Water Basics
How much of Earth's water is freshwater that is readily available for human use?
1%
True or False: Ocean currents can carry warm water to locations, warming them up.
What causes waves on the surface of the ocean?
the wind
The process where water from plants enters the atmosphere is called what?
Transpiration
What causes tides on Earth?
The gravity of the sun and the moon
Name where most of Earth's water is found (ocean, glacier, groundwater, or atmosphere).
Oceans
What percentage of Earth's water is in the oceans?
97%
Which factor in an experiment could affect the density of water (temperature, salt, or both)?
Both
List three main processes in the water cycle
Evaporation, condensation, precipitation
How many high tides are in a day?
Two
What do we call the process where water vapor becomes liquid on a cool surface (example: droplets on a cold bottle)?
Condensation
Which makes ocean water denser: increased salinity or decreased salinity?
Increased Salinity
True or False: Surface currents are caused mainly by wind, while deep currents are caused by differences in density.
True
Put these in the order they happen in the water cycle: Precipitation, Evaporation, Condensation.
Evaporation, Condensation, Precipitation
What causes waves? What causes bigger waves?
Wind, and the stronger and longer it blows
Explain briefly why condensation formed on the outside of the cold bottle left on the counter.
The warm water vapor touches the cold bottle and condenses into droplets
Explain where most of Earth's global water is concentrated and why that matters for freshwater availability.
Most water is in the ocean and is too salty
When temperature increases, density...
decreases
What process forms clouds
Condensation
What type of tide occurs when the Sun, Moon, and the Earth are in a Straight line?
Spring Tide
Identify two places where freshwater is stored on Earth
lakes, rivers, aquifers, ice caps
What do we call the "underwater rivers" that are in the Ocean?
Currents
Name 5 Oceans
the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic oceans
What is the process of raining, snowing, or hailing?
Precipitation
What is a Neap tide?
When the Sun, Earth, and the Moon are at a Ninety degree angle
