Earth moves in two ways. It moves in orbit around the sun and it turns on its axis once every 24 hours. This rotation produces day and night and the titling on its axis gives us different seasons. Earth's rotation around the sun is oval in shape or elliptical.
Inside the earth
The earth is made up of different layers. The top layer is made up of soil and hard rock and is known as the crust.
Around 70% of the earth's crust is covered with water (oceans and seas). Below the crust is another layer called the mantle. This is made up of solid and partly melted rock.
The crust and the solid upper part of the mantle are called the Lithosphere. The lower portion of the mantle made up of partly melted rock is called the asthenosphere.
Below the earth's mantle and at the center of the planet is the core. The core is mostly composed of iron. The outer core is liquid metal. It is believed that earth's magnetic field is generated by the liquid metal found in the earth's core.
Lines of latitude and longitude are very useful for locating exact areas on the earth.
Lines of latitude are imaginary lines drawn around the earth that are parallel to the equator. Lines of longitude are imaginary lines running from the North Pole to the South Pole and at right angle to the equator.
