How do deep ocean currents form?
The form as warm, dense water sinks and flows beneath cold ocean water.
They form as cold, dense water sinks and flows beneath warm ocean water.
They form as warm, dense water sinks and flows with other warm ocean water.
The wind blows causing the deep ocean currents.
Surface currents always move water in which directions?
clockwise
counter-clockwise
vertically
horizontally
Ocean currents have an effect on which two things
climate and weather
land and sea
temperature and density
equator and poles
Explain the difference between high tide and low tide.
High tide is when the water level is at its highest, and low tide is when it's at its lowest.
High tide occurs due to the gravitational pull of the moon, and low tide occurs when this pull is weakest.
How do gravitational forces from the moon and sun contribute to tides?
Tides occur due to the magnetic pull of the moon and sun, not gravitational forces.
Tides are caused by the rotation of the Earth, not gravitational forces.
Gravitational forces from the moon and sun create earthquakes, affecting tides.
Gravitational forces from the moon and sun create bulges in the Earth's oceans, resulting in tides.
Why do tides occur twice a day?
Tides occur due to changes in atmospheric pressure
Tides are a result of underwater volcanic activity
Tides are caused by the rotation of the Earth
Gravitational pull of the moon and sun on Earth's oceans
What effect does the moon have on the Earth's oceans?
It causes the oceans to freeze and thaw.
It has no significant effect.
It influences the ocean's tides.
It changes the chemical composition of seawater.
What role do ocean currents play in climate regulation?
They have no impact on climate
They transport heat from the equator to the poles
They increase the temperature of the ocean
They decrease global temperatures by absorbing heat
The rise and fall of Earth's waters on its coastlines are called
currents
tides
waves
gravity
A large stream of water that moves through the ocean is called a
longshore drift
current
tide
wave
Tides are caused by the interaction and influence of
the Earth
the Sun
the Moon
gravity
wind
Spring tides and neap tides occur in patterns caused by the
phases of the moon
seasons (fall, winter, etc.)
surface currents
deep sea currents
Which type of tides have a larger tidal range due to the Earth, Moon, and Sun forming a line?
High/Low
Spring
Neap

Surface Currents
Why is upwelling important?
Upwelling regulates ocean temperature
Upwelling provides nutrient rich water that sustains life

What is a high tide?
