Ocean Zones
The only ocean zone where plants can grow
sunlight zone
The movement of air across the ocean's surface
surface current
A rhythmic movement that carries energy through matter and space
wave
Trade winds are located
just north and south of the equator
What are the top three ocean zones in order from highest to lowest
sunlight, twilight, midnight
3/4 of the ocean is found in the
abyss
wind
highest point of a wave
crest
This type of water is more dense and sinks
cold water
What are the bottom two zones of the ocean in order from highest to lowest
abyss, trenches
Humanities least explored place
trenches
Acts as barriers to major surface currents
continents
lowest point of a wave
trough
a giant wave usually caused by an earthquake beneath the ocean floor
tsunami
What words would you label the top of the wave and the bottom of a wave?
crest, trough
Name the 3 zones with no light
trenches, abyss, midnight
Deep currents are caused by
differences in density of ocean water
the height of a wave's crest
amplitude
the most common place for a tsunami to occur
ring of fire
What would you label the horizontal distance between waves that are next to each other?
wavelength
The midnight zone is divided into two zones called
abyss and trenches
Three factors that control surface currents
air currents, Earth's rotation, location of the continents
What 3 things cause waves?
wind, earthquakes, gravitational forces of the moon and the sun
the movement of wind and water to the right or left that is caused by Earth's rotation
Coriolis effect
What would you label the vertical distance between the crest and the trough
wave height
