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 is the strongest force of erosion?
Given enough time, water and ice can even cut through solid rock. But the most powerful force behind erosion is gravity. Gravity causes chunks of rock to fall from mountains and pulls glaciers downhill, cutting through solid stone.
What is the number one cause of erosion?
Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.
What is the weakest type of erosion?
Erosion by wind
Wind erosion occurs when wind moves pieces of earth materials. Wind erosion is one of the weakest kinds of erosion. Small pieces of earth material can be rolled along the ground surface by wind. Very small pieces can be picked up and carried by the wind.
What is the weakest agent of erosion?
Wind by itself is the weakest agent of erosion.
What are 3 things that can cause 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 5 causes of erosion?
5 Common Causes of Soil Erosion
- Water. Water is very effective at doing work. …
- Wind. Although wind usually erodes soil more slowly than water, Florida does have an active hurricane season from June to November. …
- Gravity. When thinking about soil erosion, gravity often worked in conjunction with water and wind. …

What are the 5 things that cause erosion?
Terms in this set (5)
- Temperature. rock expands with hot temperature and contracts with cold ones. …
- Ice. when water freezes in the cracks of the rocks it expands, causing small pieces to break off. …
- Wind. wind action carries away small rock particles of the rock surface. …
- Vegetation. …
- Running Water.
What are 4 types of erosion?
The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks.
What are the 4 types of water erosion?
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. Inter-rill erosion, also known as raindrop erosion, is the movement of soil by rainfall and its resulting surface flow.
What are the 4 types of soil erosion?
Rainfall and surface runoff
Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully 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.
Is gravity an agent of erosion?
Gravity can cause erosion and deposition. Gravity makes water and ice move. It also causes rock, soil, snow, or other material to move downhill in a process called mass movement. Particles in a steep sand pile move downhill.
How do human activities affect the rate of erosion?
Firstly the removal of trees is a removal of nutrients and minerals from the soil as the source of humus is greatly reduced. … Overgrazing, over cropping and or deforestation can lead to desertification – the spread of desert like lands due to these human activities accelerating natural erosion of soil.
