Which Earth material has the highest albedo?
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.
Would snow have a low or high albedo value?
Snow would have a high albedo value. Albedo is a measure of how well a surface reflects solar energy. Snow reflects a high percentage of sunlight, which is why it appears bright, giving it a high albedo value.
Which surface would have the highest albedo?
A surface covered in freshly fallen snow would have the highest albedo, reflecting the most sunlight back into space.
How does water affect the melting temperature of a mineral?
Water can lower the melting temperature of a mineral by acting as a flux or catalyzing agent, allowing atoms to move more freely and reducing the energy required for melting. This can lead to the formation of new minerals or phases at lower temperatures than would occur without water present.
Which would most likely have caused the giant ice caps that existed in Paleozic era to melt?
Changes in the Earth's orbit and axis tilt, increased volcanic activity releasing greenhouse gases, and decreased albedo due to the removal of vegetation cover could have contributed to the melting of the giant ice caps that existed in the Paleozoic era.
How does a low albedo affect the earth?
A low albedo means that a surface absorbs more sunlight and heat, leading to warming. This can contribute to climate change by increasing temperatures and melting ice caps, which in turn can lead to rising sea levels and changes in ecosystems.
Which cause more light reflection albedo 2 or albedo 3?
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.
How does albedo relate to the study of climate change?
Scientists use the term albedo to define the percentage of solar energy reflected back by a surface. Understanding local, regional, and global albedo effects is critical to predicting global climate change. The following are some of the factors that influence the earth's albedo: Clouds, Surface, Oceans and Forests
A popsicle melting is physical or chemical change?
Melting is a physical change.
Melting sugar cube is what change because the substance still is sugar?
Melting a sugar cube is a physical change because the substance remains sugar, just in a different form (solid to liquid). The chemical composition of sugar does not change during the melting process.
Would A higher albedo result in an overall cooler climate?
Yes, a higher albedo would result in an overall cooler climate. A higher albedo means that more sunlight is reflected back into space instead of being absorbed by the Earth's surface, which would lead to lower temperatures.
What kind of change occures when ice become liquid water?
physical change because it is melting and it would be the same mass as it waas as a chunk of ice
Which has a higher albedo sea ice or soil?
naturally sea ice would have the advantage of having a greater albedo
Mars has an albedo magnitude of?
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.
What effect would increasing the quantity of paradichlorobenzene have on the melting point temperature?
The melting point of the substance should not change as all substances have specific melting, boiling, condensation, and freezing points. It would, however, require more energy (in this case, heat) to melt the increased quantity of paradichlorobenzene in the same amount of time.
Which process would change a metamorphric rock to an igneous rck?
Melting.
Is iron melting a physical change?
Melting iron is a strictly physical change (change of state). The molten and solid iron would be identical by any chemical test or reaction.
