Water Distribution
All water sources can be grouped as either saltwater or freshwater. What water body holds majority of the Earth's saltwater?
Ocean
What is the water cycle?
The continuous movement of water through the Earth and Atmosphere.
What is Ocean Topography?
The heights, depths, and surface of the Ocean Floor.
What is a tide?
The periodic rise and fall of the water level in the ocean
What is the most likely cause of ocean waves?
Surface Winds
Where is most of our fresh water on Earth located?
Glaciers
How are oceans connected to other bodies of water?
The water cycle. All bodies of water are linked through evaporation and precipitation.
Which number shows a seamount?
4
What force causes ocean tides to occur?
The gravitation pull of the Moon
What type of wave is caused by underwater earthquakes?

Where is the second most amount of freshwater located? This is where we get most of our freshwater for drinking, bathing, and watering crops.
Groundwater
Energy from the Sun causes liquid water to turn into water vapor through a process called _______________.
Evaporation
Which number shows a trench?
7
Spring Tide
Denisty drives deep ocean currents. What two factors influence ocean density?
Salinity and Temperature
What percentage of Earth's water is not safe to use as drinking water? (Percentage of saltwater)
97%
Energy from the Sun also causes water to move through a plant and evaporate from its leaves. This process is called _______________.
Transpiration
#2 on the chart shows what feature?
The ________ tide is the tide with the least depth difference between low and high tide.
Neap
How does temperature affect ocean currents?
Cold water is dense and will sink. As the water warms up, it becomes less dense and will rise to the surface.
Put the following in order from largest freswater source to smallest freshwater source:
Groundwater, Rivers, Lakes, Glaciers
1. Glaciers
2. Ground Water
3. Lakes
4. Rivers
What three stages of the water cycle necesarry for it to rain?
#3 on the chart shows what feature?
Abyssal Plain
Spring Tide occurs twice a month when the _______, __________, and _________ are aligned.
Sun, Moon, Earth
Why do surface current turn in opposite directions in the northern and southern hemisphere?
Surface currents are affected by the rotation of the earth, and this is called the Coriolis Effect.
