Erosion by rivers is faster because the processes carried out by rivers are far faster; for example, a river meander may move to the other side of the valley in a decade, yet a glacial trough may not widen by a single centimeter in the same time. However, you should also note that the landscapes caused by glaciers can form in a shorter period of time, and be far more impressive, but this is not the rule.
You will also notice that the features caused by glacial erosion are a lot cruder than those from rivers: compare the Grand Canyon and any glacial trough, the one I know best is Nant Ffrancon in Snowdonia, though I'm sure there's another near you. You can see that the Grand Canyon is far rougher, but also more intricate: there are stacks, as well as other features (as I am not particularly familiar with the Canyon). Nant Ffrancon, on the other hand it just a simple trough - a U-shaped valley. It is very different.
You may also note that glacial erosion is greatly affected by weathering. It was pointed out to me that one side of Nant Ffrancon was steeper than the other. This is as a result of the sun causing more melting of the ice on one side than the other. A river acts quickly and so is not nearly as affected by such factors, if at all affected.
Here are just a few comparisons between the two.
Erosion by rivers tends to be more gradual and focused on creating V-shaped valleys and meandering channels, while erosion by glaciers is more powerful and can carve out U-shaped valleys and create deep cirques and fjords. Glaciers also leave behind distinct landforms like moraines, drumlins, and eskers due to their ability to transport large amounts of debris. Overall, glaciers tend to be more effective at shaping the landscape over shorter periods compared to rivers.

What is most of the of the erosion on earth caused by?
Most erosion on Earth is caused by water, specifically from rivers, waves, and rainfall. Wind, glaciers, and human activities such as deforestation and construction also contribute to erosion.
What are three transporting agents of erosion?
Three transporting agents of erosion are water, wind, and ice. Water erosion is caused by rivers, streams, and rainfall, while wind erosion occurs in arid and windy environments. Ice erosion, known as glacial erosion, is caused by the movement of glaciers.
The three most common agents of erosion are .?
water, wind, and ice
What are the four agents of erosion?
The four agents of erosion are water, wind, ice, and gravity. Water erosion is caused by rivers, streams, and rainfall. Wind erosion occurs when wind carries and deposits sediment. Ice erosion is caused by glaciers moving and carving the land. Gravity erosion involves materials being pulled downhill due to gravity.
What is the major agent of erosion on Earths surface?
Water is the major agent of erosion on Earth's surface, with processes like rivers, streams, rainfall, and glaciers constantly shaping the land. Wind, glaciers, and gravity also contribute to erosion, but water is the most significant force.
How is erosion caused by rivers different than erosion caused by glaciers?
the cause by the change of the earth

What do rivers glaciers wind and waves cause?
Weathering and Erosion.

Can mountains cause erosion?
No, it is they that are eroded by such things as rain, rivers and glaciers.
What caused the valley to form?
Valleys can form through processes like erosion by rivers, glaciers, or tectonic activity. For example, rivers may erode the land over time, creating a valley. Glaciers can also carve out valleys as they move across the landscape. Tectonic processes like faulting or folding can create valleys as well.

What three types of erosion constantly reshaping the contours of our planet?
The three main types of erosion constantly reshaping the planet are water erosion, wind erosion, and glacier erosion. Water erosion, caused by rivers and rain, shapes landscapes through processes like river cutting and coastal erosion. Wind erosion occurs when wind carries and deposits sediment, shaping areas such as deserts and coastlines. Glacier erosion, caused by moving ice, carves valleys and fjords as glaciers advance and retreat.
What is a deep narrow valley with high steep sides caused by weathering and erosion?
A deep narrow valley with high steep sides caused by weathering and erosion is known as a canyon. Canyons are typically formed over long periods of time by the action of rivers, glaciers, or other natural forces cutting through the rock.
What are the forces that causes erosion?
Erosion can be caused by several forces, including water (rivers, rainfall, waves), wind, glaciers, and human activities like mining and construction. These forces can wear down rock and soil, carrying them away and reshaping the landscape over time.
