abrasion and plucking
Rock can be worn down by physical and chemical weathering. One physical way can be seen at beaches. Rocks are worn down by the constant waves which propel abrasive materials against the rocks constantly. One chemical way is by acid rain. Rain is acidic because atmospheric carbon dioxide dissolves into the rain water.
Two ways glaciers move are through internal deformation, where ice crystals slip past each other due to pressure, and basal sliding, where the glacier slides on a thin layer of water at its base. These movements contribute to the overall flow of glaciers downhill.
There are 2 main types of glaciers, Continental is one, they float away from central regions. The second is alpine or valley which are the glaciers that flow down the valley from the mountain.
Glaciers remove Earth's surface through erosion, as they pick up and transport rocks and sediments. They build up Earth's surface by depositing these materials as they melt, forming landforms like moraines and drumlins.
These sharp ridges are called aretes and form when glacial erosion carves out valleys on either side of the ridge. As glaciers move down the valleys, they erode the rock on both sides, sharpening the ridge. Aretes are a common feature in glaciated regions like the Alps or Himalayas.
abrasion and plucking.
Glaciers are forces of erosion of the land they tend to do the opposite of build it up, they wear it down. However they do deposit moraines and when they melt the land springs up a little.
The two processes are abrasion and plucking.What processes lead to glacial erosion? Describe them.The two main processes that lead to glacial erosion are plucking and abrasion. Plucking is the process by which a glacier picks off rocks as it blocks over the land. The rock fragments freeze to the bottom of the glacier, gouging and scratching the bedrock as the glacier advances in the process of abrasion.

The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacail landforms. There are 2 main processes of erosion, plucking and abrasion. Plucking is where water melts under the glacier and carries rocks and other particles away. Abrasion is where rocks rub against surfaces changing the landform. For more info go to study.com/academy/lesson/glacial-erosion-definition-processes-features.html
Glaciers cover nearly 10% of Earth's land surface.
What is an Arete? An arete is very very thin piece of rock and very very sharp, which is almost always formed when 2 glaciers erode parrelel U-shaped valleys. Shruti

Waves erode approximately 1-2 feet of land from the coast of the US each year. This erosion can vary depending on factors such as the type of coastline, wave energy, and human interventions like seawalls.
2/3 of the earth is covered by glaciers
1. it was cold 2. it was very forestry (there were a lot of trees) 3. glaciers reshaped the land there
The two main types of glaciers are valley glaciers and continental glaciers. Valley glaciers, also known as alpine glaciers, form in mountainous regions and flow down through valleys, while continental glaciers, or ice sheets, cover vast areas of land and flow in all directions from their center. The key difference lies in their size and location: valley glaciers are smaller and confined to mountainous terrains, whereas continental glaciers are extensive, covering large portions of continents, such as Antarctica and Greenland. Both types are crucial in shaping landscapes and influencing global sea levels.
