Environmental Unit 5 Review

Temperature inversions are when ...

• The surface temperature drops causing the air above it to be a lower temperature than the much warmer air above it

• When air circulates in around causing warm air to rise and cold air to fall

• The surface temperature heats up causing the air above it to be a higher temperature than the much colder air above it

• When the sun's rays heat the planet and the heat is trapped by our atmosphere

El Nino causes ....

• Massive amounts of tornados in Oklahoma

• The northeast to get much hotter than normal

• The southwest to get lots of extra rain

• The southeast to get lots of extra rain

What is the purpose of succession?

• To help the circle of life

• To renew an ecosystem back to its full potential (usually with grass, bushes, and trees)

• To destroy ecosystems and let them come back weaker than before

• To make life inhabit places that cannot support it

Secondary succession takes an ecosystem back to just having soil, what grows after that?

• trees, then bushes, then grass, then soil, then moss/lichen

• Trees, then bushes, then grass

• Moss/Lichen, then soil, then grass, then bushes, then trees

• Grass/Weeds, then bushes, then trees

Breaking News! A new island has formed off of Hawaii! What must occur for it to become an ecosystem?

• Secondary Succession

• Aquatic succession

• Primary Succession

• Ferns must grow

What is caused when a group of compounds (mainly carbon) trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present.

• CO2 emissions

• A sauna

• Climate Change

• Global Warming

The main human activity that releases greenhouse gases is

• using bottled water

• burning fossil fuels

• texting on cellphones

• eating meat

How is global warming measured?

• Average temperature around the world going up

• Average temperature around the world going down

• When people start wearing tank tops instead of tshirts

• When your teacher's tan is year round

Eutrophication is defined as excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen. What are these areas called?

• Great fishing grounds

• Hot Springs

• Dead Zones

• The end of Bubba Gump Shrimp Co.

Nitrogen and phosphorous are the nutrients that when washed into the water, can cause algae blooms (eutrophication)

• TRUE

• FALSE
