Climate - daily conditions; Weather - seasonal conditions
Climate influences daily activities; weather seasonal
Weather - daily forecast; Climate - average over many years
Climate constantly changes; weather changes slowly over time
9
How could an increase in average global temperature influence Earth?
by decreasing periods of drought in water systems
by increasing formation of sea ice in polar regions
by decreasing erosion in coastal ecosystems
by increasing flooding due to rising sea levels
10
How could thermal pollution (heated water dumped into lakes & rivers) affect aquatic life?
increasing dissolved oxygen in the environment
increasing life expectancy of animals in aquatic environment
reducing decomposition rate of organisms
reducing number of aquatic species in the environment
11

it can improve the natural habitat of plants & animals
it can decrease the accumulation of sediment in the water
it can create a storage place for water
it is an inexpensive process
12
Which describes an abiotic factor that could impact diversity of an ecosystem?
competition for food between members of same species
increased acid rain that changes pH of soil
An increase in prey which affects number of predators
an invasive species that changes available resources
13
How could the exponential growth of human population impact regions throughout world?
decrease the demand for land in the regions
decrease the amount of pollution in regions
increase the biodiversity of the regions
increase the demand for food in the regions
14
