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.
Answer:
Marble is the correct answer.
Explanation:
Marble rocks forms when limestone undergoes metamorphism.
Marble rock is formed from the limestones,when the limestone is influenced by heat and tremendous pressure it transforms in marble through a method called metamorphism.
During the metamorphism, limestone gets recrystallizes and result in the formation of interlocking carbonate mineral crystals that form the marble.
