As glaciers pass over land they erode it, changing its features. Rocks frozen in the glaciers scrape across the bedrock, wearing it downand making scratches called striations. Eroded sediments get pushed in front of a glacierand piled up along its sides. These are called moraines. When glaciers begin to melt and retreat, the meltwater forms channels and deposites. Sediment in new locations. Large rocks called erratics can be left behind, many kilometersfrom their source.

How do glaciers contribute to the process of erosion?
Glaciers contribute to erosion by plucking and abrasion. Plucking occurs when glaciers pick up rocks and materials as they move, while abrasion happens when these materials scrape and carve the underlying rock, gradually wearing it down. As glaciers flow, they also erode the landscape by bulldozing and pushing material along their path.
Glaciers weather and water shape Earth by .?
Glaciers shape Earth by eroding rocks and forming valleys, lakes, and fjords through the process of glaciation. The ice movement, melting, and refreezing of glaciers contribute to the shaping of landscapes and the redistribution of sediments. Additionally, the water released from melting glaciers can create rivers, provide freshwater sources, and contribute to changes in the Earth's hydrological cycle.
Why do glaciers matter in terms of their impact on the environment and global climate change?
Glaciers are important because they store a significant amount of Earth's freshwater, which affects global sea levels and water availability. As glaciers melt due to climate change, they contribute to rising sea levels and can disrupt ecosystems and water supplies. Additionally, the reflective surface of glaciers helps regulate Earth's temperature by reflecting sunlight, so their loss can contribute to further warming.
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.
Do glaciers affect mountains?
Yes, glaciers can profoundly shape mountains through the processes of erosion, transportation, and deposition of sediments. Glaciers carve out U-shaped valleys, create cirques and aretes, and deposit moraines, all of which contribute to the unique features of mountain landscapes. Additionally, the weight of glaciers can cause the Earth's crust to bend and uplift, influencing mountain formation.
How did glaciers contribute to the formation of hills around the Lake Michigan?
As the glaciers retreated, they left rocks and boulders behind.

What are the pros of living near glaciers?
Living near glaciers can provide access to a valuable source of freshwater, as glaciers store a significant amount of the world's freshwater resources. Glaciers also contribute to unique ecosystems and biodiversity, supporting a variety of plant and animal species. Additionally, glaciers can attract tourists and researchers, boosting local economies and providing opportunities for scientific study and exploration.
Why are there no glaciers in Mississippi?
Mississippi's climate is too warm for glaciers to form and persist. Glaciers require very cold temperatures and consistent snow accumulation, which is not typically found in Mississippi due to its subtropical climate. Additionally, the state's low elevation and lack of suitable topography also contribute to the absence of glaciers.
What is the suffix for sedimentation?
The suffix for sedimentation is "-tion."

What will happen when glaciers in Himalayas melts?
Melting glaciers in the Himalayas will lead to an increase in water flow initially, causing immediate floods and eventual water scarcity as the glaciers continue to deplete. This will impact freshwater availability for millions of people who rely on these glaciers for their water supply. Additionally, the melting glaciers will contribute to sea-level rise, threatening coastal areas worldwide.
