​Any questions about the water (hydrologic) cycle?

Multiple Choice

What is the downward movement of water into the soil is called?

• osmosis

• infiltration

• transpiration

• evaporation

• Much of the precipitation that falls on land enters the ground through the process of infiltration and becomes groundwater.

• Groundwater slowly moves through the ground (percolation), eventually returns to the surface through springs, and then flows back to the oceans (surface water).

Groundwater and Surface water

Multiple Choice

What do we call an area in which the spaces between rock particles are filled with air and water?

• Unsaturated Zone

• Saturated Zone

• Aquifer

• Water Table

Multiple Choice

What do we call an area in which all the spaces between rock particles are filled with water?

• Unsaturated Zone

• Saturated Zone

• Aquifer

• Water Table

Multiple Choice

Impermeable materials:

• have an abundance of pores.

• let water in.

• water can not enter the ground

Open Ended

Provide two examples of ground materials that would be considered impermeable:

What is a permeable area?

• It's a material that water can pass through

• This includes soil, sand, gravel, and cracked rock

• If a rock or clay area does not let water in, it is called impermeable.

Multiple Choice

Sand is ___________, meaning that water can pass through easily.

• Permeable

• Impermeable

• Solid

• Soft

Multiple Choice

What type of sediment tends to be the most impermeable?

• sand

• clay

• silt

• rocks

Multiple Choice

An underground layer of rock or sediment that holds water?

• Reservoir

• Aquifer

• The Rock's career

• Watershed

What is an aquifer?

• An area underground that holds a lot of water.

• It is usually made of gravel, sand, and permeable rock.

• People often drill wells into an aquifer to get water for drinking and farming.

Another problem caused by the excessive withdrawal of groundwater is ground subsidence, the sinking of land.

​Subsidence

Multiple Choice

Define subsidence

• The ability to provide help to those that lack food and water

• Supporting your household by gathering water naturally

• sinking of the ground because of underground material movement

• The ability to trap water and use it within your ecological footprint

• The over pumping of wells can cause the underlying salt water to rise into the wells and contaminate the freshwater aquifer

Salt water Intrusion

Open Ended

Provide one example of your NC Water Basin that incorporates a dam, well, or aquifer:

Multiple Choice

It's been raining for weeks and doesn't look like it'll stop anytime soon, you notice the field next to the stadium parking lot is starting to over-fill with water. What water cycle process has ceased and why is no longer occurring?

• Infiltration, the grass is flooding

• Precipitation, it's an impermeable field

• Evaporation, it's a permeable field

• It is what it is

  (please don't select this one)

​Flooding is defined as: “Any high flow, overflow, or inundation by water which causes or threatens damage.
