Drainage Basin System

What is a drainage basin?

• A mountain range

• An area of land where all the surface water converges to a single point

• A type of kitchen sink

• A large body of water

Explain the concept of watershed in the context of a drainage basin system.

• A watershed is a type of water filter used in drainage systems.

• A watershed is a type of boat used for navigating through drainage basins.

• A watershed is a type of weather phenomenon that causes flooding in drainage basins.

• A watershed is an area of land where all the water that falls within it drains into a common outlet, such as a river, lake, or ocean.

What are the main components of a drainage basin system?

• Rivers, streams, lakes, and wetlands

• Cities, towns, villages, and farmlands

• Oceans, glaciers, volcanoes, and plateaus

• Mountains, deserts, forests, and plains

Describe the process of surface runoff in a drainage basin.

• Surface runoff is the movement of water from the ocean to the land.

• Surface runoff is the flow of water underground into the soil.

• Surface runoff is the process of water evaporating from the land surface.

• Surface runoff is the flow of water over the land surface and into streams, rivers, and lakes.

How does infiltration contribute to the drainage basin system?

• It causes water to evaporate from the soil

• It leads to excessive flooding in the drainage basin

• It has no impact on the drainage basin system

• It allows water to enter the soil and recharge groundwater.

What role does precipitation play in the functioning of a drainage basin system?

• It leads to the formation of solid rock in the drainage basin system.

• It contributes to the water input of the drainage basin system.

• It causes the drainage basin system to shrink.

• It has no impact on the drainage basin system.

Explain the concept of streamflow and its significance in a drainage basin system.

• Streamflow is the flow of water in a natural or artificial channel, such as a river or stream, and it is significant in a drainage basin system as it determines the amount of water available for various uses, impacts water quality, and influences the overall ecosystem.

• Streamflow is the flow of air in a natural or artificial channel, such as a river or stream, and it is significant in a drainage basin system as it determines the amount of water available for various uses, impacts air quality, and influences the overall ecosystem.

• Streamflow is the flow of sand in a natural or artificial channel, such as a river or stream, and it is significant in a drainage basin system as it determines the amount of water available for various uses, impacts water quality, and influences the overall ecosystem.

• Streamflow is the flow of lava in a natural or artificial channel, such as a river or stream, and it is significant in a drainage basin system as it determines the amount of water available for various uses, impacts water quality, and influences the overall ecosystem.

Discuss the impact of human activities on the drainage basin system.

• Increased erosion, pollution, and changes in water flow

• Decreased erosion, clean water, and stable water flow

• Positive impact on erosion, pollution, and water flow

• No impact on erosion, pollution, or water flow

What are the different types of drainage patterns found in a drainage basin system?

• Dendritic, parallel, trellis, rectangular, and radial patterns

• Circular, spiral, linear, grid, and random patterns

Explain the concept of river discharge and its importance in the drainage basin system.

• River discharge is the temperature of the water in a river, and it is important in the drainage basin system as it affects the types of plants that can grow along the riverbanks.

• River discharge is the speed at which a river flows, and it is important in the drainage basin system as it determines the color of the water.

• River discharge is the volume of water flowing through a river at a given point, and it is important in the drainage basin system as it affects the overall water balance, sediment transport, and the shaping of the landscape.

• River discharge is the amount of fish found in a river, and it is important in the drainage basin system as it provides food for the local wildlife.
