Rock Cycle

What geologic process changes pieces of rocks, minerals and other materials into sedimentary rocks?

• Compacting and Cementing
• Cooling
• Heat and Pressure
• Melting

.     Declan observed a rock that he found at the beach. He concluded that the rock was sedimentary. Which observation best supports this conclusion?

• A. the yellow color

• B. the hardness of the rock

• C. the layers within the rock

• Glassy Surface

What geologic process can change granite (igneous rock) into gneiss (metamorphic rock)?

• Compacting and cementing
• Cooling 
• Heat and pressure
