The correct answer is option C - Both 1 and 2.
Tectonic deformation refers to the changes that occur in the Earth's crust due to tectonic forces. These forces can lead to various types of deformation, including folding of rocks. Let's discuss each statement in more detail:
1) It is the change that occurs within the Earth's crust due to tectonic forces.
Tectonic forces are generated by the movement of tectonic plates, which make up the Earth's crust. These forces can cause the deformation of the crust, leading to changes in the shape, size, and position of rocks and landforms. Tectonic deformation can occur in various forms, including folding, faulting, and crustal uplift. Therefore, statement 1 is correct.
2) It can lead to the folding of rocks where layers of rock are bent and deformed due to compressional forces.
One of the common types of tectonic deformation is folding, which occurs when compressional forces act on the rocks. When these forces are applied, layers of rock can be bent and deformed, resulting in the formation of folds. Folds can range in size from small-scale features seen in individual rock layers to large-scale structures that extend for kilometers. These folds are often found in mountainous regions where tectonic forces have caused the compression of rocks. Therefore, statement 2 is also correct.
In conclusion, both statements are correct. Tectonic deformation refers to the changes that occur within the Earth's crust due to tectonic forces, and one of the common forms of deformation is the folding of rocks.

Recently, a study done by the researchers has found an expanding area of active tectonic deformation in the northern plains of Haryana.
- It refers to the changes and movements that occur within the Earth's crust due to tectonic forces.
- The Earth's lithosphere, which is composed of the crust and the uppermost part of the mantle, is divided into several large and small tectonic plates.
- These plates are in constant motion and interact with each other at their boundaries.
- Tectonic activity at divergent plate boundaries can create rift zones and rift valleys.
- Tectonic deformation can lead to the folding of rocks, where layers of rock are bent and deformed due to compressional forces.
Key Findings:
- Researchers suggested that tectonic activities may have played a role in the extinction of the Vedic Saraswati River that once flowed through the region.
- The Piedmont zone of Haryana is actively deforming and could become a future seismic hazard zone.
- The Piedmont zone (a transition zone between the rugged mountains and the relatively flat plains) between the Ghaggar and Yamuna River basins showed signs of active tectonic deformations.
Hence both statements are correct.
