Terms in this set (22)
why is it better for the environment if new construction takes place on already developed land versus humans developing on land that is considered a natural habitat?
won't destroy more/another habitat
non-renewable energy sources
fossil fuels, coal, natural gas
renewable energy sources
water, wind, solar
why is our atmosphere considered less polluted than 50 years ago?
factories require cleaner energy
why is raising cattle and growing pollution adding to air pollution?
what is biodiversity?
the variety of life in the world or in a particular habitat or ecosystem.
what is the leading cause of loss of biodiversity?
what is succession?
the gradual process by which ecosystems change and develop over time
disruptions that lead to primary succession
volcano eruptions, retreating glaciers
disruptions that lead to secondary succession
forest fires, hurricanes
occurs on barren land, no soil
occurs with a layer of soil
how does the greenhouse effect work?
greenhouse gases transmit visible light, allowing it to heat the surface, but then absorb infrared light from Earth, trapping the heat near the surface.
why is the greenhouse effect important to life?
keeps the earth warm enough to sustain life
how are people adding to CO2 in the atmosphere on a daily basis?
deforestation, fossil fuel emissions, pollution
why are global temperatures increasing?
increase in CO2/greenhouse gas emissions
why will global temperatures continue?
greenhouse gasses linger in the atmosphere so they attempts to stop non-renewable energy use will only have an effect in the long run
measures how many different species are in an ecosystem
measures the number of each species compared to the number of every other species
why is biodiversity important to both natural systems and to humans?
overall healthier planet, medicinal purposes
what type of growth has the human population experienced over the last 500 years?
what is a major cause of the increased extinctions in the last 100 years?
