Why is Greenland cold enough to have an ice sheet, while North America is not?

North America is hotter than green land

Explanation:

because green land is in the south and north America is in the north and the south is cold and the north is hot

The majority of Greenland is much further away from the equator than North America, causing the temperatures to drop to the point where an ice sheet is created. The further away a country is away from the equator, the less direct rays from the sun hit it. Countries closer to the equator are hit by more direct rays.

Hope this helps! :)

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
