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 the ice in the Antarctica does not melt away into the sea when sunlight shines on it?
The reason the ice in the Antarctica does not melt away when sunlight shines upon it is because the whiteness of the ice reflects most of the light back into space. But as a result of global warming, much more ice are being melted now than before. And thus without the ice, more sea will appear. And with the sea, there were not as much ice to reflect the sunlight back into space, therefore more of the sunlight and its heat were absorbed by earth, and thus more and more ice will melt.
What is the glare around the sun made of?
The glare around the sun, often referred to as a halo, is caused by sunlight interacting with ice crystals in the atmosphere. These ice crystals refract and reflect the sunlight, creating a ring of light around the sun.
Will colour affect how fast ice will melt?
The color of ice will affect how fast it melts due to its impact on the absorption of sunlight. Darker colors absorb more sunlight and heat, causing ice to melt faster compared to lighter colors that reflect more sunlight. This phenomenon is known as the albedo effect, where darker colors have lower albedo and absorb more heat energy. Therefore, the color of ice can influence its melting rate.
Much of the sun radiation is reflected back into space by the earths what?
Much of the sun's radiation is reflected back into space by the Earth's atmosphere, clouds, and surface. The atmosphere scatters and absorbs some solar energy, while clouds can reflect sunlight back into space. Additionally, surfaces like ice, snow, and water can also reflect sunlight, a phenomenon known as albedo. Together, these elements play a crucial role in regulating the Earth's temperature and climate.
What is the texture of clouds?
Clouds have a soft, fluffy texture that can appear smooth or billowy depending on their type and altitude. They are composed of tiny water droplets or ice crystals that reflect and scatter sunlight, giving them their distinct appearance.
Ice caps more light than deserts because they have a higher albedo?

What causes clouds to reflect sunlight back to space?
Clouds reflect sunlight back to space due to their high albedo, or reflectivity. This happens because clouds are made up of tiny water droplets or ice crystals that scatter incoming sunlight. The more dense and widespread the clouds, the more sunlight they can reflect back into space.
What is the high albedo definition and how does it impact the Earth's climate?
High albedo refers to the ability of a surface to reflect sunlight. Surfaces with high albedo, like ice and snow, reflect more sunlight back into space, which can cool the Earth's climate by reducing the amount of heat absorbed. This can have a significant impact on global temperatures and climate patterns.
Will the temperature of the sea rise due to icecap meltdown?
The temperature of the arctic ocean is expected to rise if the ice cap disappears because the water will absorb sunlight rather that reflect it as the ice cap did. There is a question, however, of whether or not there will then be clouds over that area that will reflect sunlight or what else might happen. Interpolation from current data does not always work.
Why does Antarctica look blue?
Optically, the ice is so dense as to be able to only reflect the colour of the sky. During the sunset period, you can see other colours in the ice. Without sunlight, the ice does not appear blue.
Why the ice in the Antarctica does not melt away into the sea when sunlight shines on it?

And with the sea, there were not as much ice to reflect the sunlight back into space, therefore more of the sunlight and its heat were absorbed by earth, and thus more and more ice will melt.
What color is a cloud and why does it appear that way?
Clouds can appear white, gray, or even dark depending on the amount of sunlight they reflect and the thickness of the cloud. The color of a cloud is mainly influenced by the scattering of sunlight by water droplets or ice crystals in the cloud. When sunlight hits a cloud, the water droplets or ice crystals scatter the light in all directions, making the cloud appear white or gray. Thicker clouds can appear darker because they absorb more sunlight and reflect less light.
According to some scientists earth began as an iceball what early events led to the majority of the ice melting since snow is suppose to reflect sunlight and not absorb heat?
snow melts, right, therefore it doesn't reflect all heat. with global warming and the sun's help, most of the ice from what we call the ice age has melted.
What causes clouds to reflect a portion of sunlight back to space?
Clouds reflect sunlight back to space due to their high albedo, which is the measure of how much sunlight a surface or object reflects. The water droplets or ice crystals in clouds scatter and reflect sunlight, which reduces the amount of solar radiation that reaches the Earth's surface. This reflection plays a role in regulating the Earth's energy balance and helps cool the planet.
Why do many clouds reflect a significant amount of sunlight back to space?
Many clouds reflect a significant amount of sunlight back to space due to their high albedo, which is the measure of reflectivity. The water droplets or ice crystals in clouds scatter incoming sunlight, preventing it from reaching the Earth's surface. This reflective property helps regulate the planet's temperature by cooling the surface. Additionally, thicker and more extensive clouds tend to reflect even more sunlight, enhancing this cooling effect.
