THE EARTH

The distance between the sun and the earth’s position as the third planet. It seems to be a giant blue marble when viewed from space. The axis of the earth rotates continuously. The axis of the earth is a line that is imagined to run from the north pole all the way down to the south pole. The angle that the Earth’s axis makes with the plane of the orbit is approximately 6612 degrees.

The Earth rotates in both directions. It does so while moving in an orbit around the sun, and it completes one rotation on its axis every 24 hours. This revolution is responsible for day and night, and the tilt of the earth on its axis is what causes the four distinct seasons. The path that Earth takes around the sun is elliptical, giving it an oval appearance.

The make up of the earth
There are several different strata in the earth’s crust. The crust is the name given to the topmost layer, which is composed of soil and brittle rock.

It is estimated that water covers around 70 percent of the surface of the world (oceans and seas). The mantle is the name of the layer that lies under the crust. This is made up of solid rock that has been partially melted.

The lithosphere is comprised of the crust as well as the upper section of the mantle that is solid. The asthenosphere is the name given to the bottom portion of the mantle, which is composed of rock that has been partially melted.

The core of the earth is located directly underneath the earth’s mantle and in the exact center of the planet. Iron makes up the majority of the core’s constituents. The solid outer core surrounds a liquid metal core. It is generally accepted that the molten metal present at the center of the earth is responsible for producing the earth’s magnetic field.

When it comes to pinpointing specific locations on Earth, lines of latitude and longitude prove to be quite helpful tools.

Latitude lines are fictitious lines that are imagined to be drawn around the world and are positioned so that they are parallel to the equator. The lines of longitude are fictitious lines that run perpendicular to the equator from pole to pole, starting at the North Pole and ending at the South Pole.
