Life of a Rock
Students are studying the rock cycle in science class. The rock cycle is driven by different forms of energy. Energy from the Sun drives processes such as weathering, erosion, and sedimentation. Energy from Earth's hot interior drives processes such as melting and crystallization. Rocks can originate from different processes, or be transformed into different types of rocks, depending on the environment. In order to better understand the process, students create a model of the rock cycle. Their model is shown.

The model titled 'The Rock Cycle' shows that a volcanic eruption leads to cooling lava, and cooling lava turns into igneous rock. Igneous rock points to a process labeled '1' near water, heat and pressure under the surface, and a process labeled '3' under the surface. Heat and pressure applied to igneous rock form metamorphic rock. Metamorphic rock undergoes melting, turning into molten rock, which turns into magma. Cooling and uplift turn magma into igneous rock. Igneous rock undergoes process 3 under the surface, turning into magma. Igneous rock undergoes process 1, leading to transport and deposition of sediments into water, which leads to burial, sedimentation, compaction, and cementing further under the water. This process leads to sedimentary rock. Sedimentary rock undergoes process 2, which turns into metamorphic rock. Sedimentary rock and metamorphic rock also undergo process 1.

A metamorphic rock that has a new mineral composition after being exposed to extreme heat and pressure is an example of a chemical change that occurs over a long period of time. Igneous rocks that are formed by cooled lava are an example of a physical change that occurs over a short period of time.
