Explanation:

Landforms on Earth are the various physical features that make up the Earth's surface. These landforms are the result of several natural processes that have been shaping the Earth's surface for millions of years. One of the main forces responsible for the formation of landforms is tectonic forces.

Tectonic Forces:
Tectonic forces are the forces that result from the movement of the Earth's tectonic plates. The Earth's lithosphere is divided into several large and small plates that are constantly moving due to the convective currents in the underlying molten mantle. These forces are responsible for the creation of several landforms, including mountains, valleys, and plateaus.

Mountain Formation:
When two tectonic plates collide, they can form mountains. The collision causes the rocks at the edges of the plates to buckle, fold, and uplift, resulting in the formation of mountain ranges. The Himalayas, for example, were formed as a result of the collision between the Indian and Eurasian plates.

Valley Formation:
Tectonic forces can also create valleys. When two plates move apart or slide past each other, they can create a gap or a rift between them. This gap can be filled with water, forming a river or a lake, and create a valley. The East African Rift Valley is an example of a valley formed by tectonic forces.

Plateau Formation:
Tectonic forces can also lead to the formation of plateaus. When tectonic plates collide, the rocks can be uplifted, creating a high, flat-topped landform known as a plateau. The Deccan Plateau in India is an example of a plateau formed by tectonic forces.

Conclusion:
In conclusion, landforms on Earth are primarily formed by tectonic forces. The movement of the Earth's tectonic plates leads to the formation of mountains, valleys, and plateaus. These landforms are the result of millions of years of geological processes and continue to shape the Earth's surface. Understanding the forces that shape our landforms is crucial for geologists and scientists studying the Earth's history and its future.
