What is the process of glacier erosion?
Glaciers cause erosion in two main ways: plucking and abrasion. Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice. Abrasion is the process in which a glacier scrapes underlying rock.
What process carries rock away?
erosion
What is 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).
What is the process of deposition?
Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
What is a real life example of deposition?
The most typical example of deposition would be frost. Frost is the deposition of water vapour from humid air or air containing water vapour on to a solid surface. Solid frost is formed when a surface, for example a leaf, is at a temperature lower than the freezing point of water and the surrounding air is humid.
What are the examples of slow change?
Formation of rust takes longer time and is not an immediate reaction. Therefore, rusting of iron is an example of slow change where new substance, iron oxide is formed. 2. Another example of slow change is rotation of earth, which causes day to night.
What are fast changes to Earth’s surface?
Changes to Earth can happen suddenly or over long periods of time. Earthquakes, volcanoes, tsunamis and landslides are naturally occurring events that can rapidly change Earth’s surface.
What are slow and fast changes give examples?
Whereas slow changes take place very slowly and may take hours, days or months to complete. Examples for fast changes: Burning of paper, Burning of a candle. Examples for slow changes: Rusting of iron, Germination of seed, curdling of milk etc.
What is slow or fast change?
The changes that take a long duration of time to complete, are called slow changes. This duration can be in hours, days or even months. The changes that are completed in short or very short duration of time are called fast changes. Examples of slow changes: Rusting of iron, as it takes many days.
What are three examples of slow changes?
Some changes are fast and immediately observable, such as earthquakes, volcanoes, flooding, and landslides. Other changes are slower and occur over a longer period of time, such as weathering and erosion. These gradual processes shape landforms with water, ice, wind, living organisms, and gravity.
What is a slow change?
The changes which take place in a long period of time are called slow changes whereas, the changes which take place in a short period of time are called fast changes. Examples: (a) Rusting of iron, ripening of fruits, growing of trees are slow changes.
What are slow changes give two examples?
The changes happening over a long period of time are considered as slow changes. Example: Rusting of iron.
What is a sudden change give an example?
1.earthquake. 2.volcano. 3.tsunami. 4.change in atsmosphere (rainfall) 5.lightning/thunderstorm.
