Abigail is making a cake by mixing flour, sugar, eggs, and baking it. How does this example illustrate the difference between rocks and minerals?

• The cake would be a mineral. The flour, sugar, and eggs would be rocks.

• The cake, flour, sugar, and eggs would all be rocks.

• The cake would be a rock. The flour, sugar, and eggs would be minerals.

• The cake, flour, sugar, and eggs would all be minerals.

Scarlett and Mia are on a geology field trip. Where should they search to find an igneous rock with small mineral crystals?

• Scarlett and Mia should search deep in the ground because smaller crystals form when magma cools slowly.

• Scarlett and Mia should search deep in the ground because smaller crystals form when magma heats quickly.

• Scarlett and Mia should search near the surface because smaller crystals form when magma cools quickly.

• Scarlett and Mia should search near the surface because smaller crystals form when magma heats slowly.

Which of the following pairs of rocks are both classified as sedimentary?

• sandstone and shale

• granite and basalt

• gneiss and marble

• slate and limestone

David and Zoe are studying rocks. What causes sedimentary rocks to become metamorphic rocks?

• weathering and erosion

• melting

• cooling

• heat and pressure

Mason and Avery are studying different types of rocks for their geology class. They learn that rocks are divided into igneous, sedimentary, or metamorphic groups based on their

• color and hardness.

• formation process.

• crystal structure.

• chemical composition.

During a school field trip to the beach, Daniel and Mia learned about the process that leads to the formation of sedimentary rock on the ocean floor. What process is this?

• Particles carried by rivers and winds settle on the ocean floor and gradually cement into sedimentary rock layers.

• High pressure and heat from the ocean's weight transform ocean floor material into sedimentary rock.

• Magma flows through ocean floor cracks and solidifies into sedimentary rock as it cools.

• Low temperatures cause ocean floor material to freeze and form sedimentary rock.

• intrusive sedimentary rock.

• extrusive igneous rock.

• intrusive igneous rock.
