Because it is so big and bulky.
It's heavy, it moves, it grinds.
Gravity.
A river of ice is a glacier.
When soil and rocks are added to the sides and bottom of a glacier, they become incorporated into the glacier as it moves. This process, known as glacial abrasion, allows the glacier to effectively erode the underlying bedrock as it advances. The frozen water in the glacier acts as a powerful agent, facilitating the grinding and smoothing of the rocks and soil it comes into contact with.
Glaciers are the agent of erosion that deposit irregular mounds of unsorted sediment with parallel scratches on rounded particles. This type of deposit is called a moraine, which is formed as the glacier moves and carries a mixture of different-sized sediments that get deposited when the glacier melts.
Yes, ice is a powerful agent of erosion and is considered to be one of the top agents of erosion in certain environments. It plays a crucial role in shaping landscapes through processes like freeze-thaw cycles and glacial movement. However, the ranking of ice as the 3rd most powerful agent of erosion may vary depending on the specific geological context being considered.
Glaciers, while geographically restricted, are effective agents of landscape change. The gradual movement of ice down a valley causes abrasion and plucking of the underlying rock. Abrasion produces fine sediment, termed glacial flour. The debris transported by the glacier, when the glacier recedes, is termed a moraine. Glacial erosion is responsible for U-shaped valleys, as opposed to the V-shaped valleys of fluvial origin. Running water is the most effective agent of erosion on the earth, giant blocks of ice are lots of water.
Yes. Look at any glacial (u-shaped) valley and the terminal moraine at the end where the glacier melts.
Water is the predominant agent of erosion on Earth, shaping landscapes through processes like river erosion, coastal erosion, and weathering. Its ability to transport sediment and wear down rock over time make it a powerful force in shaping the Earth's surface.
Wind is the weakest agent of erosion.
The agent of erosion on cliffs mostly is gravity.
Gravity induced moving water is the most effective agent of erosion.
