* Weathering: The breakdown of rock due to exposure to elements like rain, wind, ice, and temperature changes.
* Erosion: The transportation of weathered material, often by water, wind, or ice.
Resistant rocks are those that are more durable and less susceptible to weathering and erosion. They are often made of harder minerals, like granite, sandstone, or quartzite.
How a resistant hill forms:
1. Differential erosion: When rivers flow through landscapes, they erode softer rocks more easily than harder rocks.
2. Resistant rock: As the river erodes the surrounding softer rock, the resistant rock remains standing, forming a hill.
3. Over time: The resistant hill becomes more prominent as the river continues to erode the surrounding area.
Examples:
* Monadnocks: Isolated hills of resistant rock that rise above a surrounding plain.
* Buttes: Similar to monadnocks but with steeper sides.
* Mesas: Flat-topped hills with a plateau-like top.
