Earth’s Layers

Earth’s Layer The Earth is like a giant layer cake made up of many different layers and different fillings. Except the Earth fillings are not made up of good tasting frosting and cake but more rocks and metal. The Earth is divided into four different...

The earthquakes all around the world

An earthquake is when the ground starts shaking caused by a slip on a fault. Stresses in the earth’s outer layer push the sides of the fault together. Stress builds up and the rocks suddenly slip releasing a ton of energy in waves that travel...

The versatile nature of carbon

Carbon in its various forms has been known since ancient times in the form of soot, charcoal, graphite and diamonds. Its name is derived from a Latin word “carbo” which means “charcoal”. Ancient cultures did not realize, of course, that these substances were different forms...

Earth’s magnetic field

Earth’s magnetic field, albeit generated approximately 2,000 miles below the surface, protects the planet’s atmosphere from space radiation and solar wind. It is essential, then, for life. The strength of the magnetic field, though, is rapidly decreasing; in the past 300 years alone, its strength...

The Parts of an Earthquake

Parts of an Earthquake?-Earthquakes happen when two pieces of Earth all of the sudden slip past each other. The surfaces that slip past each other are called fault line or fault plane. An earthquake starts in the hypocenter, which is located beneath Earth’s surface. Right...

The characteristics of a magnetic field

Magnetism produces lines of force known as flux. These can be detected by compass needle which shows the direction you are travelling as the earth’s magnetic north pole attracts the north ends of other magnets. The magnetic lines of force start from the north pole...
