acid rain while on a field trip to a park, you notice a statue that is very worn. you cannot figure out what the statue was supposed to be. you ask the park ranger about the statue. the park ranger tells you that this statue has not always looked this way. the park ranger shows you a picture of the statue that looks very different than the statue now and tells you the difference is caused by acid rain. 75 years ago today you wonder how acid rain is made. after researching, you learn that sulfur dioxides and nitrogen oxides dissolve very easily in water, causing the formation of acid rain. power plants release sulfur dioxides and nitrogen oxides into the air when they burn fossil fuels. looking at how the statue was changed by natural processes, you start wondering if rocks are changed in a similar way. you find a diagram that shows the rock cycle, which describes how different kinds of rocks are changed from one kind to another. rock cycle cooling & crystallization magma melting igneous rocks metamorphic rocks heat & pressure weathering & erosion sediments sedimentary rocks lithification (compaction & cementation) select to enlarge you notice that all three kinds of rocks can change to magma by the process of melting. which option best explains the source of the energy for this process? a energy from the sun b earths gravitational force c internal heat from earths core d convection currents in the mantle

Answer

Brief Explanations:

The energy for melting rocks to form magma comes from the internal heat of the Earth's core. The sun's energy is mainly involved in surface - level processes like weathering and evaporation, not in melting rocks to magma. Earth's gravitational force is not the main source of energy for melting rocks. Convection currents in the mantle are a result of the heat from the core, but the direct source of energy for melting is the internal heat from the core.

Answer:

C. internal heat from Earth's core
