What is the difference between sea ice and ice of terrestrial origin?
The most basic difference is that sea ice forms from salty ocean water, whereas icebergs, glaciers, and lake ice form from fresh water or snow. Glaciers are considered land ice, and icebergs are chunks of ice that break off of glaciers and fall into the ocean.
What is the difference between sea ice and glacier ice?
What is the difference between sea ice and glaciers? Sea ice forms and melts strictly in the ocean whereas glaciers are formed on land. When glaciers melt, because that water is stored on land, the runoff significantly increases the amount of water in the ocean, contributing to global sea level rise.
What is the difference between land ice and glacier?
Basically, glaciers originate on land, and ice floes form in open water and are a form of sea ice. Glaciers that extend in continuous sheets and cover a large landmass, such as Antarctica or Greenland, are called ice sheets. If they are similar but smaller, they are termed ice caps.
Is sea ice stronger than freshwater ice?
Freshwater Ice. The lower the temperature, the stronger the ice. From the table it can be seen that the sea ice has to be between 56\% and 65\% thicker than the lake ice to support the same load.
What is the difference between sea ice and land ice in Antarctica and the Arctic?
The Arctic is an ocean, covered by a thin layer of perennial sea ice and surrounded by land. (“Perennial” refers to the oldest and thickest sea ice.) Antarctica, on the other hand, is a continent, covered by a very thick ice cap and surrounded by a rim of sea ice and the Southern Ocean.
What is land ice?
Land ice includes mountain glaciers and ice sheets, covering Greenland and Antarctica. These giant blocks of ice are melting and the water is flowing rapidly into the oceans. Think of it like adding water to an already full glass – it soon overflows. But melting sea ice behaves differently.
What is the difference between glacier and snow?
Glaciers are comprised of snow and ice, compressed into large masses. Glaciers form as snow remains in a single place long enough to transform into ice. Glaciers advance and recede, meaning they flow, like a very slow moving river.
What are examples of land ice?
Land ice includes mountain glaciers and ice sheets, covering Greenland and Antarctica. These giant blocks of ice are melting and the water is flowing rapidly into the oceans.
What is glacier water?
Glacier water is old water, sometimes formed more than seventeen thousand years ago. Typically, it has an extremely low mineral content and is similar in taste and other qualities to rainwater.
