What are tides that occur when the sun, Earth, and the moon form a 90 degree angle called?
Neap Tides
What are tides that occur when the sun, Earth, and then moon are aligned called?
Spring Tides
What are the difference between levels of ocean water at high tides and low tides called?
Tidal Range
How long does it take for a spot on Earth that is facing the moon to rotate so that it is facing the
moon again?
24 Hours & 50 Minutes
What does the pull of the moon on the part of the ocean that directly faces the moon cause?
It causes the water to bulge at the moon
Why is the gravitational pull on liquids more noticeable than the pull on solids?
It decreases the distance from the moon
How does a breaker form?
Breakers begin to form as a wave approches the coastline. As water depth becomes shallower,
wave height increases
When waves reach the shore, what is transformed to the beach environment?
They interact and slow water down
Where do low tides form?
In areas between high tides
What are high tides?
The bulges that form in Earth's oceans as a result of the moon's gravitational pull are called
high tides
What two forces influence tides?
The sun and the moon influence tides
What are tides?
Tides are daily changes in the level of ocean water
What is the time between the passage of two wave crests (or troughs) at a fixed point?
Wave period is the time between the passage of two wave crests(or troughs) at a fixed point
What is a disturbance that transmits energy through matter or empty space?
Wave
What is the highest part of a wave?
The Crest
What is the lowest part of a wave?
The Trough
What is the distance between two adjacent wave crests or troughs called?
Wavelength
What is the vertical distance between the crest and the trough of a wave called?
Wave Height
How do most oceans form?
When energy is transferred from a source to the ocean water
What happens to water when a wave of energy moves through it?
The energy moves through the water, and so do the waves
Why are waves different sizes?
Some waves might not have enough energy than others
One reason why upwelling is important to ocean life is...
The nutrients that are brought to the surface of the ocean support the growth of plankton
Cold, nutrient-rich water from the deep ocean rises to the surface and replaces warm surface
water in a process called...
Upwelling
2 Weather patterns that El Nino can alter that can cause disasters are...
Flash floods and mudslides
What data do buoys record?
Data about water temperature, air temperature, currents, and winds
One way that scientists collect data to predict El Nino is...
Put a network of buoys anchored into the ocean floor
It is important for scientists to learn as much as possible about El Nino because...
Temperature on the surface can change
Scientists need to study in order to predict the weather changes on land that might be caused by
El Nino...
it's effects on organisms and land
What is La Nina?
A change in the eastern Pacific Ocean in which the surface water temperature becomes
unusually cool
What is El Nino?
A change in the water temperature in the Pacific Ocean that produces a warm current
In what ocean do El Nino and La Nina form?
Pacific Ocean
The climate along the West Coast of the United States is cooler than the climate of inland areas
because of the effects of...
Cold-water currents
