He convinced the princely states to accede to the Indian Union by signing the “Instrument of Accession” which allowed states to join India while retaining control over internal matters.Some of Patel’s notable achievements include –

• Sardar Patel’s integration of Hyderabad was achieved through Operation Polo, a swift military action in 1948 annexing Hyderabad into India .
• Sardar Patel’s integration of Junagadh was achieved through a plebiscite in February 1948 where 99.95% voted to join India.
• Sardar Patel established the All India Services including the Indian Administrative Service (IAS), Indian Police Service (IPS) and Indian Foreign Service (IFS) to promote national unity and administrative efficiency.

Overall, Sardar Vallabhbhai Patel’s contributions to unifying India and integrating the princely states were instrumental in shaping the country’s future. His vision, leadership and dedication continue to inspire Indians to this day.

Geomorphic processes shape Earth’s surface through physical and chemical changes. The two main types are endogenic processes (internal forces like tectonics and volcanism) and exogenic processes (external forces like weathering and erosion).

Comparison and Contrast of Endogenic and Exogenic Processes –

1. Endogenic Processes are internal processes that occur inside the earth’s lithosphere specifically within the core, mantle and crustal layers whereas Exogenic Processes are external processes occurring on or above the earth’s surface shaping its landscape naturally.
2. Endogenic are driven by internal energy from radioactivity, tidal friction and earth’s primordial heat sources whereas Exogenic are driven by solar energy, atmospheric conditions and gravitational forces naturally.
3. Endogenic create geological structures like earthquakes, volcanoes and mountain ranges whereas Exogenic involve breakdown and removal of Earth’s materials through weathering, erosion and deposition forces.

Significance of weathering – 

1. Weathering is the breakdown of rocks into smaller particles due to weather and climate conditions.
2. It plays a crucial role in soil formation, supporting plant life and ecosystems through nutrient rich soil creation.
3. Weathering prepares rocks for erosion and mass wasting by weakening and breaking them down physically.
4. Weathering concentrates valuable minerals like iron, copper and manganese facilitating economic extraction and mining operations.
5. Weathering is influenced by geological, climatic and vegetative factors including temperature, rainfall and plant growth.

Endogenic processes occur inside Earth, driven by internal energy while exogenic processes happen outside, driven by external forces. Weathering, an exogenic process breaks down rocks, shaping Earth’s surface and supporting life by creating soil and nutrients.
