Science 5 Q4 - The Process that shape the Earth's Surface

• Gardening - It causes soil erosion when digging the soil for planting. It affects soil profile.
• Quarrying - It is the process of removing rocks from mountains to be used in construction. It can result in soil movement and sediment build-up downstream.
• Mining - It is the process of removing minerals and metals from soil and rocks.
• Deforestation - Occurs when trees are cut down without being replaced.
• Bad Farming - It is refered to as excessive fertilizer and irrigation use.
• Kaingin - It is the practice of cutting down trees and burning them to clear land for cultivation, exposing the land to air and water and making the soil prone to erosion.
• Landslides - It can occur as a result of erosion.
• Erosion - it has a significant impact on plants, animals, and humans.
• Building dikes of stones or logs - It may be used to slow down water and prevent water from flowing out.
• Contour Plowing - Is a farming technique where the soil is plowed following the contour or shape of the land. It is one of the ways to minimize water runoff.
• Crop Rotation - Is a method of planting in a series of different crops in the same area in sequential seasons. It maintains soil fertility and controls insects and pests.
• Reforestation - it helps prevent soil erosion with the help of it's roots that hold the soil in place.
• Riprapping - Is building ripraps or chunks of stones or rocks arranged on the edge of the slope. This serves as a foundation and a ridge to control soil erosion.
• Strip Cropping - the plants are arranged in strips of alternate bands of row crops and cover crops. Grasses prevent the soil from going downhill.
• Terracing - Terraces are flat areas built on the mountainsides. Since it is flat, it prevents the soil from going down easily.
• Windbreak - planting rows of trees or bushes is another way of preventing soil erosion. These plants act like fences or walls. They block the force of the wind.
• Wind Disturbance - It refers to the disruption of the stable condition of the atmosphere.
• Tropical Cyclone - is a weather disturbance characterized by a big mass of wind and rain whirling around a center of low pressure called the eye.
• Hurricanes - In the Atlantic/Eastern Pacific oceans
• Typhoons - in the western Pacific
• Cyclones - in the Indian Ocean
• Tropical Cyclones - They form when warm air moves over the surface of the ocean, creating a massive amount of water vapor.
• Tropical Cyclones - They weaken as they reach land, because of the loss of the source of heat, which is warm air from the ocean. And this reduces their wind speed.
