In what type of rocks are most fossils found? metamorphic rocks sedimentary rocks granite and marble igneous rocks

Option (2)

Explanation:

Fossils are the dead remains of ancient plants and animals that are buried millions of years ago. These fossils are found to be embedded in the sedimentary rocks.

Sedimentary rocks are the rocks that are firmed due to the compaction and lithification of sediments. These sediments provide favorable conditions for the dead organisms to turn into a fossil.

The igneous rocks are formed from the crystallization of the magma at a certain depth and the metamorphic rocks are formed due to the increasing pressure and temperature conditions in the rocks. The rocks are not suitable for fossil preservation because the fossils are destroyed and are burnt during the formation of these metamorphic and sedimentary rocks.

Some examples of sedimentary rocks that contain fossils are sandstone, shale, and limestone.

Thus, the correct answer is option (2).

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
