What are thick masses of ice that erode rock and move sediment called?
These are glaciers.
How do glaciers accumulate their load of sediment?
Glaciers accumulate sediment through various processes. As glaciers move, they pluck and erode rocks from the underlying bedrock, entraining them into the ice. Glaciers also grind and crush the rocks they come into contact with, generating glacial flour or fine-grained sediment. Additionally, glaciers can transport sediment that has been deposited on their surface by wind or landslides, adding to their load of sediment.
Is glacial ice a sediment transporting agent?
Yes, glacial ice is a significant sediment transporting agent. As glaciers move, they can erode the underlying rock and soil, picking up sediments of various sizes, from fine silt to large boulders. When glaciers advance or retreat, they deposit these sediments, creating landforms such as moraines and outwash plains. Thus, glacial ice plays a crucial role in shaping landscapes and redistributing materials over large distances.
What must any rock in the rock cycle do to become a sedimentary rock?
It must erode into sediment and then be compressed to form sedimentary rock.
Why are glaciers the most erosive force in nature?
Glaciers are the most erosive force in nature due to their ability to transport vast amounts of rock and sediment across the landscape as they move. The immense weight and pressure exerted by glaciers can pluck, scrape, and grind rocks, creating deep valleys, sharp peaks, and U-shaped valleys. Additionally, the meltwater from glaciers can further erode the land by carrying sediment and debris downstream, shaping the landscape over time.

How does nature erode and and deposit rock?
Water erodes small rocks by flowing over them,, ice glaciers drag rocks with them.

How do glaciers and rivers make new rock types?
Glaciers and rivers can erode existing rocks to create sediment. Over time, this sediment can be compacted and cemented together to form new sedimentary rocks. In addition, heat and pressure from tectonic processes can metamorphose existing rocks into new rock types.
Why is weathering important to the rock cycle?
If there is no weather on earth we might not be able to live. weather also brings us food by giving us rain for our crops.
How does gravity relate to a stream's ability to erode and deposit materials?
Gravity influences a stream's ability to erode materials by pulling them downstream. The force of gravity helps water to carry sediment and erode the streambed. Additionally, gravity plays a role in the deposition of materials by causing sediment to settle out of the water when the stream's velocity decreases.
What must any rock in the rock cycle do to become a sedimentary rock?
It must erode into sediment and then be compressed to form sedimentary rock.
How does glaciers and rivers form new rocks?
Glaciers and rivers transport eroded rock material (sediment), that can form new sedimentary rock after deposition.
Why are glaciers the most erosive force in nature?
Glaciers are the most erosive force in nature due to their ability to transport vast amounts of rock and sediment across the landscape as they move. The immense weight and pressure exerted by glaciers can pluck, scrape, and grind rocks, creating deep valleys, sharp peaks, and U-shaped valleys. Additionally, the meltwater from glaciers can further erode the land by carrying sediment and debris downstream, shaping the landscape over time.
Can a sedimentary rock turn back into a deposit of sediment?
Yes! The process of weathering can "break down" a sedimentary rock and turn it back into a sediment.
How do glaciers erode rock?
Glaciers erode rock through processes like plucking and abrasion. Plucking involves the freezing of water within cracks in the rock, causing pieces of rock to be pulled out as the glacier moves. Abrasion occurs when the glacier carries rocks and debris that scrape against the rock surface, wearing it down over time.
Do glaciers cause water erosion?
Glaciers cause erosion because of the immense weight and pressure they can exude onto surfaces. Fine grains of sediment get lodged into the bottom and sides of the glacier, making it so abrasive that it scratches grooves into rock as it moves.
