Rock Transformation Review

Reina is making museum exhibits about two different rock types. How could energy have played a role in the different rock types forming?

• Energy causes different types of rock to change in different ways. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.

• Energy caused one rock type to form, but not the other. Rock that forms because of energy is a different type of rock than rock that forms without energy.

• Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces.

• Energy changes rock on different continents in different ways. Each continent on Earth has different rock that might form liquid or small rock pieces when exposed to energy.

Giovanni and his family go on a trip and they drive over a mountain range. Giovanni wonders how the rock they see as they drive over the mountain range might be different when they drive back home next week. What would you tell Giovanni about how the rock will change?

• The rock will probably change a lot. Rock is always changing and transforming.

• The rock is not likely to change very much. Most rock transformation processes happen very slowly.

• The rock will not change at all. Rocks just stay as they are.

• The rock might change if it is the right season.

Michelangelo's David is a statue that was carved in the early 1500's. The statue is make from marble, which is a type of metamorphic rock. How did the metamorphic rock used in David form?

• Melted and cooled

• broke into sediment and was compacted

• heated and put under pressure

• rock doesn't form; it stays as it is

Mining companies have technology that can detect rock formations underneath Earth’s outer layer. One mining company detects an igneous rock formation underneath Earth’s outer layer. The geologists working for the company wonder if material in this igneous rock used to be sedimentary rock at Earth’s surface. Can material in sedimentary rock become igneous rock? Explain your answer.

• Subducts, Melts & Cools

• Subducts, heat and pressure

• Uplift, weather and Erodes then compacts and cements
