Question

(Q005) Identify the true statement. a. Magma is the term for very hot rock that is molten; when it cools and hardens, it's called lava. b. Igneous rocks form when pre-existing rocks undergo changes in response to heat and pressure. c. Hot, molten rock that cools and hardens produces metamorphic rocks. d. Sedimentary rocks form when pre-existing rock grains are cemented together.

Answer 1

Answer:

d. Sedimentary rocks form when pre-existing rock grains are cemented together.

Explanation:

• Sedimentary rocks are formed from the erosion and deposition of preexisting rocks that are accumulated on the surface of the earth. If these rocks like igneous are buried deep they get compacted and form sedimentary rocks.
