Watershed
What is a watershed? How does it function like a funnel?
An area of land where all the water drains into a common body of water. It brings water from the highest point in an area to the lowest point.
What are signs that a local body of water is polluted or unhealthy
Unusual colors, odors, or tastes in the water. You can also check the water's clarity.
True or False: Weathering includes the movement of rock fragments.
False.
What is the chemical formula for water?
H2O
What are the three phases of water?
Solid,Liquid, and Gas
What physical features typically define a healthy watershed?
Good water quality, quantity, and flow; and habitats with diverse aquatic life.
What are the main illnesses caused by polluted water
Cholera, dysentery, hepatitis A, typhoid and polio.
What acts like a "conveyor belt" to move large amounts of sediment?
Glaciers
What force causes precipitation to fall and runoff to move?
Gravity
What is the process called when water vapor changes directly into a liquid?
Condensation
What makes water flow in a watershed?
By soaking into the ground; or by running off the landscape
How can communities prevent polluted runoff from entering lakes?
Natural vegetation buffer along streams that can slow, filter, and store polluted runoff.
What type of climate has the highest rate of chemical weathering?
Hot and wet climates
True or False:Water can turn directly from a solid to a gas.
True
What are clouds made of?
Clouds are made of tiny liquid water droplets or ice crystals.
Who is responsible for managing the health of a watershed
Watershed Managers are responsible for creating,and developing plans for the management of water systems.
How do everyday household items contribute to water pollution?
When chemicals and waste travel down drains, sewage systems, and local waterways.
True or False: Plants only contribute to physical weathering
False.
True or False:the oxygen atom has a positive charge.
False
The process of water evaporating through plants.
What actions can be taken to protect a local watershed?
Throw away trash properly, build a rain barrel,and conserve water.
What is the difference between point and nonpoint source pollution?
Point source pollution comes from a single, knowable source. Nonpoint source pollution is where you don't know the source.
What is the main difference between weathering and erosion?
Weathering breaks down rock, while erosion transports the broken-down sediment to a new location.
Which state of water has the lowest density?
Water vapor
How do clouds form?
Water vapor rises, cools, and turns back into liquid droplets, forming clouds.
