Warm Up # 9 ¾ • What are the four major limiting factors in

an open ocean biome?

• As you get deeper in an open ocean, what happens to the:• Nutrients• Sunlight• Temperature• Oxygen

• Describe the intertidal zone biome. How are certain species able to live there (how do they adapt)?

Chapters 7&8 Review

Air Patterns• Warm air rises, cold air

falls

• hot and cold air mix = temperature inversion• Storms, tornadoes, Marine Layer

• Warm Front – rush of warm air under cold air• Result: Storms (inversion)

Air Pressure and Extreme Weather

Pressure: Air likes HIGH to LOW

• Low High = storms• High Low = clear

sky

Warm water + warm wind:• Hurricanes – Atlantic• Typhoons – Pacific

Relating Heat and Humidity• Humidity = moisture in air

Cool air falls, warms

Warm air rises, cools

Hadley and Ferrel = Cold, Dry Air FALLING DESERT

Ferrel and Polar = Warm Moist Air RISING BOREAL FOREST

Other Related InfoOzone Layer/Thermal Cap•Keeps heat in, keeps UV rays out

Rain Shadow Effect •one side of mountain = moist •other side of mountain = dry

Upwelling•Cycles nutrients/cold water up

•El Nino – less upwelling/warmer waters
