Answer:
Rocks found on different mountains are different ages.
Explanation:
Radiometric dating of rocks and fossil records gives scientists an idea of the timelines of certain organisms. Fossils of long dead species found in different strata of rocks can be used to speculate the age and changes these organisms have experienced overtime.
Fossils found in the uppermost strata are indicative of organisms that died not quite long whereas fossils found in lower layers are indicate of organisms that died a long while ago. These studies also provide insight into the changes that the earth has experienced overtime.
Answer: (C) A hot spot
Explanation:
A hot spot is created in the volcanic peaks and it is basically developed over the plume. The mantle plumes are the areas of the up-welling and the hot mantle areas. Magma created by the problem area ascends through the unbending plates in the lithosphere layer.
It produces the dynamic volcano at the surface of the earth. In the mantle area, the hot spot are generated in which the rocks are get melted for generating the magma. The hot spot generated the heat are basically comes from the middle of the earth.
It is a completely false statement that the top of a sedimentary layer was deposited before the bottom.
