Questions and CORRECT Answers
Heat Capacity - CORRECT ANSWER - The amount of heat energy required to raise the
temperature of a substance by 1*C
Role of heat capacity in currents regulating coastal communities - CORRECT ANSWER -
Water stores lots of heat currents transport this heat across the earth
4 factors that affect ocean surface currents - CORRECT ANSWER - Wind, Temperature,
Corialis Effect, Land Masses
Factors cause convection currents - CORRECT ANSWER - Caused by differences in
water density
Convection Currents related to upwelling - CORRECT ANSWER -
Gyre - CORRECT ANSWER - Naturally occurring vortex of wind and currents that rotate
in a clockwise direction
Gyres help create the North Pacific Garage patch - CORRECT ANSWER - Gyres bring all
the trash and garbage towards the middle and stays there
Lunar Day - CORRECT ANSWER - The period of time it takes for the earths moon to
complete one full rotation on its axis 24 hours,50 mins
Spring Tide - CORRECT ANSWER - The greatest distance between high and low water
, Neap Tides - CORRECT ANSWER - Especially Low, Sun and Moon oppose
How many Spring & Neap tides occur in a lunar month - CORRECT ANSWER - Two sets
of spring tides & Two sets of neap tides
Diurnal - CORRECT ANSWER - When there is one high tide and one low tide
-Gulf of Mexico
Semi-Diurnal - CORRECT ANSWER - Two high and two low tides Same Height
-East Coast
Mixed Semi-Diurnal - CORRECT ANSWER - Two unequal highs and two unequal lows
-West Coast-Pacific
How do organisms adapt to living in the rocky shore intertidal zone? - CORRECT
ANSWER - By migrating to an underwater area, restricting activities, and attaching more
firmly to rocks, keep from drying out "desiccation", thermal stress, high salt
How do organisms adapt to living in the sandy beach intertidal zone? - CORRECT
ANSWER - Bury themselves deep in the sand to avoid predators and form drying out in
the sun
Meiofauna - CORRECT ANSWER - organisms living in soil and aquatic sediments
In which intertidal zone would it be part of the food chain? - CORRECT ANSWER -
sandy intertidal zone, high grains of sand, worms, mollusks, arthropods
How do waves move? - CORRECT ANSWER - waves are created by energy passing
through water causing it to move in a circular motion
