4.1 Waves
DOUBLE JEOPARDY!!!!
Because the ocean floor has gradual slope, this type of wave will steepen until the crest becomes unstable and gently spills over.
What is spilling wave
What kind of tides occur at full and new moons, when the sun, moon, and Earth make a straight line?
What are Spring tides
What types of currents make up the majority of all currents in the ocean?
What are deep currents
Which type of breaker would travel over a moderately steep slope or have a sudden depth change, where the crest of the wave becomes much steeper, curls over, and drops?
What is plunging wave
What is it called when there is one high and one low tide per day?
Diurnal
These currents occur due to the rising of cold, nutrient rich water and benefits coastal ecosystems
What are upwelling currents
What do you call the highest point on a wave
what is crest
What has the greatest influence on tides?
What is the moon
These currents occur parallel to the shore and can cause erosion
what are longshore currents
What kind of wave can be described as small waves with a short wavelength caused by surface tension?
what is capillary wave
What do we call the largest waves with a long wavelength and a large fetch, usually caused by seismic activity?
What is tsunami waves
How do tide pools affect marine organisms?
- organisms must adapt to harsh environments (withstanding high and low tides along with crashing waves)
DOUBLE JEOPARDY!!!!!
Describe what happens to swimmers if they get caught in a rip current and how to escape from it.
- swim out of it
- DON'T PANIC
- call for help
