What is the importance of albedo?
The albedo effect reflects the sun's radiation helping to slow the effects of global warming (like sea ice, white ice caps and glaciers). If (or when) these melt, then the reflection will stop and the warming will speed up!
Does ice reflect sunlight like a mirror?
Sea ice has an albedo of between 0.5 and 0.7. This means that it reflects between 50 and 70% of the sun's radiation (that lands on the ice).Ice with snow on it has a higher albedo, between 70 and 90%.Of the 100% of the sun's radiation that reaches the earth, 4% is reflected by the earth's surface, with about 2% reflected by ice.
Why are warming temperatures causing a vicious cycle that leads to more warming?
Warming temperatures are melting sea ice in the Arctic. There is an albedo effect at the moment, which means that a lot of the sun's heat is reflected off the ice and back into space. If the ice melts then that reflective matter disappears and the darker sea below will absorb more heat and warm more quickly.
Is the acceleration of global warming due to changes in the reflection and absorption of sunlight?
The albedo effect, characterised by changes in the reflection and absorption of sunlight, does play a small role in global warming, but requires global warming to be underway before it can play that part. As the world warms, ice caps and sea ice melt. Ice reflects much of the sun's energy back into space, but when the ice disappears the open sea and land absorb much of the sun's energy, becoming warmer. This accelerates global warming.
How is sea ice different to freshwater ice?
Sea ice contains frozen minerals, such as salt, that is not frozen into freshwater ice.

What is the difference between albedo in rural and urban settings?
"Albedo" is the refectivity of something. Snow and ice have a high albedo since they are white. Pavement has a low albedo since it is darker. Albedo is important because it reflects sunlight back into outer space. As more and more glaciers, snowpack and pack-ice at sea melt away, less sunlight is relected into space and more light is absorbed as heat by the land and sea. This heat accelerates global climate change.

Is there soil in the sea?
yes i think that there is soil in the sea
How is the melting of Arctic sea ice contributing to climate change?
It does? Yes, it does. Before it melts, the ice reflects the sun's rays back out into space. This is called the albedo effect. After it melts, the sun's rays land on the black waters of the Arctic Ocean, which doesn't reflect the rays, but absorbs them, and the water gets hotter. This is how the melting ice causes more warming.
Why does higher temperatures reduce the annual volume of sea ice and expose more open water in the Arctic Ocean?
Increasing the temperature more ice is melted.

What are some major earth surfaces that reflect the suns energy?
Any white or light colored surfaces reflect the sun's energy. The main ones are the Arctic sea ice, the Greenland ice cap, the whole of Antarctica and glaciers and snow cover all round the world. This reflective effect is called the albedo effect.
What soil does Antarctica have?
The Antarctic continent is classified as a desert because of its low humidity -- about five percent. The continent is covered -- 98% -- by an ice sheet, and the bedrock under the ice sheet is composed of the rocks and rock formations found on every other continent. Since only the beaches are not covered, the 'soil' on the continent is sea-washed stone rubble, like you would find on any beach.
When the glaciers that covered large parts of Earth melted after the last ice age did the the sea levels become higher?
Yes
What type of soil do turtles like to be in?
sandy soil (this the only soil found in the sea or ocean and turtles live in the sea or ocean
