A"dip needle" is a small magnet mounted on a horizontal axis so that it can swivel up or down (like a compass turned on its side). where on earth will a dip needle point most nearly vertically? where on earth will it point most nearly horizontally?

Explained

Explanation:

The dip needle will point most nearly vertically near the earth's magnetic poles,(earths magnetic poles are opposite of earth's actual poles) where the field points towards or away from the poles. It will point most nearly horizontally near the equator.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
