When the Earth formed, the lighter elements floated to the surface where they cooled to form a crust. Although the first rocks were formed over 3,500 years ago, they have not stayed the same. They have been changed from forces on the inside and the outside of the Earth. The coastlines on each side of the Atlantic appear to have a jigsaw fit.

The ocean currents are different in summer and winter. The wind direction can change which ocean current will be influencing the weather in a country. A cold ocean current can make the weather cold, while a warm ocean current can make the weather warm.

For centuries, most people assumed that the cold, black depths of the ocean supported little or no life. Scientists have since discovered a great variety of living things in the deep sea.

Spring tides are tides with unusually high ranges twice per month when the Sun, Earth, and Moon are in line. They can be especially high in the spring and autumn.

The Pacific Ocean, the largest and deepest of the world’s four oceans, covers more than a third of the Earth’s surface and contains more than half of its free water.

In the mid-1900s, the Royal Greenwich Observatory was moved from Greenwich to Herstmonceux Castle in Sussex to avoid interference from London lights.

But under the time zone system, each of these places is not on its own local time. The local time at the meridian (line) of longitude that runs through the middle of the zone is used by all places within the zone. Thus, time throughout the zone is the same.

Geographers divide the Earth into hemispheres by using the equator as a boundary line. All areas north of the equator make up the Northern Hemisphere. All areas to the south make up the Southern Hemisphere.

There is no regular change in the sky that lasts seven days, to represent the week. The seven-day week came from the Jewish custom of observing the Sabbath (day of rest) every seventh day. The division of a day into 24 hours, an hour into 60 minutes, and a minute into 60 seconds probably came from the ancient Babylonians.
