Apr 24, 2017 · Constructive forces are those that work to build or create new formations. Destructive forces, as the name implies, destroy or tear down existing formations. Some forces qualify as both a constructive and destructive, in that they harm the existing landscape while simultaneously creating a new one.

Our Earth is ever changing. Some of these changes, like the creation of the Grand Canyon, take millions of years to happen, and some of them are catastrophic changes that occur in seconds. These changes to our Earth can be categorized as either constructive forces or destructive forces.
Some changes to the Earth take place in a matter of seconds instead of millions of years. The main quick constructive force is a volcano. A volcano that erupts violently can send lava and ash shooting out within seconds. When that lava cools, it hardens into new rock.
Destructive forces break down land. The two main forces that break down land slowly are weathering and erosion. Weathering is the breaking down of rocks due to forces such as wind and water. The pieces of rock are then moved elsewhere through the process of erosion. Weathering and erosion take millions of years to have an effect on the Earth, but t...
Quick destructive forces are forces such as earthquakes and tsunamis that can change the surface of our Earth in seconds. Tsunamis can flatten the Earth and erase hills. A tsunami will take thousands of feet of Earth and drag it back to the ocean floor. Earthquakes can cause the Earth to crack, causing sinkholes or other such phenomena. Quick destr...
A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact...
Mar 30, 2022 · In physics and other sciences, a force is a push or pull on a mass that can change the object’s motion. Force is a vector quantity, meaning it has both magnitude and direction. The symbol for force is the capitol letter F. A famous example of an equation for force is Newton’s second law: F = m*a. Here F is force, m is mass, and a is ...
Unbalanced forces mean there is a resultant force acting on the object, the effects of which will be observed. If an object’s shape is changed by being stretched or squashed, forces are acting on it. Pulling forces will stretch a material whereas pushing forces will squash or compress a material.

Deposition. Definition: is the dropping or depositing, of sediments by water, wind, or ice. Deposition builds up new land on Earth's surface, like a at the end of a river or the build up of a sand dune in the desert. Example: Deposition is dropping of sediment by wind, water, and ice. Deposition creates new land on the Earth's surface.
