The rock cycle is a fundamental concept in geology that describes how rocks change over time through various processes. It's like a recycling program for rocks! Sedimentary, igneous, and metamorphic rocks constantly transform from one type to another through weathering, erosion, heat, pressure, melting, and cooling. DIY rock cycle activities for middle schoolers bring these abstract concepts to life using household materials and simple experiments, making learning engaging and memorable.
Match the terms with their correct definitions:
| Term | Definition |
|---|---|
| 1. Igneous Rock | A. Rock formed from pre-existing rocks that are changed by heat, pressure, or chemical processes. |
| 2. Sedimentary Rock | B. The breaking down of rocks, soil, and minerals through contact with the Earth's atmosphere, waters, and biological organisms. |
| 3. Metamorphic Rock | C. Rock formed from the cooling and solidification of magma or lava. |
| 4. Weathering | D. The process by which sediments accumulate and compact into solid rock. |
| 5. Sedimentation | E. Rock formed from the accumulation and cementation of sediments. |
Answers:
Complete the paragraph using the words: magma, sediments, metamorphic, weathering, and erosion.
The rock cycle begins with molten rock called _______ deep beneath the Earth's surface. When this cools and solidifies, ________ rocks are formed. Rocks at the surface undergo _________ and _________, breaking them down into smaller pieces called __________. Over time, these can form ________ rocks. If any rock is subjected to extreme heat and pressure, it can become a ________ rock.
Answers:
