What is 6th water cycle?
The constant movement of water from the Earth to the atmosphere and back to the Earth through the process of evaporation, condensation and precipitation is known as the water cycle.
What happens if it rains heavily Class 6?
(2) Heavy rains (or excessive rains) may cause floods. Heavy rains lead to too much rise in the level of water in rivers. The flood water may submerge cities , villages, crop fields, and forests causing damage to property (houses, etc.), human life, domestic animals, standing crops, and wild animals of the forests.
How is rain useful to us Class 6?
How is rain useful to us? Rains bring relief by cooling the environment after hot summer days. The sowing of many crops depends on the arrival of rains during monsoon. Rains provide water in the rivers and dams of hydroelectric power plants.
What is the final stage of water cycle?
This is called condensation. Precipitation occurs when so much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow.
Which is the most powerful cause of erosion?
One of the most powerful causes of erosion is water. Water is sometimes called the universal solvent, because it is so effective at dissolving and changing things. Rain and runoff contribute to erosion, as do glaciers, snow, and ice. Ice can be particularly insidious, because it will literally rip rock and soil apart as it expands and contracts.
How does soil erosion affect surface water runoff?
Surface water runoff occurs whenever there is excess water on a slope that cannot be absorbed into the soil or is trapped on the surface. Reduced infiltration due to soil compaction, crusting or freezing increases the runoff.
How is erosion a part of the geologic process?
Erosion is a continual process, and it can be caused naturally or through artificial means. While many people associate erosion with negative things like land slides and poor soil conditions, it is an important part of the geologic processes which make the Earth what it is.
How are sediments disintegrated by weathering and erosion?
Sediments were described in the Rocks chapter. With weathering, rock is disintegrated. It breaks into pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments. Erosion is the next chapter’s topic.
