15 Questions
What is weathering?
The breakdown of larger rock fragments into smaller particles
What is erosion?
The transportation of smaller particles to a new site by water, wind, or ice
What is deposition?
The accumulation of debris and smaller particles in a new place
Which process leads to the formation of sediments?
Weathering
What are the common transporting mediums for erosion?
Water, wind, and ice
What depositional landform is formed when a river overflows and deposits materials adjacent to the river?
Floodplains
Which depositional landform is created by the deposition and accumulation of sands carried by strong winds in the desert region?
Sand dunes
What type of moraine is formed when a thick mass of glacier moves over a region and leaves unconsolidated, loose accumulated materials as it recedes?
Terminal moraine
What depositional landform is known as the mouth of a river, where the river deposits all its sediments before flowing into the seas and oceans?
Deltas
What depositional landform is formed when moving glaciers carry sand and gravel size particles to a comparatively low-lying area where the glaciers melt, leaving only the accumulated materials?
Eskers
Which process involves slowly breaking down rocks through plant and animal activities?
Biological weathering
What landforms are created by water erosion?
Valleys
Which agent of erosion forms sea cliffs, sea arches, and sea stacks along coastal areas?
Water
What determines the rate of erosion?
The availability of wind and water
Which process involves the transportation of sediments to new locations?
Erosion
Study Notes
Weathering and Erosion: Key Processes and Landforms
- Physical weathering processes include freeze and thaw method, exfoliation, and abrasion.
- Chemical weathering processes involve hydrolysis, oxidation, and acid rain weathering.
- Biological weathering is caused by plant and animal activities, slowly breaking down rocks.
- Weathering and erosion constantly shape the Earth's surface, forming a variety of landforms.
- Fluvial erosion creates river valleys, oxbow lakes, waterfalls, sinkholes, and caves.
- Wind erosion forms landforms such as inselbergs, mushroom rocks, and pediplains.
- Water erosion creates valleys, canyons, waterfalls, ox-bow lakes, and ripple marks.
- Waves create sea cliffs, sea arches, and sea stacks along coastal areas.
- Erosion, caused by wind, water, and glaciers, transports sediments to new locations.
- The rate of erosion depends on the environment, availability of wind, water, and climate.
- Erosion changes the landscape over thousands to millions of years, making it a slow process.
- Wind, water, glaciers, waves, and gravity are the main agents of erosion, each affecting rock bodies differently.
