The Earth began spinning when it was formed and doesn't stop spinning because there are no forces to stop it. The planet began spinning faster as it was being formed. Initially, the Earth's own gravity collapsed, which made it start spinning and is why it continues to spin.
The Earth rotates at a speed of around 1,070 miles per hour. If the Earth were to suddenly stop spinning, which scientists don't believe will happen in the next few billion years, the atmosphere would continue spinning and everything on the land, not attached to the bedrock, would be wiped off the planet and blown into the atmosphere.
Many scientists believe that the Earth will stop spinning but that it will do so slowly. If this occurs, every location would on the planet would be plunged into perpetual daytime or nighttime.Learn More
The Earth has a radius of 3,959 miles, a diameter of 7,926 miles and a circumference of 24,902 miles. Earth has a mass of 6.6 sextillion tons and a total surface area of 197 million square miles. It is the fifth largest planet in the solar system.Full Answer >
Astronomers theorize that over 4.5 billion years ago, Theia, an object about the size of Mars, collided with Earth to create a tilted axis. This is called "the giant impact theory." Prior to this event, the axis was straight at 180 degrees.Full Answer >
A constructive force creates or builds something on the earth. For instance, volcanoes are built up by constructive tectonic plate movement. Destructive forces like tornadoes and tsunamis tear down or wear away parts of the earth.Full Answer >
The three main examples of constructive forces are crustal deformation, volcanic eruptions and deposition of sediment. Constructive forces are the processes that build land formations. These formations include mountains and sedimentary rock layers.Full Answer >
