Glaciers
Glaciers are large, dynamic bodies of ice that form over long periods of time when snow accumulation exceeds ice ablation. They are among the most significant forces shaping Earth's landscape over long time scales. Glaciers are currently found at Earth's poles and in mid-latitude and equatorial mountains.

How does the legend of the paiute people agree with theory of an ice free passage between glaciers?
because it melted for the ice-age
Where are some place you can see real glacier?
Some places where you can see real glaciers include Alaska, Patagonia in South America, Iceland, Norway, and New Zealand. These locations offer stunning glacial landscapes and opportunities for glacier trekking or ice climbing.

When the base of a glacier melts and refreezes?
When the base of a glacier melts and refreezes, it creates a layer of water that can facilitate movement, allowing the glacier to slide over the bedrock more easily. This process can lead to the formation of features like subglacial lakes and can affect the glacier's overall dynamics and stability. Additionally, the melting and refreezing can alter the glacier's internal structure, potentially influencing its flow patterns and contributing to its eventual retreat.
What is it called when glaciers move down a mountain?
When glaciers move down a mountain, it is referred to as "glacial flow" or "glacial movement." This process occurs due to the force of gravity acting on the ice, causing it to slide and deform as it flows. Additionally, the movement can be influenced by factors such as temperature, the slope of the terrain, and the presence of meltwater at the glacier's base.
Are scientists studying ways to tow valley glaciers?
Yes, scientists are studying various methods to tow valley glaciers as a potential strategy to mitigate the effects of climate change and sea-level rise. One proposed method involves using large ships to tow icebergs or glaciers to colder regions where they can remain frozen. However, this approach is still in the experimental stage and faces significant technical, logistical, and environmental challenges that need to be addressed before implementation.
What percentage of glaciers cover Earth today?
Today, glaciers cover approximately 10% of the Earth's land surface. This includes ice sheets in Antarctica and Greenland, as well as smaller glaciers found in various mountain ranges around the world. Overall, the total volume of glacial ice is diminishing due to climate change, impacting sea levels and ecosystems.
The Slessor Glacier is located in East Antarctica, specifically on the coast of the Amery Ice Shelf. It flows into the shelf from the East Antarctic Ice Sheet and is situated near the Prince Charles Mountains. The glacier is notable for its size and the role it plays in the dynamics of the Antarctic ice system.
What part of a glacier is slowest?
The slowest part of a glacier is typically the base, where it is in contact with the ground. Here, the glacier experiences friction with the underlying bedrock or sediment, which slows down its movement. Additionally, the glacier's terminus, or snout, can also be slower as it approaches a stable position before melting or calving.
