Answer:
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.
Answer:
A) Energy from Earth’s hot interior produces magma which then cools
and crystallizes into igneous rock.
Explanation:
Energy from Earth’s hot interior causes extreme temperature and pressure which produces magma. This magma is present in liquid state that cools and crystallizes into igneous rock. Metamorphic rocks are formed from other rocks due to high heat or pressure. Earth movements can cause rocks to go deeply into the earth which causes the rocks are heated and put under great pressure. Sedimentary rocks are formed when sediment is deposited due to air, ice, wind, gravity, or water flows carrying the particles in suspension.
