what is the difference between sea ice and ice sheets?
512
The most basic difference is that sea ice forms from salty ocean water, whereas land ice (ice sheets and glaciers) form from fresh water or snow. Land ice can be labelled as ice sheets whereas sea ice can be labelled as ice shelves. They vary greatly in quantity due to seasonal changes in temperature.

Sea ice forms on the ocean's surface in chilly temperatures, starting as a thin slate of crystals that grow outward into a sheet of salty ice. Then the sea ice grows downward and thickens. ... Arctic sea ice helps to keep the polar regions cool and helps moderate the global climate.

Before going into great detail, the big difference between ice cream and frozen dessert is this. Frozen desserts are made with vegetable oil. ... Ice-cream on the other hand, is mainly made from milk and dairy fat. To do a fair comparison, I randomly picked up a box from each - a frozen dessert and an ice cream carton.

The main difference between hot and cold desert is that the hot desert is battered by a high sun whereas the cold desert has ice and the snow in the ground. Furthermore, hot deserts are closer to the equator while cold deserts are in extreme northern or southern latitudes.

So what's the difference? "Snow is made up of one or more tiny ice crystals that come together to form the intricate and unique shapes of a snowflake," says ABC weather specialist and presenter Graham Creed, "Whereas, hail is a frozen raindrop and is generally a lot bigger than a pure crystal of ice."

Scientists believe the ice sheets moderate weather by reﬂecting heat away from the Earth, and their disappearance will contribute to more extreme weather in the coming decades. Melting Arctic sea ice will also contribute to sea level rise, both as it melts into the oceans and as the warming water expands.

First, warmer temperatures cause ice on land like glaciers and ice sheets to melt, and the meltwater flows into the ocean to increase sea level. Second, warm water expands and takes up more space than colder water, increasing the volume of water in the sea. Sea level rise will hit the coasts the hardest.

An ice cap is a dome-shaped mass of glacier ice that spreads out in all directions; usually larger than an icefield but less than 50 000 km2. An ice sheet is a dome-shaped mass of glacier ice that covers surrounding terrain and is greater than 50 000 km2, such as the Greenland and Antarctic ice sheets.

An ocean is a vast body of salt water that surrounds a continent. A sea is also a body of salt water, partly or completely surrounded by land, and often connected to the ocean. ... A lake is a large body of water that is surrounded on all sides by land. Lakes are generally larger and deeper than ponds.

The primary difference between the Arctic and Antarctica is geographical. The Arctic is an ocean, covered by a thin layer of perennial sea ice and surrounded by land. ... 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.

Ice cream is churned, fatty and has air. It is supposed to have a smooth, sweet, creamy mouthfeel and melts faster than ice. Ice is hard and not sweet. ... If you can't tell the difference between ice cream and ice without looking at it, then that is some pretty poor quality ice cream or some seriously contaminated water.

An ocean is a vast body of salt water that surrounds a continent. A sea is also a body of salt water, partly or completely surrounded by land, and often connected to the ocean. Seas are generally smaller than oceans. ... A lake is a large body of water that is surrounded on all sides by land.

Ice is heavier. Solids are denser, the molecules being a lot closer. When the volume of ice compared to water has the same volume, there are more of those ice molecules in all than the water at that volume. ... Therefore, water and ice at the same volume makes ice the winner because there's more mass.

In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet. Typically, seas are partially enclosed by land. Seas are found on the margins of the ocean and are partially enclosed by land. Here, you can see that the Bering Sea is part of the Pacific Ocean.

Ice Melt Means Uneven Sea Level Rise Around the World. LONDON – Scientists say the sea level rise caused by climate change during the rest of this century will not affect all parts of the world equally, because of the ways sea, land and ice interact.
