Answer 2

The correct statement is:

"Igneous, metamorphic, and sedimentary rocks can all become sediments after years of erosion."

This statement accurately reflects the rock cycle, where all types of rocks can break down into sediments through erosion processes.

Answer 3

The correct label the student should add to an arrow from the picture of obsidian (igneous rock) to the picture of slate (metamorphic rock) is:

**heat and pressure**

This indicates the process of metamorphism, where heat and pressure transform existing rocks, such as igneous rocks, into metamorphic rocks.
