Question 112 pts
Taylor created the following table to compare the three types of rock. What correction needs to be made to the information in the table?

Rock Type Igneous Rock Metamorphic Rock Sedimentary Rock
Formation Cooling and hardening of sediment High heat and pressure cause chemical change Made of lava cemented together
Examples Granite, Basalt Marble, Gneiss Sandstone, Limestone
Group of answer choices

Examples of igneous rock are sandstone and limestone, and examples of sedimentary rock are granite and basalt.

Metamorphic rock forms from the cooling and hardening of sediment, and igneous rock is made from high heat and pressure, causing chemical change.

Examples of igneous rock are granite and marble, and examples of metamorphic rock are basalt and gneiss.

Igneous rocks form from the cooling and hardening of magma or lava, and sedimentary rock is made of sediment cemented together.
