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.Know More
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 about Earth Science
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 >
Some examples of destructive forces include erosion by water or wind, volcanic activity, earthquakes, the impact of glaciers and even animals' degradation of the environment. Silt and soil deposition, as well as volcanic lava flows, are examples of constructive forces.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 >
