Glaciers

Icebergs are formed when chunks of ice break off from glaciers or ice shelves. They float in water because ice is less dense than liquid water. This is due to the fact that ice takes up more space than the same amount of liquid water, allowing icebergs to displace enough water to stay afloat.

Bedrock that is scratched by boulders held in the bottom of glaciers is said to be "polished and striated." This process occurs through glacial abrasion, where the boulders act like giant sandpaper, scraping and smoothing the bedrock as the glacier moves over it.

1. Glaciers in the Northeast region sculpted the landscape by carving out valleys and fjords as they moved and melted, creating unique geological features like the Finger Lakes in New York and the White Mountains in New Hampshire.
2. The weight and movement of glaciers reshaped the region's topography, depositing sediment and creating moraines, eskers, and drumlins that influence local soil composition and drainage patterns.

Glacier movement is primarily caused by the force of gravity pulling the ice downhill. As a glacier accumulates snow and ice, the weight of the ice causes it to slowly flow under its own mass. Additionally, meltwater at the base of the glacier can help reduce friction with the underlying bedrock, facilitating movement.

Glaciers in Europe sculpted the landscape by eroding valleys, carving out fjords, and depositing large amounts of sediment, shaping the present-day topography. They also helped shape the Great Lakes and other important landforms in the region.

The Saxons left behind medical equipment such as bone instruments, bronze scalpels, and cautery tools. These ancient tools reflect their understanding of basic surgical procedures and medical practices during that time period.

Glacial grooves in Antarctica can be found on exposed rock surfaces, typically on nunataks or other high points where glaciers have flowed over the rock and carved out grooves with their abrasive action.

Leaving a legacy allows you to be remembered for your contributions and impact on others. It can inspire future generations and create a lasting positive influence on the world. It is a way to leave a mark on the world that goes beyond your lifetime.

No, glaciers are more dense than fresh snow. Over time, layers of snow accumulate and compress under their own weight to form dense glacial ice. This densification process reduces air pockets within the snow, resulting in the formation of denser ice in glaciers.

Glaciers shaped the Canadian landscape by sculpting valleys and creating lakes through erosion and deposition of sediment. They also left behind large deposits of till and moraines, contributing to the diverse topography of Canada. Melting glaciers have continued to impact the landscape by forming iconic features such as the Great Lakes and Niagara Falls.

One thing they did as they moved was scrape the land until they stopped and left deposits about two thirds down the state. Northern and central Illinois are rather flat, but southern Illinois has beautiful limestone cliffs, gorges and lakes. The same thing occurred in Indiana at the same time.

Glaciers are not currently present in Britain. The last glaciers in the UK melted at the end of the last Ice Age, around 11,000 years ago. However, there are still some remnants of glaciation in the form of glacial features such as corries, cirques, and U-shaped valleys in the Scottish Highlands and Snowdonia in Wales.

Yes, the Inuits have left behind various artifacts such as tools, weapons, clothing, and carvings. These artifacts provide insights into their way of life, traditions, and skills in adapting to the Arctic environment. Many of these artifacts are well-preserved due to the cold temperatures and have been valuable sources of information for archaeologists and anthropologists.

The Aleuts primarily left behind artifacts of their material culture, such as tools, weapons, and household items. These artifacts offer valuable insights into their way of life, traditions, and interactions with the environment. Additionally, they also left behind oral histories and folklore that provide a deeper understanding of their beliefs and practices.

Generally, you can always find ice at higher altitudes, even in temperate climates.

There is always ice on every continent on earth. Notably, 98% of the Antarctic continent is covered with an ice sheet, as is Greenland, with about 80% of its surface covered with an ice sheet.

Different communities developed during primary succession at Glacier Bay starting with pioneer species like lichens and mosses, which helped break down rock and soil. This allowed for the establishment of grasses and herbs, followed by shrubs and eventually trees. Each stage of succession created conditions for the next stage to establish, leading to a diverse ecosystem.

There are no glaciers on Fiji. It's too warm for a start.

Glaciers are not typically considered part of the Arctic tundra biome. The Arctic tundra is defined by cold temperatures, a short growing season, and a layer of permanently frozen subsoil known as permafrost. Glaciers, on the other hand, are massive sheets of ice that form from the accumulation and compaction of snow over long periods of time in mountainous regions.

here in dc theres some snow but not as much as nyc area or Boston area.

it really sucks that here its rain but then i hear theres been a foot of snow in nyc and Boston. But generally 10-20inches a year

Glaciers are large bodies of ice that move slowly over the land. In Canada, glaciers have carved out landscapes, forming valleys, lakes, and mountains. They have also deposited sediments, shaping the country's terrain and contributing to its rich biodiversity.

Valleys are formed by glaciers through a process called glacial erosion. As glaciers move, they pick up rocks and debris, which act as tools to scrape and carve the underlying bedrock. Over time, this erosion deepens and widens the valley, creating the distinctive U-shape commonly associated with glacial valleys.

Leaving belongings behind during a fire at the workplace is important because evacuating quickly is critical for personal safety. Trying to collect belongings can waste valuable time and put individuals at risk of harm or injury. Material belongings can be replaced, but the priority should always be on getting to safety.

Glaciers are found on every continent except Australia. Some of the largest concentrations of glaciers are in Antarctica, Greenland, the Arctic, and high mountain ranges like the Alps, Andes, and the Himalayas.

Yes, glaciers can create both rivers and lakes. When glaciers melt, they release water that can flow into rivers or accumulate in depressions to form lakes. This often occurs as part of the glacial melting process in areas where glaciers are present.

Yes, an ice sheet is a type of glacier. It is a large, thick mass of ice that covers a vast area of land and can flow in various directions under its own weight. Ice sheets are typically found in polar regions like Antarctica and Greenland.
