Question

1. a geology student describes a rock sample she is studying in class. the rock sample is igneous rock, but the student wonders if the material that it formed from was part of a sedimentary rock formation millions of years ago. could this be correct? could the material for igneous rock come from sedimentary rock? a yes, if sedimentary rock is exposed to energy from the sun at earth’s surface for a long enough time, it can melt into liquid rock and form igneous rock. b yes, if sedimentary rock is moved below earth’s outer layer and exposed to energy from earth’s interior, it can melt into liquid rock and form igneous rock. c no, igneous rock can only form from other igneous rocks. sedimentary rock cannot change into igneous rock. d no, igneous rock forms under earth’s outer layer due to energy from earth’s interior, but sedimentary rock only forms at earth’s surface

Explanation:

Sedimentary rock can be transformed into igneous rock. When sedimentary rock is moved below Earth's outer - layer (crust) and exposed to high - temperature and pressure energy from Earth's interior, it can melt into magma (liquid rock). When this magma cools and solidifies, it forms igneous rock. The energy from the sun is not sufficient to melt sedimentary rock into liquid rock for igneous rock formation. Igneous rock can form from other rock types through the rock - cycle process, not just from other igneous rocks. Sedimentary rock can also be involved in the formation of igneous rock under the right conditions.

Answer:

B. Yes, if sedimentary rock is moved below Earth’s outer layer and exposed to energy from Earth’s interior, it can melt into liquid rock and form igneous rock.
