Water Cycle Quiz Study Material

A student walks across the playground in the morning and the grass is wet, although there was no rain or watering of the grass in the last 24 hours. What caused the grass to be wet?

• Evaporation because the water on the grass is turning into water vapor.

• Transpiration because the plants give off water vapor during photosynthesis.

• Condensation because water vapor collected to form droplets on the grass during the cooler night temperatures.

• Precipitation because water vapor from the sky formed droplets during the cooler night temperatures that fell on the grass.

Which of the following terms is defined as the loss of water as vapor from plants?

• infiltration

• precipitation

• runoff

• transpiration

Which stage of the water cycle is represented by the slope in the glass tank?

• Collection

• Condensation

• Evaporation

• Run-off

Almost three-fourths of the Earth’s surface is covered in water.  This water is a mixture of salt water and fresh water.  The majority of the water is salt water from the ocean and the remaining is fresh water. Glaciers and ice caps make up most of the fresh water, then ground water and lakes, rivers and swamps making up the smallest percent of fresh water. Based on the graph, what does column number 2 represent?

• The total percent of glaciers and ice caps on Earth.

•  The total percent of fresh water on Earth.

• The total percent of salt water on Earth.

• The total percent of water on Earth.

Jenny was investigating the water cycle. She completed the following steps in her investigation:

1. Find a clear plastic aquarium that has a lid.

2. Cut a hole in the lid large enough to fit an insulated cup that is filled with ice.

3. Add water in the bottom of the aquarium to a depth of 2-5 inches.

4. Shine a light source, such as a desk lamp, above the aquarium.

How would the results of Jenny's investigation change if she increased the number of lamps?

• Condensation around the insulated cup would decrease and evaporation within the aquarium would increase.

• Evaporation within the aquarium would increase and condensation around the insulated cup would increase.

• 
  Precipitation within the aquarium would decrease and evaporation within the aquarium would increase.

• Precipitation within the aquarium would increase and condensation around the insulated cup would decrease.

One major problem with the quality of the freshwater found in lakes has been contamination from fertilizers. If the water in lakes becomes unusable for humans, what other sources of freshwater are there and why might this present a problem?

• Other freshwater sources include rivers, icecaps, glaciers, permafrost, and estuaries. This could present a problem because most of the Earth's freshwater is found in lakes.

• Other freshwater sources include rivers, icecaps, glaciers, permafrost, and estuaries. This could present a problem because most of the remaining freshwater is frozen in icecaps, glaciers, and permafrost.

• Other freshwater sources include rivers, icecaps, glaciers, permafrost, and groundwater. This could present a problem because most of the remaining freshwater is frozen in icecaps, glaciers, and permafrost.

• Other freshwater sources include seas, rivers, atmospheric water vapor, and groundwater. This could present a problem because most of the Earth's freshwater is found in rivers but there are not very many rivers on the Earth.
