Because it's cold up there. The atmosphere gets colder at high altitudes so the snow doesn't melt as quickly as lower altitudes. But why is it colder? Because the atmosphere is less dense than at sea level. This explains why the air is colder. But why is the GROUND colder? I presume because at sea level, there is an equilibrium (approx) maintained between the ground and the air, while higher up, the air is less dense and so the sun's radiation that arrives to the ground (mountain) is absorbed by the Earth and that ground remains cold enough to support snow. Is this correct, anyone?
Only high in the mountains and on glaciers does it remain snow covered.
The answer is mountains.
In usual text, snow-covered would probably be hyphenated - otherwise the sentence could be misinterpreted - consider the difference between the concept of "snow-covered mountains" and the sentence "snow covered mountains".

I believe that the reason they are covered with snow is because of how high the elevation they have.
The cairngorm mountains in Scotland are covered with snow in winter, spring and autumn. There is snow on the higgest peaks during summer.
At high altitudes, the air is very cold. So, in high mountains, any precipitation will fall as snow.
The Atlas Mountains in Morocco are high enough to receive snow.
There are mountains in the North Pole. At Longyearbyen, the main gateway to the Norwegian Arctic, there are snow covered mountains.
two mountains covered with snow.
If the mountains are high enough, then some snow will fall on them, but it won't stay for long.
The Swiss Alps.
The Rockies, the Smokies in winter, the Sierra Nevadas, the giant mountains of Alaska.
The Himalayan Mountains are the highest mountains in the world. They are covered in snow all year from the altitude. The higher the point, the colder it gets. So, the Himalayan Mountains are so tall that the caps are snow capped all year.
some animals that live in the high mountains are snow leopard and elk.
Nevada comes from the Spanish "covered in snow" from the Sierra Nevada Mountains.
