What causes deepwater ocean currents?
Differences in density and salinity of the water cause it to circle and create a current.

What is the Gulf Stream?
The Gulf Stream is one of the strongest ocean currents in the world. It carries warm water from the Gulf of Mexico to northwestern Europe.
What is the difference between an anemometer and a wind vane?
An anemometer measures wind speed. A wind vane measures wind direction.
How does climate change with latitude?
Near the equator, you see warmer climates (mild, dry, tropical. As yougo North or South, the climates get colder and harsher, being severe and polar mainly.
How many years ago was the atmosphere 15% CO2 (carbon dioxide) and less than 1% oxygen?

What is the main difference between a severe and a highland climate?
1. Highland means mountains, severe does not.
2. Severe has warm summers and cold winters, highland is pretty cool/cold year round

If Oregon was unusually sunny in February, what type of weather might we be experiencing?
A high pressure system
What is the California current and how does it affect the climate?
The California current is a cold water current. It brings cold water down the coast of CA. Likely, this makes the climate of CA cooler than it otherwise would be.
What does the Coriolis Effect have to do with prevailing winds?
You meet someone who is interested in moving to Salem, Oregon. Tell me...
1. What climate would they be moving to?
2. Describe the climate for them
In a mild climate, you can expect to see warm/hot summers and cool winters, but not colder than 27F/-3C. It is a moist climate, with precipitation usually falling in the winter or summer.
What is the greenhouse effect?
The gases that exist in the atmosphere absorb and hold thermal energy that should escape from Earth
