Tectonic and Gradational Forces

Tectonic forces and Gradational forces are two types of forces that shape the surface of the earth. Tectonic forces originate from within the earth, while Gradational forces originate from outside the earth.

Tectonic Forces

Tectonic forces are the forces that originate from within the earth. These forces are responsible for the movement of the earth's crust. The movement of the earth's crust results in the formation of mountains, valleys, and other landforms. Examples of tectonic forces include:

1. Plate Tectonics: The movement of the earth's plates is caused by the convection currents in the mantle. This movement results in the formation of mountains, rift valleys, and earthquakes.

2. Volcanic Activity: The movement of tectonic plates can also result in volcanic activity. When two plates collide, the pressure and heat can cause magma to rise to the surface, resulting in the formation of volcanoes.

Gradational Forces

Gradational forces are the forces that originate from outside the earth. These forces are responsible for the erosion and weathering of the earth's surface. Gradational forces are caused by external agents such as wind, water, and ice. Examples of Gradational forces include:

1. Erosion: The movement of water, wind, and ice can erode the surface of the earth. This erosion can result in the formation of valleys, canyons, and other landforms.

2. Weathering: Weathering is the process by which rocks are broken down into smaller pieces. This process is caused by exposure to the elements, such as rain, wind, and temperature changes.

Conclusion

In conclusion, Tectonic forces originate from within the earth and Gradational forces originate from outside the earth. Both these forces play a significant role in shaping the surface of the earth. The movement of the earth's crust and the erosion of the earth's surface are ongoing processes that continue to shape the earth's landscape.
