If you're hiking in the mountains and find a cliff of granite which of these statements must be true? a) the granite formed near the earths surface b) the granite was uplifted or uncovered by erosion c) the magma that formed it cooled relatively quickly d) the granite contained continued very little feldspar and quartz

Granite is the most abundant volcanic rock in found at the crust of the Earth. Granite forms for the slow crystallization of magma deep bellow the surface of the Earth, so we can rule out statements A and C. Granite is composed primarily of feldspar and quartz, so we can rule out statement D as well. Since granite forms deep beneath the crust of the Earth, it is exposed in the surface thanks to tectonic processes and erosion.

We can conclude that the correct answer is B) the granite was uplifted or uncovered by erosion
