The Earth-Our World Test 1

• Globes show us primarily oceans and continents.
• A globe is a circular device for locating places.
• The globe circles around a stand instead of using a map.
• The globe displays the outlines of each continent, usually in different colours.

The Arctic Ocean is the smallest of the world's five ocean basins. The Arctic Ocean is about 1.5 times as big as the United States.

• The sun is a big ball of gas and plasma. Most of the gas 91 percent is hydrogen.
• It is converted into energy in the sun's core.
• The energy moves outward through the interior layers, into the sun's atmosphere, and is released into the solar system as heat and light.
• So, It can be said that Sun is a star and has its own heal and light.

In order of distance from the sun they are; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

An equator is an imaginary line around the middle of a planet or other celestial body.

An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere.

The Earth is massive enough that the pull of gravity maintains its roughly spherical shape.

Earth is called the "Blue Planet" due to the abundant water on its surface. This is because liquid water covers most of the surface of the planet.

A geographical pole or geographic pole is either of the two points on Earth where its axis of rotation intersects its surface.

Globe, sphere or ball that bears a map of the Earth on its surface and is mounted on an axle that permits rotation.

The Pacific Ocean is the largest and deepest of the world ocean basins.

Covering approximately 63 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins.
