What are the 4 steps in the water cycle?
Evaporation
Condensation
Precipitation
Collection
What percentage of the earth's water is fresh water
3 %
What percentage of the earth surface is covered in water?
70-75%
How often does the tide change from low tide to high tide
Every 6 hours
(12 hours between each high tide and 12 hours between each low tide)
What is upwelling
When cold nutrient rich water moves up through convection currents to replace the warm surface water.
What fuels the water cycle (is responsible for it happening)
Heat (Sunlight)
What percentage of earth's water is useable freshwater?
Bonus 200: Where is the rest of the fresh water we can't use located
1 %
Bonus: 2% is locked away frozen in glaciers and groundwater
What are the five oceans of the world
Atlantic, Pacific, Indian, Artic, Southern Oceans
Identify the 4 parts of a wave and what they are.
Crest- highest point on wave
Trough- lowest point on a wave
Amplitude- The height of a wave from crest to trough
Wavelength- the distance or length a wave takes up
What is a convection current?
A current created from temperature differences, in which hot particles move to colder areas and cold particles move to warmer areas creating an endless cycle.
What is the name of the process that releases water vapor from plants into the air
Bonus 300: What is dew point
Transpiration
Bonus: The temperature at which the rate of condensation equals the rate of evaporation
Surface water is fresh water found on earth's surface name 3 places it can be found
Lakes, ponds, rivers, streams, swamps
Match each Ocean to its fact
Southern, Pacific, Indian, Atlantic, Artic,
Largest Ocean
Smallest Ocean
Hottest Ocean
Saltiest Ocean
Surrounds one entire Continent
Largest Ocean = Pacific
Smallest Ocean = Artic
Hottest Ocean - Indian
Saltiest Ocean = Atlantic
Surrounds one entire Continent= Southern
What is a wavelength and how is it measure
The distance of a wave and it's measured from crest to crest or trough to trough.
Which ocean current keeps North America & Europe supplied with warm water year round
Gulf Stream Current
What is the scientific name for the water cycle
Hydrologic cycle
What is an aquifer
An area of rock or sediment that store groundwater and allows it to flow.
What are the two main regions of the ocean floor?
Bonus 400: This first area of the ocean floor is divided into three parts what are those parts
Continental Margin, Deep Ocean Basin
Bonus: Continental shelf, Continental slope, Continental rise.
Frequency is how the number of waves produced in an area over a given amount of time. We can use frequency and wavelength to find wave speed.
Wave speed (v) = wavelength(w) x frequency (f)
If the is wave speed is 20 m/s what is w= meter if
f =4 seconds
Wave Speed is 20 m/s
wavelength is 5
frequency is 4
What causes currents to move in the ocean
Bonus 400: What does thermohaline mean
Wind and salinity differences in the oceans.
Bonus: Temperature and salinity
Normally in the water cycle water changes from solid water turns into a liquid before it can become a gas but, in this process, water turns directly from a solid to a gas what's the name of this process.
Sublimation
What are the 4 reason we need and use fresh water for as humans
Drinking & Cooking (Home Use), Agriculture, Transportation, & Industrial uses (Factories)
Techtonic plate activity creates this on the ocean floor (2 things)
Mid Ocean ridges & Ocean Trench
All four of these events can create tsunamis in the ocean.
Bonus: What is a tsunami
Earthquake, Landslide, Meteorite or comet, Volcano
Bonus: A series of waves that form when a large volume of water is moved up and down in the ocean
Explain the Coriolis effect and what would happen on earth if we didn't have one
The deflection of straight object on earth due to earth's rotation.
Wind and currents would move in Stright line instead of a circular motion
