Melting ice caps increases the amount of light absorbed from the sun since the oceans absorb instead of reflect light, thus albedo, the ability to reflect light from the surface, is diminished.
Probably snow, if your Earth includes the totality of items found on the planet. Some clouds would have an albedo almost as high - but only in parts. If you wish to limit your answer to earth solids, then perhaps milky quartz, and marble would have a high albedo.
continental ice sheets and snow felts
A change in temperature of the core would probably have to be rather large to be noticeable, however it would affect plate tectonics. Lowering the temperature of the core would slow down activity and raising it would increase.
Snow, particularly fresh snow, has some of the highest albedos of anything on Earth's surface.
The freezing point and melting point of a substance are the same, so the melting point would also be 52 degrees celsius.
A lower albedo would mean that the Earth would absorb more solar energy and warm up more.
Albedo is a measure of reflectivity; it is a measure of the percentage of light reflected from a surface. A perfect mirror would have an albedo of 1, while white snow has an albedo of about 0.9. Charcoal has an albedo of about 0.04.An albedo higher than 1 is impossible.
Melting! A physical change would be to change something from Solid <--> Liquid <--> Gas
Melting is a physical change.
Melting is a physical change; but when the temperature is sufficiently high sugar is thermally decomposed - and this is a chemical change.
The albedo of Mars is .15; you can see the albedo of all of the planets and moons in the solar system at the Nine Planets web site, linked below. "Albedo" is a measure of how reflective a body is. The higher the number, the more reflective the surface. So a high albedo says that a planet or asteroid reflects most of the light that hits it, while a low albedo indicates that most of the light is absorbed. Albedo can make calculations about climate change difficult. A planet with a high albedo reflects much of the Sun's light and heat, causing it not to heat up as much. A low albedo means that all of the solar radiation is absorbed and turned into heat. A warmer world will have less snow and ice cover, and thus a lower albedo, resulting in higher temperatures. On the other hand, a warmer world might have more clouds, which would increase Earth's albedo, reflect more sunlight, and reduce the heating effect. However, clouds also act to trap heat, sort of like a blanket. Whether the albedo effect would offset the "blanket" effect of clouds would depend on the type and height of the clouds and where they are located. Cloud effects are among the most important sources of uncertainty in modeling future climate change.
Hydrogen bonding
physical change because it is melting and it would be the same mass as it waas as a chunk of ice
A higher albedo would mean that more energy would be returned to space. This would mean a cooler climate.
No, that would only be a physical change.
naturally sea ice would have the advantage of having a greater albedo
Albedo is the fraction of sunlight that hits a planet that is reflected back out into space. A bright white planet that's full of ice would have a high albedo.
