Question

which of the following statements is true?
oa. fossils are frequently found in metamorphic rock.
ob. sedimentary rocks are formed as a direct result of chemical weathering.
oc. extrusive igneous rocks, found in the earths lithosphere, are not subject to weather
od. igneous rocks form from the cooling and crystallization of magma.

Explanation:

Fossils are usually found in sedimentary rocks, not metamorphic rocks. Sedimentary rocks form from the accumulation and compaction of sediments, not directly from chemical weathering. All rocks in the lithosphere, including extrusive igneous rocks, are subject to weathering. Igneous rocks indeed form from the cooling and crystallization of magma.

Answer:

D. Igneous rocks form from the cooling and crystallization of magma.
