what is the definition of coriolis effect
a phenomenon that causes fluid, like water and air, to curve as they travel across or above the earths surface
what direction does air and water curve from the equator
to the east
what creates the curve
coriolis effect
what part of the earth gets the most sunlight and what type of heat transfer is this
equatorial regions, radiation
what additional heat transfer happens because of the coriolis effect
convection
how do hurricanes spin in the northern hemisphere? what makes it go in this direction
counter-clockwise, coriolis push
what do hurricanes spin in the southern hemisphere? what makes it go in this direction
clockwise. coriolis push
which two large earth systems are affected by the coriolis affect
air and water
where does warm ocean water come from and how does it get warm
originates near the equator, sunlight
where does cold ocean water come from and how does it get cold
polar regions deep ocean, currents
what are the 5 major gyres
the north atlantic gyre, the south atlantic gyre, the north pacific gyre, the south pacific gyre, the indian ocean gyre
explain how radiant heat transfer works in the gyre system
ocean currents move within their gyres primarily through the process of convection
explain how convection heat transfer works in the gyre system
to the movement of heat in the vertical direction
how warm does ocean water have to be to start a hurricane
above 26 degrees celsius, 79 degrees fahrenheit
explain how the gyre lab was different than the heat transfer lab
it involved ice, the candle was at the end instead of the middle
between which latitudes are the trade winds
NE, SE
between which latitude are the westerlies
30 degrees
between which latitudes are the polar easterlies
60 degrees
know which cells align with which winds
polar cell- polar easterlies
ferrel cell- westerlies
hadley cell- NE trade winds
hadley cell- SE trade winds
explain how radiation effects the atmosphere cells and winds
the moré solar radiation is absorbed and heat is re radiated the more the temp of atmosphere goes up
explain how convection effects the atmospheric cells and winds
lowers surface pressure creating a pressure gradient that tries to correct itself by having air move from higher pressure to the lower pressure area created by rising air
how does the coriolis effect make the wind move in a slant
deflects the direction of the flow of the air and causes the air to flow parallel to the isobars
in the activity, what did the bubbles represent
atmosphere cells
what are the 5 layers of the atmosphere from the earth upward in other
troposphere, stratosphere, mesosphere, thermosphere, exosphere
