Earth Science Hydrology Review

Ocean currents are powered by

• Conduction
• Convection
• Radiation

The water cycle is the

• distribution of drinking water on Earth
• unending circulation of Earth's water supply
• recycling water for industrial use
• evaporation of water from Earth's surface

Groundwater is found underground in the zone of 

• aeration
• saturation
• porosity
• permeability

Groundwater flow is affected by the _ of soil.

• porosity
• type
• location
• aeration

Which of the following is not a major source of groundwater pollution?

• sewage
• pesticides
• industrial chemicals
• compost

Permeable rock layers or sediments that freely transmit groundwater are

• springs
• water tables
• rivers
• aquifers

A major cause of floods is

• light rain over a large area.
• increased capacity of stream channels.
• empty space in the zone of saturation.
• no space in the zone of saturation

The term for water evaporating from plants is

• transpiration
• precipitation
• runoff
• infiltration

If evaporation equals precipitations, the water cycle is

• unbalanced
• balanced

An ocean current flowing from the south pole to the equator is most likely a

• warm current
• cold current
