Question

a scientist collects a core sample from 60 km deep in earth. which characteristic will she most likely observe in this sample? the sample has high iron content. the sample is very hot and liquefied. the sample mainly consists of granite. the sample is very young.

Explanation:

• The Earth's crust is divided into continental and oceanic crust. Continental crust is mainly composed of granite.
• A depth of 60 km is within the continental crust.
• Iron - rich materials are more common in the core.
• Liquefied materials (magma) are more likely to be found in the mantle (below the crust, starting from about 35 - 70 km in continental regions, but the upper part of the mantle is semi - solid in some models and the crust itself is solid).
• The age of rocks in the crust can vary, but granite is a characteristic rock of the continental crust.

Answer:

The sample mainly consists of granite.
