Why are most fossils found in sedimentary rock, rather than in igneous or metamorphic rocks? What will be an ideal response?
To answer this question, we must examine how rocks form. Igneous rocks form at high
temperatures when magma cools and crystallizes. These temperatures are not conducive to
the preservation of organisms or traces of organisms.
Metamorphic rocks form from the exposure of existing rock to heat and pressure. In the
metamorphic process, fossil remains are likely to be destroyed or greatly altered.
