Answer:
A. The ice has a high albedo.
Explanation:
Albedo is a measure of ‘whiteness’ or reflectivity which is also the rate at which a surface is able to reflect a percentage of solar radiation it receives. White surfaces have a higher albedo which is why Arctic and Antarctic regions with lots of ice sheets have a high albedo. They play a big role in regulating global temperatures. The larger the ice sheet cover in the antarctic and arctic regions, the more they reflect solar radiation back to space hence keeping the temperatures on earth from rising considerably.
Prevailing winds are the planetary winds that are caused by the formation of giant convection cells over the earth. Prevailing winds blow from the hot regions of the earth, like the tropics, to the cold areas of the earth, like the temperate or polar regions, and from the cold areas back to the hotter regions.
Answer:
Hey!
Stars are formed from massive clouds of dust and gas in space CALLED NEBULAE. Gravity pulls the dust and gas together to form a PROTOSTAR...much like a baby star!
These gases come together, and as they do, the temperature begins to increase...
The finished stars are formed when the OPTIMUM TEMPERATURE is released for the chemical reactions within to start!
OUR SUN'S COLOUR IS WHITE! (Although its actually all the colours mixed together)
