Water Cycle and Drainage Basin Concepts

This video tutorial covers the drainage basin in physical geography, explaining its components such as the source, confluence, tributary, distributary, and mouth. It also defines these terms and explores the hydrological cycle within a drainage basin, including inputs, flows, storages, and outputs. The lesson concludes with questions for students to test their understanding.

• Confluence

• Source

• Mouth

• Tributary

Which part of the drainage basin is defined as the junction where two rivers meet?

• Tributary

• Distributary

• Confluence

• Watershed

What is a tributary in the context of a drainage basin?

• The origin of the river

• A small channel flowing into the main channel

• The end of the river

• A small channel flowing out of the main channel

What is the opposite of a tributary?

• Source

• Mouth

• Distributary

• Confluence

What is the primary input in the drainage basin hydrological cycle?

• Runoff

• Infiltration

• Precipitation

What is the process called when water moves from the surface to the soil storage?

• Runoff

• Percolation

• Infiltration

• Evaporation

Which storage type involves water being held in vegetation?

• Soil storage
