Which of the following rocks would most likely contain a fossil? sandstone granite marble basalt

Option A. "Sandstone"

Explanation:

Fossils are the remains of dead animals and plants formed under rocks from millions of years.

There are basically three types of rocks metamorphic, igneous and sedimentary.

Sandstone are the type of sedimentary rocks, in which most of the fossils are found. they are made up of rock grain formed in low  temperatures and pressures which do not harm remaining fossil. fossils of mastodons and dinosaurs are the example found in sandstone.

Whereas granite  and basalt (igneous rocks) and marble (metamorphic rocks)  are formed under very high heat and pressure that can destroy fossil remains.

Hence, the correct option is A.

climate change and pollution
