Name Exploration Student Worksheet: Earth's Interior

Question:

1. What is the composition of oceanic and continental crustal rocks in a model of Earth's interior?

Answer:

Oceanic and continental crustal rocks have different compositions and appear in specific layers of Earth's interior.

Explanation: The composition of oceanic crustal rocks primarily consists of basalt, which is rich in iron and magnesium. On the other hand, the composition of continental crustal rocks consists of a variety of igneous, sedimentary, and metamorphic rocks such as granite, limestone, and shale. In a model of Earth's interior, oceanic crustal rocks would appear in the uppermost layer known as the crust, specifically in the oceanic crust. Continental crustal rocks would appear in the continental crust layer.
