Climate Diagrams
Opener: Ecology Part 1: Basic Ecology
What determines a biome?
What are the two most important factors in determining a biome? WHY are these factors so important?
On a climate diagram, what goes on the x axis? The y axis (2 things)?
In the space below, draw two climate diagrams for a tropical rainforest climate and for a desert climate
What are the other biomes listed in the notes? (Use this section as a word bank for the next half)
Using your notes, determine what kind of biome the climate diagrams below correspond to
Vocab:
Define the following:
Photic Zone
Aphotic Zone
Multiple Choice
1) Where do rain shadows exist?
a) The part of a mountain the receives prevailing winds and heavy rain
b) The region beyond a mountain range that receives dry air masses
c) The region along the equator where precipitation is abundant
d) The region near 30 N and 30 S that receives hot, dry air masses
2) A region receives less than 5 cm of precipitation annually and has temperatures that never drop
below freezing. Which type of biome is present?
a) Subtropical desert
b) Temperate grassland
c) Boreal forest
d) Arctic tundra
3) What is the predominant type of vegetation in a tropical wet forest?
a) Shrubs and bunchgrasses
b) Herbs, grasses, and vines
c) Broad-leaved deciduous trees

4) The littoral zone of a lake is most similar to which of the following environments?
a) Oceanic zone
b) Intertidal zone
c) Neritic zone
d) Marsh
5) Typically, where are oxygen levels highest and nutrient levels lowest in a stream?
a) Near its source
b) Near its mouth, or end
c) Where it flows through a swamp or marsh
d) Where it forms an estuary
6) Why are certain exotic species considered invasive?
a) They are found in areas where they are not native
b) They were introduced by humans-often accidentally
c) They spread aggressively and displace native species
d) They benefit from increased grazing and wildfires
e)
7) Naturalists
a) Use observation as a technique to describe natural phenomena – long term field studies
b) Use the hypothetico-deductive process and manipulate aspects of the environment
c) Use computer simulations to determine the outcome of environmental perturbations

10) Why is the North American Jet Stream so squiggly?
a) The Rocky Mountains deflect it to the south
b) The Appalachian Mountains deflect it to the north
c) The Earth’s rotation causes fluctuations
d) The nature of a Jet Stream requires it to follow the curves of the coastline

e) More than one of the above
14) Why are tornadoes common in the US?
a) Warm moist air from the south meets cool dry air from the north and they mix creating
vortexes
b) Cool moist air from the south meets warm dry air from the north and they mix creating
vortexes
c) The jet stream creates turbulence through its fluctuations causing vortexes
d) Warm dry air from the south meets cool moist air from the north and they mix creating
vortexes
Closer: draw a globe and draw the major trends in climate based on latitude. Also draw in the
Hadley Cells (little circles of wind either side of the equator) and explain why these create
tropical forests and deserts at the respective latitudes that they do
