The bowl-shaped hollow from which alpine glaciers originate is called a "cirque." Formed by the processes of erosion and weathering, a cirque is typically situated on the side of a mountain and is characterized by steep walls and a flat bottom. As snow accumulates in this hollow, it compacts into ice, eventually leading to glacial movement down the mountainside. Cirques play a crucial role in the development of alpine glaciers and the surrounding landscape.

What is the bowl-shaped hollow from which alpine glaciers originate?
The bowl-shaped hollow from which alpine glaciers originate is called a cirque. Cirques are formed through the erosive action of ice and snow as they accumulate and flow down mountain slopes, carving out a steep, amphitheater-like depression. These features are typically located at high elevations and serve as the initial site for glacier formation before the ice moves downhill into valleys.
What is a type of Alpine glacier?
One type of Alpine glacier is a cirque glacier, which forms in a bowl-shaped depression on the side of a mountain. These glaciers are typically small and may be found at the head of a valley or on a mountainside.
Bowl shaped depressions in bedrock in upstream ends of alpine glacial valleys are called what?
Cirques. They are the bowl-shaped depressions formed by the erosion of glaciers in the upper parts of alpine valleys.
How do you describe the landscape made by alpine glaciers compared to the landscape by continental glaciers?
Alpine glaciers leave behind U-shaped valleys, deep, high-altitude lakes and cliffs. Continental glaciers flow outwards scraping the landscape clean, making fairly flat lands and lakes
What are sharp pyramid shaped peaks formed by alpine glaciers called?
Sharp pyramid-shaped peaks formed by alpine glaciers are called "horns." These features occur when multiple glaciers erode a mountain from different sides, creating steep, pointed summits. The most famous example is the Matterhorn in the Swiss Alps. Horns are typically characterized by their rugged, jagged profiles, resulting from the intense glacial activity.

Why do continental glaciers smooth the landscape and alpine glaciers create ragged landscape?
I only know that alpine glaciers can carve deep u-shaped valleys in the mountains.
What type of glaciers are sharp pyramid shaped and peaks formed by alpine glaciers?
Sharp pyramid-shaped peaks formed by alpine glaciers are called horn glaciers. Horn glaciers are created when three or more cirque glaciers erode a mountain from different sides, leaving behind a sharp-edged peak. Famous examples include the Matterhorn in the Alps.

How can alpine glaciers create these features?
Alpine glaciers create distinctive features through processes of erosion and deposition. As glaciers move down mountainous terrain, they carve out U-shaped valleys and sharp peaks, known as horns, through abrasion and plucking of rock. Additionally, when glaciers melt, they deposit sediment in the form of moraines, which are ridges of debris left at the glacier's edge. These processes collectively shape the dramatic landscapes characteristic of alpine environments.
How do alpine glaciers form?
Alpine glaciers form when snow accumulates in a mountain valley and compacts over time into ice. The weight of the ice causes it to flow downhill, carving out the valley and creating a glacier. Cold temperatures and consistent snowfall are necessary to sustain an alpine glacier.
What cross valley profile is typical of canyons and valleys eroded and deepened by alpine or valley glaciers?
The choices for this question are either a: U cross-Valley Profile, Y Cross-Valley Profile, V cross-valley profile, or S Cross Valley Profile.The answer to this question is a: U cross-valley profile is typical of canyons and valleys eroded by alpine or valley glaciers.
What glaciers create cirques on sides of mountains?
Glaciers that create cirques on the sides of mountains are called cirque glaciers. These glaciers form in bowl-shaped depressions on the slopes of mountains and are responsible for eroding and shaping the characteristic amphitheater-like features known as cirques. Examples of cirque glaciers can be found in mountain ranges around the world, such as the Alps, Andes, and Himalayas.
What are some differences in how these two types of glaciers affect the land?
There are two primary types of glaciers: alpine glaciers and continental glaciers. Alpine glaciers, found in mountainous regions, carve sharp peaks and deep valleys, creating dramatic landscapes like U-shaped valleys and fjords. In contrast, continental glaciers, which cover vast areas like Greenland and Antarctica, reshape the land through a more uniform, extensive flattening, leading to features such as drumlins and glacial till plains. The scale and movement patterns of these glaciers result in distinct landforms and ecological impacts on their respective environments.
