diurnal tides(what occurs & where)

1 high and low tide(Gulf of Mexico)

semidiurnal tides

2 "equal" high & low(East Coast)

mixed tides

2 unequal highs & lows per day(west/pacific coast)

What is heat capacity?

Ability to resist heating or cooling

Importance of Peru Current

Brings nutrient rich water along the coast

What affects surface currents?

Coriolis effect, landmasses, & Earth's rotation

What causes the Coriolis effect?

Earth's rotation

What are gyres?

Large, circular oceanic currents.

Where do tsunamis typically occur?

Pacific ocean and Indonesia

How do salinity and temperature affect water density?

Salty and cold water sinks and vise versa

Distinguish between spring and neap tides.

Spring tides are

What is the main cause of tides?

The gravitational pull of the moon

How do ocean currents affect coastal climates?

Warm currents create warmer climate, cold currents create a cooler climate

What are the causes of tsunamis?

active submarine earthquakes

What are the mathematical formulas that describe orbital wave characteristics?

atomic orbital

How do landmasses affect surface currents?

can deflect them from their original path

What causes deep water currents?

caused by differences in temperature and salinity(density)

Which way do surface currents rotate in the Northern Hemisphere?

clockwise

Which way do surface currents rotate in the Southern Hemisphere?

counterclockwise

Distinguish between deep water waves and shallow water waves.

deep water waves are further in the ocean while shallow water waves are closer

Describe what happens when a wave approaches the shore.

forms larger waves which contribute to more energy

what causes surface currents?

global winds

Explain the movement of water in a wave

in a circular motion however the horizontal movements are energy

What is the Great Pacific Garbage Patch, what is the primary kind of garbage, and what effects does it have on organisms?

micro plastics, the organisms ingest and can affect their health

deep water waves

no interference with ocean bottom(wind generated)

What other factors affect tides?

position of Earth and sun; shape of the shoreline

What are the 3 types of breakers?

surging, plunging, and spilling

Tidal bores

the wall of water that moves up to a certain low lying river due to an incoming tidal wave

Why are currents important?

they influence global weather and climate patterns

shallow water waves

touch the sea floor and infer with waves orbital motion(controlled by water depth)

The gulf stream carries_________water and wind and the California currents carries_______water and wind.

warm, cool
