A landslide or mudslide can occur when heavy rain saturates the ground on a hillside, causing the soil to become unstable and slide downhill.
The movement of rock and soil down a hillside or mountain is called mass wasting or mass movement. This can occur due to the force of gravity acting on loose material, steep slopes, heavy rainfall, earthquakes, or human activities that disturb the natural stability of the land.
The water content of the soil on a hillside is most likely to trigger a mass movement during heavy rainfall or after a period of prolonged precipitation. This increased water saturation can weaken the soil structure, causing it to become unstable and potentially lead to a landslide or mudslide. Factors such as steepness of the slope, soil composition, and vegetation cover also play a role in determining when a mass movement might occur.
A soil-covered hillside with sparse vegetation is more susceptible to severe soil erosion because vegetation helps to anchor the soil in place with its roots and provide a protective cover against the impact of raindrops. Without this protection, rainfall can easily dislodge and transport soil particles downhill, causing erosion to occur at a faster rate.

Terraces can be used to convert sloping ground on a hillside or mountain side into a series of flat plateaus of gradually changing elevation. This tremendously cuts down on the soil erosion which would otherwise occur if you were to do farming on sloping ground.

This process is known as a spring. Springs occur where the water table intersects the ground surface, allowing groundwater to flow or bubble out through cracks or openings in the rock. Springs are important sources of freshwater and can vary in size and flow rate depending on local geology and hydrological conditions.
The different types of water springs are artesian springs, natural springs, geyser springs, and seep springs. Artesian springs are pressurized and occur when groundwater flows to the surface due to geological formations. Natural springs are formed when groundwater rises to the surface through permeable rock layers. Geyser springs are characterized by intermittent eruptions of hot water and steam. Seep springs are small, slow-flowing springs that emerge from the ground due to underground water sources.
