Environmental ScienceMidterm Review
• Natural resources• Food, water, metals, minerals, coal, oil, natural
gas
• Ecology• The study of the interaction between all life
forms and the non-living components of Earth
• Industrial revolution• The invention of machines and energy to do
man’s work.• Added pollution, increased populations,
climate change•
• Overconsumption• Rich countries over consume natural resources
at a rate where they cannot be replaced•
• Pollution• Air, water, soil•
• Over population• Too many people; not enough resources for all•
• Hypothesis• A prediction to solve a problem
• Scientific theory• A hypothesis proved true many many times
• Biosphere• All air, water, and land on Earth
• Atmosphere• The air above earth and before outer space
• Hydrosphere• The water – fresh and salt on Earth•
• Lithosphere• Outer solid part of the earth• Site where plate tectonics occurs
• Earth Crust• What happens to temperature and pressure as
you move towards the center of the Earth?• Pressure and heat Increase as you move
towards core
• Outer core• Molten Lava – liquid hot•
• Inner core• Solid ball iron and nickel – magnetic; gravity•
• Pangaea• All continents form one super continent
Weather Map Symbols (H, L)
• Cold front• Cold wind that replaces warm wind. • Cold and dry•
• Interaction of CFC and Ozone• CFC – come from refrigerators and aerosol
spray cans• Eats away at Ozone
• Weathering and Erosion• Break down of rocks; land, mountains due to
wind and weather•
• Ecosystem• Geographic area- all living and non-living
components
• Abiotic• Not living – air, water, soil, sunlight, climate
• Biotic• Living – all life
• Energy in an ecosystem• Sun – moves through the food chain• Much is lost
• Habitat• Place – environment an organism lives in
Niche• Role or job in an ecosystem• House fly: Decompose organic matter• Honey bee: Pollinate flowering plants• Worms are decomposers, therefore his niche would be to break down
decaying carcasses and leaves.
• Wolves in Alaska are to control the caribou population, but the governor up there thinks that's her job
• Urban striped skunk. - Its niche is eating catfood, garbage, small rodents, bird eggs, anything else, denning under porches, spraying at dogs and children who chase them, dying or rabies or other diseases, getting hit by cars, and eaten by great horned owls.
• Producer• Make food from sunlight
• Consumer• Eat plants or animals•
• Secondary consumer• Eat primary consumers
• Decomposer• Fungi, bacteria, or scavengers – eat dead
organisms- break them down
• Population• Number of one type of organism in a very
specific area of land•
• Evolution• The change of life forms over time
• Natural selection• Nature selects the
organisms with the best traits to survive and pass their genes
• Adaptation• A beneficial trait that helps an organism
survive
• Camouflage• Blend in with environment
• Warning colors• Bright colors indicate they are poisonous to
eat.
• Mimicry• Copy animals with warning colors, but are not
poisonous
Honeybee harmless fly
• Succession• Forest• Gets destroyed – describe how new forest
forms • Grasses – shrubs - trees
• Biome• Places on Earth – specific geographic location,
climate, plants, and animals
• Tropical Rainforest• Hot, rainy• species of animals
with specialized ways of surviving in order to avoid competition
• Deciduous forest• Trees grow lush green leaves in the spring, but
lose their leaves in late summer.
• Temperate Rain forest• low rainfall in summer but abundant snow in
winter.
• Tundra• tundra, then grasslands, then tropical rain
forests
• Equator• Center of Earth that gets most sun….hot
