around the world. Granite forms the middle layer of the Earth's core, along with several other minerals and rocks. It forms the basis of the continental crust, and it also exists in seabeds.

Full Answer

Granite belongs to the class of igneous rocks. It forms from two primary minerals, quartz and feldspar. It occurs in batholiths, or granite deposits, and appears naturally in mountain ranges and hills. Most granite comes in various shades of gray, although some rocks come in white and pink shades. Tiny specks of minerals along the outsides and in the core give granite a distinct appearance. Depending on location, granite sometimes has traces of other minerals, such as mica and hornblende.

Granite forms from the melting process of breaking down shale and sandstone. The resulting granite produced by this activity collects in deep deposits around the world. In North America, granite appears naturally in the Canadian Shield, forming a layer of bedrock. As a plentiful and cost-effective rock, it appears in many residences and commercial establishments. Granite makes a popular choice for home decorating, and serves as a decorative stone for commercial building improvements.

    How does the Earth's crust recycle itself?

    A:

    The Earth's crust recycles itself through subduction of crustal material into the mantle and upwelling of magma from the mantle. These processes are described by plate tectonics, a commonly accepted theory that explains the large-scale movements of the Earth's lithosphere.
