What is the name of Earth’s most abundant mineral?

Feldspar
Granite
Limestone
Quartz

The correct answer is: Feldspar

Feldspar is the most abundant mineral on Earth, making up about 60% of the Earth's crust. Granite and limestone are both types of rocks, not minerals. Quartz is relatively abundant on Earth, but not as abundant as feldspar. Additionally, while other minerals may be more abundant in certain locations (such as iron in the Earth's core), feldspar is the most abundant mineral overall. Therefore, A is the correct answer.
