Unit 7 Hydrology Review

What follows evaporation during the water cycle? How does this occur?

• Water evaporates into water vapor
• Water vapor condenses and forms a  cloud
• Water precipitates to the ground
• Water runs down into the hydrosphere

The mixing of cold Artic Ocean water with warm surface Atlantic currents off the northwestern coast of Europe causes which effect? (think about Density)

• Sinking of water as it circulates Southwest
• Reversal of current direction back toward the European coast
• Rise in water salinity and upwelling of affected currents
• Rapid evaporation and acceleration of currents toward the pole

What is the Water Table 

• The top of the Saturated Zone
• A water Table 
• The bottom of the Unsaturated Zone
• Permeable

The supply of freshwater under the Earth's surface.

• watershed
• mouth
• headwaters
• groundwater

Approximately what percentage of the water on Earth is freshwater?

• 0.1%
• 2.6%
• 50%
• 97%

Approximately what percentage of Earth's water is SALT water?

• 97 %
• 71%
• 30%
• 3%

What is an aquifer?

• •a human-made channel (pipe, canal, etc.) that is built to move water from  one location to another
• An area below the earth’s surface where the space between rock and soil particles is saturated with water
• a human-made barrier to control and back up water

The continuous process by which water moves from Earth's surface to the atmosphere and back, driven by energy from the sun and gravity

• Evaporation
• Water Cycle
• Transpiration
• Precipitation

What is the main energy source for deep ocean currents that move large volumes of water around the planet?

• heat from Earth's core
• Radiation from the sun
• Tidal effects of the moon
• Motion of tectonic

A change in the pattern of warm ocean currents can cause a climate change by

• releasing thermal energy in irregular spurts
• absorbing thermal energy from the Sun's rays
• moving thermal energy from one place to another
• increasing the ocean's capacity for absorbing thermal energy
