How do bodies of water affect regional and local climate? - CORRECT ANSWERS Ocean
currents influence climate of nearby terrestrial environments by heating or cooling overlying air
masses that pass across land.
How do mountains affect regional and local climate? - CORRECT ANSWERS Mountains
influence airflow over land, affecting surrounding areas. Warm air cools as it rises up a
mountain and releases moisture on the windward side; cool and dry air absorbs moisture from
land as it descends, creating a rain shadow on the leeward side.
How is a rain shadow created? - CORRECT ANSWERS 1. Cool air flows, absorbing
moisture from
2. It precipitates as it descends
3. It creates a rain shadow on the leeward side.
How does the burning of fossil fuels contribute to the net increase in atmospheric carbon? -
CORRECT ANSWERS The burning of fossil fuels and deforestation increased the
concentration of greenhouse gases in the atmosphere, so wind and precipitation patterns are
shifting, and global temperature and the frequency of extreme weather events have increased.
How can you predict the effects of future global climate change? - CORRECT ANSWERS
- Study how species responded to changes in the past.
- Geographic ranges of many species have shifted; species that have difficulty dispersing or a
shortage of suitable habitat may have reduced ranges or could become extinct.
What is California's biome? - CORRECT ANSWERS Chaparral: occurs in midlatitude
coastal regions on several continents; precipitation highly seasonal with rainy winters and dry
summers (very hot 30-40º), cool remainder of year (10-12º)

Dominated by shrubs, small trees, grasses, and herbs. Many plants adapted to fire and
droughts.
Animals: amphibians, birds and other reptiles, insects, browsing mammals, and a diversity of
small mammals.
Humans: reduced chaparral areas through agriculture and urbanization.
What is the major factor determining the location of terrestrial biomes? - CORRECT
ANSWERS Climate. Because it strongly influences the distribution of plants. It's affected by
mean temperature and precipitation, and pattern of precipitation through year.
What are the terrestrial biomes' general features? - CORRECT ANSWERS - Named for
major physical or climatic factors and predominant vegetation.
- Usually grade into each other.
- Vertical layering
- Species composition of each kind of biome varies from one location to another.
Give me aspects of Taiga, - CORRECT ANSWERS Northern coniferous forest
- Spans northern North America and Eurasia, being the largest terrestrial biome on earth.
- Precipitation varies; some forests have periodic drought and others, especially near coasts.
- Cold winters and variable summers. (e.g. Siberia -50 to 20ºC)
- Evergreen conifers such as pine, spruce, fir, and hemlock
- Animals are migratory and resident birds, large mammals (moose, brown bears, and Siberian
tigers)
- Humans: rapid rate of logging of old-growth stands (may soon disappear)

Give me aspects of aquatic biomes - CORRECT ANSWERS - It's characterized by their
physical and chemical environment, geologic features, photosynthetic organisms, and
hetereotrophs
Differentiate marine from freshwater biomes. - CORRECT ANSWERS Marine biomes:
average salt concentration 3% and oceans make up the largest marine biome, covering about
75% of Earth.
Freshwater biomes: salt concentration of <0.1% and they surrounding terrestrial biome,
patterns and speed of water flow, and climate all influence their characteristics.
How is the aquatic biome zoned? - CORRECT ANSWERS By light penetration,
temperature, and depth.
What is the difference between thermocline and turnover zones in aquatic biomes? -
CORRECT ANSWERS Thermocline: temperature boundary in oceans and most lakes
that separates warm upper layer from cold deeper water
Turnover: mixing of oxygenated water from the surface with nutrient-rich water from the
bottom. Many lakes undergo this semiannually
Give me examples of aquatic biomes. - CORRECT ANSWERS Lakes, wetlands,
streams/rivers, estuaries, intertidal zones, oceanic pelagic zones, coral reefs, and marine
benthic zones.
What are the factors limiting geographic distribution? - CORRECT ANSWERS
Interactions between organisms and the environment limit distribution of species
