The Rock Cycle
Grade 6 · Science · Earth Processes · Vermont, USA
Lesson Summary
The rock cycle describes how rocks are constantly changing from one type to another through natural processes.
Explanation
There are three types of rock: igneous (formed from cooled magma or lava), sedimentary (formed from compressed layers of sediment), and metamorphic (formed when existing rocks are changed by heat and pressure). The rock cycle shows how these types transform into one another over time. For example, igneous rock can be weathered into sediment, which compresses into sedimentary rock, which can be heated and squeezed into metamorphic rock, which can melt and become igneous rock again. The cycle has no beginning or end and takes millions of years.
Practice Questions
Q1: What are the three types of rock?
Answer: Igneous, sedimentary, and metamorphic.
Q2: How does sedimentary rock form?
Answer: Layers of sediment, like sand and mud, are deposited over time and compressed together by the weight above them.
Q3: What force turns sedimentary rock into metamorphic rock?
Answer: Heat and pressure deep within the Earth change the structure of the rock without melting it.
