Cold area where the sun's rays strike at a very low angle?
The Polar regions.
What are two ways Polar Regions and Deserts alike?
Two ways polar regions and deserts are alike is that they both have very little precipitation, and short, delicate food chains due to low species diversity.
Why do marine organisms living in polar regions have a very high proportion of cholesterol in their membrane?
Marine organisms living in polar regions have a very high proportion of cholesterol in membranes to keep the membranes more fluid and keep the molecules moving faster because in cold temperature, molecules move slower.
What layer of the atmosphere does not exit above the polar regions?
Layer of atmosphere which is not present over poles is Ozone. It is due to very cold temperature.
Why do ice cores taken from polar regions contain much older information about earths climate than icecores taken from mountaintops?
Because the snow is very compressed in the polar regions
Very long days or nights occur at the?

Explain how the salinity of water in polar regions very seasonally?
The salinity of water in polar regions varies seasonally because of the melting of sea ice during warmer months.
Cold area where the sun's rays strike at a very low angle?
The Polar regions.
Why do ice cores taken from polar regions contain much older information about Earth's climate than ice cores taken from mountaintops?
Because the snow is very compressed in the polar regions
Why are reptiles rarely found in the polar regions?
Because they are cold-blooded. Most reptile species need the sun to keep them warm, and temperatures in the Polar regions are very cold and dry. Hope this helped, Umi.
Why are fur bearing animals mostly found in cold polar regions?
as the polar regions are very cold , the fur bearing animals like polar bear, squirrel, snow fox, polar wolves, reindeer etc are found the thick wool present on the body of these animals protect them from severe cold.
Why plants in polar regions have very short growing season?
because in th polar regions you only have sun for around six months of the year the other six months or so is pitch black the whole time
Why plants in the polar region have very short growing season?
Polar regions have short summers and long winters. It's to do with the amount of sunshine that those regions get. The sun's rays strike the ground at a different angle in the polar regions so they are not as warm.
How is polar bear able to survive in the polar region?
Polar bears body temperature is alsways high. Their skin also very thick and wool like maintain their bodies warm. Therefore they can survive in polar regions.
