Answer:
the answer isn't letter B. magnetic fields of Earth.
Explanation:
Radioactive isotopes decay and they released heat, more heat was generated and earth was hotter than it is today.
Plastic deformation occurs when pressure is applied to a substance and this results in a change of shape of the solid. This occurs to rocks when they undergo metamorphism by pressure. A metamorphic rock is formed by the transformation of preexisting solid rocks under the influence of temperature and pressure. Extreme pressure in metamorphism causes some rocks to be foliated or have a banded appearance. Granite undergoes metamorphism to form gniess.
