Water Resources and Watersheds

The video covers the concept of watersheds, explaining how water exists in various forms and moves through different terrains due to gravity. It discusses global and North American watersheds, highlighting the role of continental divides. The video also examines factors influencing water movement, such as soil permeability and human activities like deforestation and dam construction. It explains aquifers, their importance, and challenges like over-extraction. The video concludes with a discussion on the Keystone XL pipeline and its potential impact on the Ogallala Aquifer.

What are the three forms in which water exists on Earth?

• Solid, liquid, and plasma

• Liquid, gas, and plasma

• Gas, plasma, and solid

• Solid, liquid, and gas

What is a watershed?

• An area of land where all water drains to a common location

• A region with no water flow

• A type of water storage tank

• A type of water purification system

Which of the following is NOT a characteristic that influences water movement in a watershed?

• Soil permeability

• Geologic features

• Flora present

• Air temperature

Which watershed is known for its significance to agriculture in the United States?

• The Puget Sound Watershed

• The Hudson Bay Watershed

• The Mississippi River Basin

• The Great Basin

What is an endoreic watershed?

• A watershed that only exists in deserts

• A watershed that has no water

• A watershed that is contained on land

• A watershed that drains into the ocean

How does soil rich in clay affect water movement?

• It increases water permeability

• It decreases water permeability

• It has no effect on water movement

• It allows water to move faster

What human activity can alter the movement of water through a watershed?

• Reducing soil erosion

• Increasing rainfall

• Constructing dams

• Planting more trees

What is an aquifer?

• A large lake above ground

• Underground soil and rock saturated with water

• A type of water purification system

• An underground open space filled with water

Why is the Ogallala Aquifer significant?

• It provides water for agriculture and drinking

• It has the fastest recharge rate

• It is the smallest aquifer in North America

• It is located entirely in Canada

What was a major concern regarding the Keystone XL pipeline?

• It would improve water quality

• It could contaminate the Ogallala Aquifer

• It would increase water levels in the Ogallala Aquifer

• It would decrease oil production
