What are two ways in which glaciers erode earth's suface?
Glaciers erode Earth's surface through abrasion, where the ice and sediments grind against the rock, wearing it down. They also erode through plucking, where the glacier freezes onto rock and plucks or pulls it away as the glacier moves.
How do glacier erode by abrasion?
Glaciers erode by abrasion as they move over the landscape, dragging along rocks and sediment that are embedded in their ice. This process occurs when the weight and pressure of the glacier cause these materials to grind against the underlying bedrock, effectively wearing it down over time. The friction generated by this movement can create striations and grooves in the rock surface, shaping the landscape and contributing to the glacial sculpting of valleys and other geological features. Ultimately, abrasion is a key mechanism of glacial erosion, contributing to the overall alteration of the terrain.
Streams erode their channels by abrasion by dissolving soluble material and by?
Streams erode their channels through processes such as hydraulic action, where the force of water removes soil and rock, and through the impact of sediment and debris carried by the water, which grind against the channel surfaces. Additionally, streams can erode by undercutting banks, leading to collapse and further widening of the channel. Together, these processes shape the landscape and contribute to the ongoing evolution of river systems.
What is it called when particles in a river wear each other down?
The process in which particles in a river wear each other down is called "abrasion." As sediment and rocks are transported by the flowing water, they collide and grind against each other, resulting in the smoothing and rounding of their edges. This process contributes to the overall erosion and shaping of the riverbed and surrounding landscape.
How does a glacier create smooth rocks with striations?
Glaciers create smooth rocks with striations through a process called glacial abrasion. As glaciers move, they carry debris and sediment that grind against the underlying bedrock, polishing the surfaces of rocks and smoothing them out. The striations, or scratches, are formed by larger stones embedded in the glacier that scrape across the rock surface, leaving distinctive grooves. This combination of abrasion and scratching results in the characteristic smoothness and striated patterns observed on glacially-formed rocks.
What is 2 ways that glaciers erode the land?
Glaciers erode the land through plucking, where they pick up and remove rock fragments as they move, and abrasion, where they scrape and grind the underlying bedrock as they advance. These processes help to shape landforms such as valleys, cirques, and moraines.
What processes lead to glacial erosion Describe them.?
Glacial erosion occurs primarily through the processes of plucking and abrasion. Plucking happens when the glacier picks up rocks and sediments as it moves, while abrasion occurs when these materials scrape and grind against the rock surface, wearing it down. Together, these processes shape the landscape by carving out valleys, creating deep basins, and smoothing the underlying bedrock.
How does a glacier accomplish erosion?
The glacier is melting on the mountain and underneath it is like a river which eroding a side of the mountain when the glacier melts enough, it will slide down the mountain and into the lake that the river underneath the glacier had created. Hope this helps :)

Waves cause erosion by impact and what?
Waves cause erosion through impact by carrying sediments and smashing them against the coast. They also erode through abrasion, where sediments carried by waves grind against the coast, wearing it down over time.
What is it called when rocks grind against each other?
When rocks grind against each other, it is called "abrasion." This process occurs when rocks are carried by wind, water, or glaciers, causing them to collide and wear down over time. Abrasion is one of the key processes responsible for the erosion and shaping of Earth's surface.

How do wind and glaciers compare and contrast when it comes to abrasion of rocks?
Wind abrasion occurs in dry and arid environments where particles carried by the wind wear down rock surfaces through impact. Glacial abrasion, on the other hand, happens in icy environments where glaciers grind against rock surfaces as they move, causing striations and polishing. Both processes involve the physical wearing down of rocks, but wind abrasion is typically more widespread and affects smaller particles, while glacial abrasion is more localized and can leave distinct marks.
What physical weathering process do glaciers contribute?
Glaciers contribute to physical weathering through a process called abrasion, where the movement of ice and rock fragments scours and erodes the underlying bedrock. As glaciers move, they pick up and carry large boulders and rocks that act as tools to grind and shape the landscape beneath them. Over time, this process can create valleys, fjords, and other glacier-carved landforms.
