Weathering
What is weathering?
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth.
What is erosion?
Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water
What are sediments?
Sediment is a naturally occurring material that is broken down by processes of weathering and erosion
What is depositition?
Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice.
What is mass wasting?
Mass wasting is the movement of rock and soil down slope under the influence of gravity.
What are some examples of physical weathering?
- Glaciers
- Actions of animals
-Plants growing
-Moving Water
What are some causes of erosion?
winds, hard rains, and flowing water.
Where do sediments come from?
Sediments come from weathered pieces of rocks.
What elements effect deposition?
What triggers mass wasting?
Mass wasting often occurs when something changes to cause a landslide at a specific time.
What are some examples of chemical weathering?
Examples include:
-Acid rain
-Iron oxide (Rust)
How can erosion effect the earths surface?
Erosion can form caves and arch's.
What can sediments form?
Sediments can form sedimentary rock through the process of lithification.
How can deposition effect the Earths surface?
Deposition can deposit bits of eroded soil and rock in one spot and eventually build up new land.
What is the major force of mass wasting?
Gravity is the main driving force behind mass-wasting processes
How do glaciers cause abrasion and weathering?
The ice at the bottom of a glacier is not clean but usually has bits of rock, sediment, and debris. It is rough, like sandpaper. As it flows down, sliding and flowing ice can weather the rock.
How does erosion work with weathering?
Weathering breaks down rocks while erosion moves and carry them away.
What are some ways sediments can be transported?
The main ways sediments can be moved include gravity,river and stream flows,ice,wind and ocean currants.
Where does deposition mostly occur?
Sediment deposition can be found anywhere in a water system, from high mountain streams, to rivers, lakes, deltas and floodplains.
What elements effect mass wasting?
Increased water, increased slope steepness, and earthquakes.
What are some causes of weathering?
Water, ice, acids, salts, plants, animals, and changes in temperature.
What are some everyday examples of erosion?
One example of erosion could be when it rains in my backyard, the rain carries the soil to the edge of my backyard near the fence and creates a huge mud puddle.
What are some real life examples of sedimentary rocks?
Some famous examples include the Grand Canyon.
why does deposition occur?
deposition may take place when a river enters an area with shallow water or when the volme of water decreases.
What are some examples of mass wasting?
Rock falls, slumps, and debris flows are all examples of mass wasting
