What process is the cause of ground water erosion?
The process that causes groundwater erosion is chemical weathering.
What type of weathering causes groundwater erosion?
Groundwater can cause erosion through a process called chemical weathering. This process is the process when water sinks into the ground, combines with carbon dioxide, and the becomes a weak acid, called carbonic acid. Carbonic acid can break down limestone.
How does groundwater cause deposition?
As water flows through the soil, acid is formed. This acid can cause minerals to be dissolved. Minerals that are carried in groundwater can also be deposited in other places. This cycle of erosion and deposition can cause underground caves to form.
How does groundwater erosion and deposition produce a limestone cave?
Groundwater erosion and deposition produce a limestone cave when water containing carbonic acid and calcium from limestone drips from a cave's roof. Carbon dioxide is released from the solution leaving behind a deposit of calcite.
Does groundwater cause erosion and deposition?
In this post, we are dealing with the geomorphic agents – running water and groundwater, which causes erosion and deposition. They form various erosional (destructional) and depositional (constructional) landforms.
What do mean by water erosion and its process?
Water erosion is the detachment and removal of soil material by water. The process may be natural or accelerated by human activity. The rate of erosion may be very slow to very rapid, depending on the soil, the local landscape, and weather conditions. Water erosion wears away the earth's surface.
What is underground erosion?
Groundwater Erosion It seeps through cracks in rock. The water moves slowly, pulled deeper and deeper by gravity. Water in an underground rock or sediment layer is groundwater. Underground water can also erode and deposit material. Rainwater absorbs carbon dioxide (CO2) as it falls.
What is erosional work of groundwater?
Groundwater moves through minor cracks slowly over many years. The water dissolves the solid rock and transports it away, gradually widening the cracks and eventually forming a cave. The dissolved minerals in the solution are carried by groundwater. This process is termed groundwater erosion.
What is groundwater deposition?
Groundwater dissolves minerals and rocks into ions. Groundwater deposits those ions into different types of structures. Limestone caves are the best place to see these structures. Water erodes the cave, and the deposits form structures like stalactites and stalagmites.
What is erosion deposition?
Erosion – The process of moving rocks and soil downhill or into streams, rivers, or oceans. • Deposition – The accumulation or laying down of matter by a natural process, as in the laying down of sediments in streams or rivers.
What is the process of soil erosion?
Soil erosion can occur in two stages: 1) detachment of soil particles by raindrop impact, splash, or flowing water; and 2) transport of detached particles by splash or flowing water. Therefore, soil erosion is a physical process requiring energy, and its control requires certain measures to dissipate this energy.
What are the causes of erosion?
Four Causes of Soil Erosion
- Water. Water is the most common cause of soil erosion. …
- Wind. Wind can also make soil erode by displacing it. …
- Ice. We don't get much ice here in Lawrenceville, GA, but for those that do, the concept is the same as water. …
- Gravity. Gravity is a primary culprit behind the three other causes.

Which type of process causes erosion internal or external?
Answer: 1) External processes shape the relief created by internal processes. External agents carry out this process: water, ice, wind, atmosphere and human beings. They include all the changes that alter or wear down the rocks and deposit materials resulting from erosion.
Which features are created by groundwater erosion and deposition?
Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns.
What is formed due to erosion?
Rocks eroded through physical erosion often form clastic sediments. Clastic sediments are composed of fragments of older rocks that have been transported from their place of origin. Landslides and other forms of mass wasting are associated with physical weathering.
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.
What is the process of weathering erosion and deposition?
After pieces of the Earth are broken down through weathering, those pieces are moved through erosion. It's the process of moving things from one place to another. Deposition. After pieces of the Earth are carried by erosion they are deposited somewhere else. Deposition means to deposit things somewhere else.
What are the 4 processes of erosion?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition. Image credit: Jeff Hansen, U.S. Geological Survey. Hydraulic Action is the sheer force of water crashing against the coastline causing material to be dislodged and carried away by the sea.
Which is created through the process of erosion?
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.
What is internal process and external process?
External processes. (i) The forces that act from the Earth's interior toward the Earth's surface are called Internal processes. The forces that act on the surface of the Earth due to natural agents like running water, glacier, wind, waves etc., are called External processes.
What causes deposition?
Deposition occurs when the eroding agent, whether it be gravity, ice, water, waves or wind, runs out of energy and can no longer carry its load of eroded material. The energy available to the erosion agents comes from gravity, or in the case of wind, the Sun.
What is landform process?
Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time, sometimes millions of years.
What are the two processes of erosion?
Two main processes are responsible for this; erosion and deposition. Coastal erosion is the breaking down and carrying away of materials by the sea. Deposition is when material carried by the sea is deposited or left behind on the coast. Coastal erosion takes place with destructive waves.
What causes erosion and deposition?
Water flowing over Earth's surface or underground causes erosion and deposition. Water flowing over a steeper slope moves faster and causes more erosion. How water transports particles depends on their size. When water slows down, it starts depositing sediment, starting with the largest particles first.
What is process of river erosion?
Processes of a river. Erosion There are four ways that a river erodes; hydraulic action, corrosion, corrosion and attrition.
What does the process of erosion and deposition create?
The process of erosion and deposition create different landforms on the surface of the earth.
What is the external process?
External Processes (or) Exogenetic Processes The forces that act on the surface of the earth due to natural agents like running water, glacier, wind, waves, etc., are called External processes or Exogenetic processes. These external processes tear the landscape down into relatively low elevated plains.
What is called external process?
External Process: Continuous wearing down and rebuilding of the earth's surface is the result of external process. Erosion: Removal of materials is called erosion. Erosion results in lowering of the earth's surface. Erosion is carried out by various agents; like wind and water.
What is the process of erosion and deposition?
Erosion is when materials, like soil or rocks, are moved by wind or water. All these materials are called sediments. Deposition is when those sediments are deposited, or dropped off, in a different location. These processes change the way the surface of the earth looks over time.
What is external process?
