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.Know More
Tornadoes, hurricanes, volcanoes, tsunamis, and earthquakes are all examples of destructive forces. The Grand Canyon is a result of destructive force. It was carved by water, which is one of the three agents of erosion. Erosion is a natural destructive process in which rock, soil or sediment is displaced or worn away. The other two agents of erosion are wind and ice. Ice erodes in the form of glaciers, forming valleys, and moraines. The third agent of erosion, wind, carries grains of sand that wear away at rocks.
Destructive forces can also be constructive. For example, as wind carries sand away from one region, it moves it to another and constructs sand dunes. Likewise, water forms deltas by depositing sediment at the mouth of a body of water.
The movement of tectonic plates can be constructive, forming volcanoes as plates converge or diverge. Iceland was formed, for example, by moving plates. Volcanoes are a destructive force because their eruptions destroy trees and other landmarks, but the magma they produce can be constructive as it dries on land to form mountains. Tectonic plate movement can cause earthquakes, which is another example of a destructive force that breaks apart land. Often, earthquakes and volcanic eruptions occur simultaneously as the result of plate tectonics.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 >
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 >
The definition of a natural resource is something that is found in nature that is useful to humans. All natural resources are finite, meaning once they are used, they cannot be replaced. Many valuable natural resources, such as gold and oil, have been nearly depleted, while others are still abundant.Full Answer >
Earth's atmosphere, which is around 300 miles thick, is mainly made of nitrogen and oxygen, although there are many other trace substances in its composition. Trace substances make up only 1 percent of the bulk of the atmosphere while nitrogen (78 percent), oxygen (21 percent) and argon (1 percent) make up the rest.Full Answer >
