Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in
temperature
are all agents of weathering and erosion.
Which term describes weathering?
Weathering is a term which describes
the general process by which rocks are broken down
at the Earth’s surface into such things as sediments, clays, soils and substances that are dissolved in water. … As weathered products are carried away, fresh rocks are exposed to further weathering.
What best describes the process of erosion?
Erosion is the
geological process in which earthen materials are worn away and transported by natural forces such as wind or water
. A similar process, weathering, breaks down or dissolves rock, but does not involve movement. … Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier).
Which describes how weathering and erosion are different?
Erosion and weathering are
the processes in which the rocks are broken down into fine particles
. Erosion is the process in which rock particles are carried away by wind and water. Weathering, on the other hand, degrades the rocks without displacing them.
What are 2 types of erosion?
- surface erosion.
- fluvial erosion.
- mass-movement erosion.
- streambank erosion.
What is an example of erosion?
Erosion is the movement of particles away from their source. Example of erosion:
Wind carries small pieces of rock away from the side of a mountain
. Chemical Weathering: – Decomposition of rock and soil due to chemical reactions.
What are some examples of physical weathering?
- Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. …
- Ice wedging. Ice wedging causes many rocks to break. …
- Plant roots. Plant roots can grow in cracks.
What are 4 factors that affect weathering?
- rock strength/hardness.
- mineral and chemical composition.
- colour.
- rock texture.
- rock structure.
What is weathering and its types?
Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. … There are three types of
weathering, physical, chemical and biological
.
What are the similarities and differences between weathering and erosion?
| Erosion Weathering | The eroded materials are displaced. The weathered materials are not displaced. | The different types of erosion are water, wind, ice, thermal and gravity erosion The different types of weathering include physical, chemical and biological weathering |
|---|
What do weathering and erosion have in common?
Both weathering and erosion are processes that
wear away rocks
. These two processes collaborate to break down rocks by removing or forcing out particles and sediment. Water is a force that helps both processes to occur.
What are 2 types of weathering?
Weathering is often divided into the processes of
mechanical weathering and chemical weathering
. Biological weathering, in which living or once-living organisms contribute to weathering, can be a part of both processes.
What are the six causes of erosion?
- Soil Texture: ADVERTISEMENTS: …
- Ground Slope: …
- Intensity and amount of rainfall: …
- Mismanaged utilization of soil resources: …
- Distribution of rainfall and landscape: …
- Deforestation:
What are the 4 erosion processes?
The material that is deposited by constructive waves can most often be seen by the creation of beaches. Destructive waves erode through four main processes;
Hydraulic Action, Compression, Abrasion and Attrition

What are the 4 types of river erosion?
- Hydraulic action – This is the sheer power of the water as it smashes against the river banks. …
- Abrasion – When pebbles grind along the river bank and bed in a sand-papering effect.
- Attrition – When rocks that the river is carrying knock against each other.
What are three examples of erosion?
- Caves. Caves are carved out over thousands of years by flowing water, but that activity can be sped up by carbonic acid present in the water. …
- River Banks. …
- Cracks in Rocks. …
- Gravitation Erosion. …
- Coastal Erosion.
