Why can we say that there is just one ocean?
because the oceans are all connected together
What is one thing that determines the size of a surface wave?
how long the wind blows
What is the origin of surface currents?
when God created the winds to move across the water
What causes surface currents to move in a circular pattern?
the earth's rotation
The surface currents in the Northern Hemisphere move in what direction?
Clockwise
What are 2 ways to conserve fresh water?

- Give your pet fresh water and use the old water for your plants
- Wash pets outside in the grassy area that also needs water
- Use a water hose instead of a broom to clean driveways

T or F: a surface wave transfers wind energy over a distance without moving any matter
True
T or F: as a surface wave nears land, the top of the wave touches the ocean floor
False
T or F: friction from the ocean floor slows a wave near land, and gravity makes the top of the wave fall
True
Name all 5 Oceans
Pacific
Atlantic
Indian
Southern (Antarctic)
Arctic
T or F: as the surface wave crashes onto land, wind energy transfers to light energy, and some of the energy causes beach erosion
False
T or F: deep ocean currents are affected by how salty the water is in the sand's depth at the ocean floor
False
