Study Notes
Weathering
- Rocks on the Earth's surface are worn away by rain, water, wind, and other forces.
- Weathering changes the shape of rocks and creates smaller pieces.
- Plant roots can break rocks into smaller pieces.
- When water in a small crack freezes, it expands and causes the crack to widen.
Rock Formation
- A mushroom-shaped rock can form from sandstone, which is softer than the top, causing it to erode faster.
- Waves and wind can create arches in rocks.
- Slate and quartzite are metamorphic rocks.
Rock Types
- Shale is a sedimentary rock that changes into slate.
- Sandstone is a sedimentary rock that changes into quartzite.
Weathering
- Rocks on the Earth's surface are worn away by rain, wind, and moving water.
- Weathering changes the shape of rocks and breaks them into smaller pieces.
- Plant roots can also break rocks apart.
- Water in a small crack expands when it freezes, enlarging the crack.
Rock Features
- Some rocks are shaped like mushrooms due to weathering.
- These mushrooms are formed from sandstone, with the top being harder than the bottom.
- Waves and wind erode rocks, forming arches.
- Arched rock features can be composed of metamorphic rocks such as slate and quartzite.
Rock Transformations
- Shale, a sedimentary rock, transforms into slate under heat and pressure.
- Sandstone, another sedimentary rock, can transform into quartzite.
