The Denmark Strait is a 300km wide stretch of water that separates Iceland from Greenland. This thin strait, although tiny in the context of the Atlantic Ocean, just so happens to be one of the most important ocean channels in the world.

Is Antarctica a desert and why?
Despite its thick ice, Antarctica is classified as a desert because so little moisture falls from the sky. The inner regions of the continent receive an average of 2 inches (50 millimeters) of precipitation—primarily in the form of snow—each year. More rain falls in the Sahara desert.

Why do only males have adam apples?
When the larynx grows larger during puberty, it sticks out at the front of the throat. This is what's called an Adam's apple. Everyone's larynx grows during puberty, but a girl's larynx doesn't grow as much as a boy's does. That's why boys have Adam's apples.

Do whales drink salt water?
DOLPHINS and other sea-dwelling mammals can obtain water from their food and by producing it internally from the metabolic breakdown of food. Although some marine mammals are known to drink seawater at least on occasion, it is not well established that they routinely do so.
