1. Earth is the only planet in our solar system that has a large amount of liquid water. About 74% of the surface of Earth is covered by liquid or frozen water. Because of this, people sometimes call it the blue planet. Because of its water, Earth is home to millions of species of plants and animals.
2. People were afraid of traveling too far because of the very constrained circumstances in olden times. Roads were bad and became true rutted deathtraps in summer rains. The rains themselves brought another factor into play, that is combined with the types of clothing people had then.

1. At the coast the horizon facing the ocean is unobstructed, so a larger part of the sky is visible than inland, where trees, buildings, etc., block the view of the horizon. At or near the horizon the sky appears lighter blue than at the zenith, or even whitish.

6. There are two types of magnetic poles, called the north magnetic pole and south magnetic pole. North magnetic poles are those that are attracted toward the Earth's geographic north pole.
