Oceanography

Terms: ions, cations, anions, parts per thousand, salinity, density, thermocline, gyres, Coriolis Effect
- know the basic composition of sea water
- know where the chemicals in sea water come from
- how the oceans are layered and what causes the layering
- how can the salinity of sea water be changed?
- know the major Atlantic and Pacific gyres and their direction of movement
- know how the Coriolis Effect controls ocean current movement
- know how ocean gyres affect the climates of certain portions of the earth

Atmospheric Sciences Part 1

Terms: troposphere, stratosphere, mesosphere, thermosphere, ozone, Ozone Layer, Greenhouse Effect, Greenhouse gases, Electromagnetic Spectrum, UV light, visible light, infrared light, seasons, solstice, equinox, axial tilt, solar angle
- what is the composition of the atmosphere?
- what is the structure (layering) in the atmosphere and how is it determined?
- how and where does ozone form in the atmosphere?
- how the Greenhouse Effect works
- what causes the seasons and when do they occur?

Atmospheric Sciences Part 2

- know how relative humidity is calculated
- what happens to air when it reaches it’s dewpoint temperature
- know how a barometer works
- the factors that control climate
- what conditions causes air to reach its dew point temperature
- know the processes that cause air to raise
- how to predict wind direction
- the processes that give Laredo it’s seasonal weather
