Term
How is the wind produced?
Definition
It is produced by the uneven heating of the Earth's surface by the sun.
Term
What is the process that creates convection currents?
Definition
They are created by a cyclic movement of cool and hot moisture (liquid and gases) that sinks or rises due to the density of each particle.
Term
How is thermal energy transferred though the atmosphere?
Definition
The movement of particles (liquid and gases) from one location to another based on the density of each particle.
Term
Why do many ocean currents begin Equator?
Definition
Water farthest from the poles gets the hottest
Term
Why is the following not a good model of how ocean currents are generated: a student heating salt water on a beaker on a hot plate?
Definition
Because oceans are heated from the top not from the bottom like heating water on hot plate does
Term
The energy that generates wind comes from what source?
Definition
Solar radiation
Term
The convection current called seabreeze is formed when air sinks over the ocean, blows onto the land, then rises. What is the best explanation for why this occurs?
Definition
During the day, the sun's energy heats up the land faster, which makes the air above it warmer
Term
Which of the following changes would eliminate the energy source that generates the convection currents in the ocean?
Definition
Blocking off of solar radiation
