What are the two driving forces of the water cycle?
gravity and the sun
What farm practice can cause nutrient pollution?
Overfertilizing, fertilizing before a lot of rain
What are topographic maps?
They are a way to understand landforms on paper (in a 2D way)
Name one example of a destructive process
weathering, erosion
Name one example of a constructive process
deposition
What process turns liquid water into gas as the Sun's energy heats it up?
evaporation
What specific contaminants can cause nutrient pollution (if there is an excess amount)
Phosphorus, nitrogen (also acceptable: sulfur)
What do contour lines connect?
They connect all points that share the same elevation.
How do destructive processes change Earth's surface?
They break apart or destroy Earth's surface
How do constructive processes change Earth's surface?
Constructive processes build or add to Earth's surfaces
What process turns water vapor into liquid water as gravity pulls it down?
Condensation
What can an excess of nutrients lead to (specifically in the ocean)
It can lead to a dead zone
What do contour lines tell us?
They tell us the change in elevation
What is a landform that is formed by erosion?
Canyon, mountain
What is a landform that is formed by deposition?
River delta
How does the Sun affect the cycling of water?
evaporation of water and/or melting of snow and ice
Describe how nutrients/contaminants cause nutrient pollution in runoff water
If there are too many nutrients (from overfertilization), they get washed away in runoff. These contaminants travel in the runoff water to the ocean, where they can cause dead zones.
How can we find the peak of a mountain on a topographic map?
We look for the smallest circle of contour lines.
Weathering
If more sediment is dropped off at a location, would there be more or less deposition?
There would be more deposition
How does gravity affect the cycling of water?
surface runoff and/or precipitation (or condensation)
How do contaminants enter the water cycle in our atmosphere?
How do we find the difference in elevation between two points?
We subtract the lower elevation from the higher elevation.
What are the two agents (driving forces) of erosion?
Water and wind
Is the relationship between erosion and deposition causal? (cause and effect?)
Explain!
Yes, because erosion causes deposition. You cannot have deposition without erosion.
