What is transpiration? A. Water to gas B. Gas to water C.
Evaporation from plants D. Water falling from clouds
Slide 3
Name the two factors that drive the water cycle. A. Water B.
Solar energy C. Precipitation D. Gravity
Slide 4
Why is water a renewable resource? A. Water is constantly being
recycled, filtered and renewed through the water cycle.
Slide 5
Explain how solar energy helps drive the water cycle. A. Solar
energy (sunlight) causes large bodies of water to heat up. This can
cause evaporation, which leads to the condensing of clouds,
etc
Slide 6
Explain how gravity helps drive the water cycle. A. Without
gravity, water would not fall back to Earth in quantities needed to
support life.
Slide 7
Why are the oceans and the atmosphere considered carbon sinks?
A. The ocean contains calcium carbonate and carbon dioxide. B. The
atmosphere contains carbon dioxide.
Slide 8
Name 3 factors that might cause a water table to RISE. A. Rains
B. Flooding C. Replacing used water with recycled water D. More
permeable material E. Snowmelt in the spring F. Damming a river
(flooded side)
Slide 9
What is the difference between a well and a spring? A. A well
is manmade, while a spring is a natural formation
Slide 10
What is the difference between a deep current and a surface
current? Deep current: is in the deep zone and is caused by
temperature changes Surface current: is in the surface zone and is
caused by wind patterns and Earths rotation (Coriolis Effect)
Slide 11
Name three gases found dissolved in ocean water. 1. Nitrogen 2.
Oxygen 3. Carbon dioxide
Slide 12
Which ocean layer has the lowest density? A. Deep zone B.
Thermocline C. Surface zone D. Saturation zone
Slide 13
Name three solids found dissolved in ocean water. A. Chlorine
B. Sodium C. Magnesium D. Potassium
Slide 14
Name three factors that might cause a water table to DROP A.
Drought/no rainfall B. Damming a river (dried side) C. Not
replacing used water with recycled water D. Overuse by humans Too
many wells Irrigation Industrial needs
Slide 15
What is porosity? A. The ease at which water can move through a
material B. The amount of space found in the pores of a material C.
A permeable rock that holds and stores water D. A manmade hole dug
to access groundwater
Slide 16
Define salinity. A. The amount of salt dissolved in a
liquid
Slide 17
How might human use affect the water table? A. If humans use
more water before it can be replenished, the water table (and water
supply) might drop!
Slide 18
How might weather affect the depth of the water table? A. If
there is too much rain, it can cause a rise in the water table. If
there is not enough rain, then the water table may drop.
Slide 19
What is a recharge zone? A. Any area where water can pass
through rock B. Any area where water can pass the water table C.
Any area where water can pass through permeable rock and replenish
an aquifer D. Any area where water passes through permeable rock
and leaves an aquifer
Slide 20
What is the difference between an ordinary well and an artesian
well? A. An ordinary well is one where people must actively get the
water out. An artesian well is one where water naturally comes out
due to underground pressure.
Slide 21
Which ocean zone has the densest water? A. Surface Zone B.
Thermocline C. Aeration Zone D. Deep Zone
Slide 22
Why does the deep zone have the saltiest water? A. The deep
zone has the saltiest water because water with high salinity is
very dense. This dense water will sink below the less dense (and
less salty) water.
Slide 23
Define permeability A. The ease at which water can move through
a material B. The amount of space found in the pores of a material
C. A permeable rock that holds and stores water D. A manmade hole
dug to access groundwater
Slide 24
What is a current? A. A stream of water flowing through an
ocean. B. A stream of water flowing through the surface zone C. A
stream of water flowing through the deep zone D. An edible fruit
typically pureed and used in many different desserts
Slide 25
What is a carbon sink? A. A reservoir that holds and stores
water B. A reservoir that holds and stores carbon compounds C. A
reservoir that holds and stores salts D. A layer of permeable rock
that holds and stores water
Slide 26
Name three sources for the solids found in ocean water. A.
Erosion of rocks B. Underwater volcanic eruptions C. Chemical
reactions between seawater and magma
Slide 27
Why does the surface zone have the warmest temperature? A. The
surface zone has the warmest temperature because warmer water is
less dense than colder waters. This means that the less dense water
will stay near the top while the more dense water will sink to the
bottom.
Slide 28
What is buoyancy? A. A substances ability to float in another
substance B. The amount of salt in a liquid C. The amount of mass
in a given volume D. A substances ability to sink
Slide 29
Name three sources for the gases found in ocean water. A.
ATMOSPHERE B. Underwater volcanic eruptions C. Living
organisms
Slide 30
Why does the deep zone have the coldest temperature? A. The
deep zone has the coldest water because cold water is very dense.
Dense water tends to sink to the bottom while less dense waters
will be found in the top layers.
