Water that flows in rivers
Water that fills tiny gaps between soil and sediments underground
Water vapor in the atmosphere
Water found in oceans
What defines the water table?
The surface of a river
The depth at which soil is saturated with water
The level of groundwater in aquifers
The boundary between wetlands and dry land
Which of the following describes an aquifer?
A layer of impermeable rock
A layer of saturated, permeable rock
A water source above the water table
A type of wetland
What is an aquitard?
A body of water above the surface
An impermeable layer that prevents water flow
A type of spring
A well for pumping water
What are wetlands primarily characterized by?
Dry soil and limited vegetation
Water present at least part of the year
High levels of salinity
Urban development
What caused the Dust Bowl in the 1930s?
What is the role of an artesian well?
It collects rainwater
It uses natural pressure to bring water to the surface
It filters pollutants
It is used for irrigation
What happens when aquifers are pumped faster than they can recharge?
They overflow
They become more saturated
They could run dry
They cause floods
What is the primary benefit of riparian zones?
They provide urban development opportunities
They stabilize riverbanks and improve water quality
They promote deforestation
They reduce biodiversity
How do anoxic soils affect carbon in wetlands?
They promote decomposition
They increase carbon cycling
They slow decomposition, causing carbon buildup
They have no effect on carbon
Why does water behave differently than other liquids?
It has a high boiling point
It is a polar molecule
It is a gas at room temperature
What is cohesion in relation to water?
Water's attraction to other substances

The process of water evaporating
Water's ability to freeze
What is the hydrologic cycle also known as?
The nitrogen cycle
The water cycle
The carbon cycle
The soil cycle
What is the primary role of watersheds?
To store groundwater
To drain into a specific body of water
To prevent flooding
To filter pollutants
What is an estuary?
A freshwater river
The area where freshwater meets the ocean
A source of groundwater
A type of wetland
How does acid rain form?
Through evaporation
From fossil fuel combustion creating acidic components
From natural mineral deposits
From excessive rainfall
What happens to trees when acid rain leaches minerals from the soil?
They grow faster
They struggle to grow
What is the effect of shade from trees in riparian zones?
Increases water temperature
Reduces erosion
Decreases biodiversity
Causes pollution
What is transpiration?
Water vapor leaving plant leaves
Water seeping into the soil
Water evaporating from rivers
Water flowing over land
Which of the following describes the benefits of riparian zones?
They only provide habitat for fish
They improve water quality and reduce erosion
They promote urban development
They have no significant ecological impact
