Water Cycle
The main energy source that drives the water cycle.
The Sun
Objects that are more dense than water will do this.
Sink
The main force that drives surface ocean currents.
Wind
One example of how humans pollute the hydrosphere.
TBD
The continuous movement of water through Earth's systems.
The Water Cycle
The process where liquid water turns into water vapor.
Evaporation
An object will do this if it is less dense than the liquid around it.
Float
Warm water near the equator is less dense, so it does this — helping drive surface currents toward the poles.
Rises
Structures built to control river water flow and prevent flooding.
Dams and Levees
The amount of matter in a given amount of space.
Density
Water vapor cools and turns back into liquid droplets, forming clouds.
Condensation
Between warm water and cold water, this one is more dense.
Cold Water
Deep ocean currents are driven by differences in temperature and _____.
Salinity
These natural areas filter water and absorb floods but are often drained or removed by humans.
Wetlands
Cold, salty water does this to form deep ocean currents.
Sinks
The process by which plants release water vapor through their leaves.
Transpiration
Between salt water and fresh water, this one is more dense.
Salt Water
The name for the worldwide system of deep ocean currents.
The Global Ocean Conveyor Belt
One negative effect of building a dam on a river.
TBD
Water that flows over land into rivers and lakes after precipitation.
Runoff
Water that flows downhill to a nearby body of water.
Runoff
Less Dense
Cold, salty water is denser than warm water — so it will ______.
Sink
Name two solutions humans can use to protect the hydrosphere.
Any two: water conservation, reducing pollution, sustainable farming
The Name that idescribes all of Earth's water — oceans, rivers, glaciers, and groundwater.
The Hydrosphere
