Question

select the statement(s) that accurately describe metamorphic rock.
metamorphic rock is formed from the layering of sediments.
metamorphic rock is formed on the earths surface.
metamorphic rock is more compact and dense than other types of rock.
metamorphic rock is formed as a result of heat and pressure.
metamorphic rock is made from other types of rock.

Explanation:

1. Analyze each statement:

• "Metamorphic rock is formed from the layering of sediments." - Sedimentary rocks form from sediment layering, so this is incorrect.
• "Metamorphic rock is formed on the Earth's surface." - Metamorphism occurs under heat and pressure (usually deep within the Earth), so this is incorrect.
• "Metamorphic rock is more compact and dense than other types of rock." - Due to the heat and pressure during formation, metamorphic rocks are often more compact and dense than sedimentary (and sometimes igneous) rocks, so this is correct.
• "Metamorphic rock is formed as a result of heat and pressure." - By definition, metamorphic rocks form from existing rocks (protoliths) that are altered by heat, pressure, and/or chemical processes (metamorphism), so this is correct.
• "Metamorphic rock is made from other types of rock." - Metamorphic rocks are formed by altering existing rocks (igneous, sedimentary, or other metamorphic rocks) through metamorphism, so this is correct.

Answer:

• Metamorphic rock is more compact and dense than other types of rock.
• Metamorphic rock is formed as a result of heat and pressure.
• Metamorphic rock is made from other types of rock.
