Question
Rock Cycle
The rock cycle is the way that rocks on Earth change from one type of rock to another.
The three types of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form when rock that has been melted to form liquid magma is cooled again. Sedimentary rocks form from small particles of rock that have been pressed tightly together. Metamorphic rocks form underground from heat and pressure. Processes that contribute to the rock cycle can occur quickly or take a very long time.
The model shows the rock cycle.
The rock cycle shows how energy from Earth contributes to metamorphic rock melting. The magma rises up through the volcano where it cools, creating igneous rock. The Sun's energy makes wind and water move. Wind and water cause weathering and erosion. Gravity causes landslides. These processes turn igneous rock into sediment, which settles in water. The sediment turns into sedimentary rock. Sedimentary rock undergoes heat and pressure, which turn it into metamorphic rock.

The scientist most likely found an igneous rock, such as obsidian, which is smooth and glassy in appearance. This type of rock forms when molten magma cools rapidly, often due to volcanic activity, without allowing crystals to grow. The rapid cooling results in a glass-like texture, giving the rock its characteristic smooth surface.
