INDIAN GEOGRAPHY

Detailed explanation-1: -Soil forms continuously, but slowly, from the gradual breakdown of rocks through weathering. Weathering can be a physical, chemical or biological process: physical weathering-breakdown of rocks from the result of a mechanical action.

Detailed explanation-2: -Changes That Happen Slowly Slow changes of Earth’s surface include the movement of the continents, uplift, weathering, erosion, and deposition.

Detailed explanation-3: -Soil Erosion Simple Definition Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.

Detailed explanation-4: -Volcanoes, earthquakes, and tsunamis are all rapid changes and erosion and weathering are all slow changes.
