- Destructive forces, such as erosion, weathering, and earthquakes, can significantly alter the Earth's surface. Erosion wears down landforms over time, while weathering breaks down rocks and minerals. Earthquakes, on the other hand, can cause sudden and dramatic changes to the landscape, reshaping the Earth's surface in a matter of seconds.

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...

- Landslide. The movement of sediments down the slope under the influence of gravity leads to a landslide. The process of weathering causes the large mountains and rocks to wear and tear.
- Mudslide. When a huge amount of water flows onto a steep slope, it tends to drive away a part of the mud, soil, and other sediments that come into its pathway.
- Barrier Islands. In seas, the waves of ocean current drive away a part of the soil, sand, or sediment present on the shore. This flattens the river bed or the ocean shore.
- Bending of River. Water flowing into the rivers and their tributaries take the sediment particles away with the flow. Usually, rivers are observed to have a comparatively steeper cliff on the outer side than the inner side.
Land forms are the result of a combination of constructive and destructive forces. Constructive forces include crustal deformation, volcanic eruption, and deposition of sediment, while destructive forces include weathering and erosion.
Aug 15, 2018 · Despite their reputation as destructive forces, volcanoes actually were critical to the development of life on Earth. Without volcanoes, most of Earth's water would still be trapped in the crust and mantle.
Feb 19, 2022 · Great forces from within causes the surface to heave and buckle, sometimes with disastrous consequences to humans. Energy received from the sun drives processes like those that create majestic sand dunes and carve magnificent stream valleys.
Destructive forces modify or even destroy landforms. Earth’s surface is constantly changing. Change can happen rapidly, as when a volcano blows itself apart, or slowly, as in the grain by grain erosion of a stream into a canyon.
