Question 3

The Grand Canyon's rock layers are primarily sedimentary rocks, which form in layers (strata) over time from sediment deposition. Igneous rocks form from magma/lava, granite is a type of igneous rock, and metamorphic rocks form from existing rocks under heat/pressure, not typically in layered stacks like sedimentary.

Sedimentary rocks form from the weathering, erosion, and deposition of pre - existing rocks, which can be igneous (formed from magma) or metamorphic (formed from other rocks under heat/pressure). Limestone and sandstone are types of sedimentary rocks, extrusive/intrusive are types of igneous rocks, and quartz/calcite are minerals, not rock types that form sedimentary rocks.

Answer:

C. sedimentary rock
