IGCSE ENVIRONMENTAL MANAGEMENT ROCK CYCLE PPT
- 2. Starter: listen to this rap song • https://youtu.be/EAgBlSotSB4 Task 1: What is a rock cycle?
- 3. Learning Objective •Describe and interpret the rock cycle Keywords 1. Metamorphic 2. Igneous 3. Sedimentary 4. Rock cycle
- 4. Cross-match activity Metamorphic rocks form from the cooling and solidification of magma or lava Igneous rocks form from the accumulation and lithification of sediments (fragments of other rocks, minerals, and organic material). Sedimentary form from existing rocks (igneous, sedimentary, or other metamorphic rocks) that undergo transformation due to intense heat, pressure, and/or chemically active fluids. Rock cycle The rock cycle describes the processes through which the three main rock types (igneous, metamorphic, and sedimentary) transform from one type into another. Learning objective: Describe and interpret the rock cycle
- 5. Task 2: Card sorting: separate the cards into processes involve in the formation of igneous, sedimentary and metamorphic rocks Learning objective: Describe and interpret the rock cycle
- 6. Check if you answers are correct Group 1: Igneous group Melting: Rocks (sedimentary and metamorphic rock) in the Earth's mantle or crust melt due to high temperatures and pressures, forming magma. Cooling and solidification: When magma rises towards the surface or erupts from a volcano, it cools and solidifies to for igneous rock. Group 2: sedimentary group Process • Weathering and erosion: Rocks on the Earth's surface are broken down into smaller particles by weathering (physical and chemical). • Transportation and deposition: Sediments are transported by wind, water, or ice to new locations and accumulate in layers. • Compaction and Cementation: Over time, layers of sediments are buried, compacted and cemented to form sedimentary rock. Group 3: metamorphic group Heat and Pressure: High temperatures, typically from nearby magma or deep burial, cause minerals in the rock to recrystallize it without melting to form Metamorphic rock. Chemical Activity: Fluids can introduce new minerals or facilitate the growth of existing minerals, altering the rock's composition and structure. Learning objective: Describe and interpret the rock cycle
