What is the hydrosphere primarily composed of?
gas
rock
water
magma
Aquifers are sources of
silica, which is used to make glass and paper products
oil, which is drilled from the aquifer and used to power homes.
saltwater, which is pushed through turbines to make energy.
freshwater, which is used for drinking, bathing, and watering crops.
Herman wants to make a list of things included in the hydrosphere. Which of the following should he add to his list?
mountains
oceans
ozone
trees
Which Earth system is described by the list?
• Covers majority of surface
• Forms relatively thin layer
• Composed primarily of water
lithosphere
hydrosphere
atmosphere
asthenosphere
Most of our water is not...
found in oceans
drinkable
salt water
As energy from the Sun hits the ocean, that energy transforms the water in the ocean into
water vapor in the atmosphere
water vapor under the ground
solid ice in the atmosphere
solid ice under the ground
Evaporation in the water cycle is most affected by
sun's energy
earth's rotation
human activities
Earth's landforms
What will happen to the ice caps if the Sun's energy gets stronger?
The ice will become much colder, causing clouds to form less rainfall.
The ice will become water, then the water will become vapor.
The ice will become much harder, causing clouds to form more rainfall.
The ice will become vapor, then the vapor will become water.
Most of Earth's surface is covered by
rocks
craters
water
ice
reservoir with the largest portion of Earth's water
oceans
ice
groundwater
lakes
reservoir with the smallest portion
rivers
lakes
groundwater
ice
There are over 40 million cubic kilometers of freshwater on Earth. Why is water conservation an important issue?
Over 99% of Earth's available water is undrinkable due to its salt content.
The only freshwater that is usable by humans is contained inside living things.
Less than 1% of Earth's freshwater is immediately available for use by humans.
Freshwater is disappearing quickly due to the melting of ground ice and permafrost.
Which freshwater source is available year round, but can sometimes be low quality and more expensive to access?
runoff
oceans
snowmelt
groundwater
What is transpiration?
a process in which plants take in oxygen and expel carbon dioxide
a process in which plants gain water through the leaf epidermis
a process in which plants combine sunlight with water to manufacture food
a process in which plants lose water through the stomata in the leaf

What day did the body of water most likely evaporate the fastest?
Monday
Tuesday
Thursday
Friday
Steven is learning about the Sun in science class. He thinks that the Sun is only important for plants. Is Steven correct?
Yes, only plants use the Sun's energy to make food.
No, some bacteria and protists use the Sun's energy to make food.
No, the Sun is a major source of energy and affects the wind, water, and organisms up the food chain.
Yes, although other organisms benefit from plants, plants are the only organism that benefit from the Sun.
In the water cycle, what is NOT affected by the heat and light energy from the Sun?
water in the soil
water in the ocean
ice on a mountain
rock under a mountain
