Mrs. Martinez is teaching her class about how igneous rocks form from ash and other volcanic debris. Which of the following BEST describes how igneous rocks form?

• A. Deposition of sediments from the ocean

• B. Cooling of molten material

• C. Erosion of larger rocks

• D. Metamorphism of existing rocks

A student is studying data on lava flows and the igneous rocks they form after cooling. Which statement below correctly identifies the volcano that will likely have the larger crystals and why?

• Volcano A, because higher lava temperatures always produce larger crystals in the rock.

• Volcano B, because faster cooling rates result in larger crystals in the igneous rock.

• Volcano C, because slower cooling rates allow more time for larger crystals to form.

• Volcano D, because it has the greatest temperature.

During a classroom experiment, students melt a rock sample and then allow it to cool and solidify. The resulting rock is similar to the ones that form deep below the Earth's surface or from volcanic activity.

Which type of rock is likely formed from cooling lava?

• Sedimentary rock

• Metamorphic rock

• Igneous rock

• Mineral rock

How do the formation processes for the three types of rocks differ from one another?

• The processes for creating igneous rocks include the settling of sediment particles and formation underwater.

• Each type of rock undergoes unique formation processes, distinguishing it from the others.

• Metamorphic rocks are formed by processes identical to those of igneous rocks but at lower temperatures.

• The processes for sedimentary rock formation involve the application of intense heat and pressure over long periods.

Which characteristics provide evidence that this granite formed from slowly cooling magma? Select TWO correct answers.

• A. Large, visible crystals

• B. Layered structure

• C. Interlocking crystal structure

• D. Presence of fossils

• E. Glassy texture

A student finds a rock in the playground. What type of rock might this be?

• Igneous rock

• Sedimentary rock

• Metamorphic rock

• Mineral rock
