Answer: c)
Glacier
does not cause erosion.
What are the 4 main causes of 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 of the following is not a possible cause of erosion?
Answer: c)
Glacier
does not cause erosion.
What are 3 causes of erosion?
The three main forces that cause erosion are
water, wind, and ice
. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.
What are the 5 things that cause erosion?
The agents of soil erosion are the same as of other types of erosion:
water, ice, wind, and gravity
. Soil erosion is more likely where the ground has been disturbed by agriculture, grazing animals, logging, mining, construction, and recreational activities.
What are the types of erosion?
- surface erosion.
- fluvial erosion.
- mass-movement erosion.
- streambank erosion.
Which is an example of natural erosion?
Rain, rivers, floods, lakes
, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
How can erosion be prevented?
Crop Rotation
: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.
What are the 6 agents of erosion?
Agents of erosion include
rainfall
; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows.
Which is the most effective agent of erosion?
Water
is the most efficient and effective agent for erosion. Erosion by water commonly occurs in two different geologic settings: 1. Coastlines – erosion that occurs on coastlines is due to the action of ocean currents, waves, and tides.
What are the two causes of erosion?
Erosion is caused by
wind, water, or gravity
.
What are the signs of erosion that you have observed?
- Exposed tree roots.
- Cracks in the soil in a river bank.
- Clumps of grass in the river.
- The top part of the river bank overhangs.
- Brown or coloured water.
- Collapsed river bank.
Which of the following is an example of erosion?
All of the following are examples of erosion EXCEPT:
The wind in the desert blows sand against a rock
. A glacier picks up boulders as it moves. A flood washes over a riverbank, and the water carries small soil particles downstream.
How do living conditions change as a result of erosion?
Answer: Excessive (or accelerated) erosion causes both “on-site” and “off-site” problems. On-site impacts include decreases in agricultural productivity and
(on natural landscapes) ecological collapse
, both because of loss of the nutrient-rich upper soil layers.
What are the 4 types of water erosion?
Despite its sometimes destructive nature, water erosion is a natural phenomenon that can literally shape our world in large ways. There are several different types of water erosion, but they can generally be grouped into four main types. These are
inter-rill erosion, rill erosion, gully erosion, and streambank erosion
.
