18. Steve is making a model for geology class, showing how rocks form. He is wondering if his model should show how an igneous rock formation underneath Earth’s outer layer could turn into a sedimentary rock formation. Is this possible?

Responses

a
Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.
Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.

b
Yes, energy from Earth’s interior can cause igneous rock to break into small rock pieces that form sedimentary rock.
Yes, energy from Earth’s interior can cause igneous rock to break into small rock pieces that form sedimentary rock.

c
No, sedimentary rock forms at Earth’s surface because energy from the sun causes rock to weather, but igneous rock under Earth’s outer layer is not exposed to energy from the sun.
No, sedimentary rock forms at Earth’s surface because energy from the sun causes rock to weather, but igneous rock under Earth’s outer layer is not exposed to energy from the sun.

d
No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock

The correct response is:

a Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.

This option accurately describes the process of how igneous rocks can be weathered to form sediments, which can then accumulate and lithify into sedimentary rocks. Sedimentary rocks can indeed form from the weathering and erosion of igneous rocks, among other sources.
