Chemistry of Materials
Name the three states of matter
solid, liquid, gas
What is erosion
the breaking down of sediment and moving of it
What is the instrument that measures wind speed?
anemometer
Name 2 renewable resources
water, wind, sunlight, plants,
What is a producer?
Something that makes its own food
What is an atom
the building blocks of life
Name the steps in the water cycle
precipitation, evaporation, condensation,
Wind always flows from?
High pressure to low pressure
Name 2 nonrenewable resources
rocks, dirt, soil, metals, minerals,
rabbit, grasshopper, cow, mouse, vole, birds, deer, elk,
Name a chemical property of a substance
reaction with acid
a map that shows the height changes of the land
What is the difference between weather and climate
climate is the long term average weather of an area. Weather is the specific, moment to moment state of the atmosphere.
What happens when we use too much of a natural resource
How do plants make their own food?
through photosynthesis
How many atoms does an element contain
just one type
Which liquid dissolves more substances than any other?
water
Why is earth's temperature rising?
the burning of fossil fuels is trapping gasses in the atmosphere creating a greenhouse effect that traps heat instead of letting it reflect back into space.
Explain the difference between renewable and nonrenewable resources
renewable resources can be replenished in our lifetime. nonrenewable resources cannot be replaced in a short amount of time.
What is a data transect?
An area that is roped or taped off which ecologist study instead of a whole area
Explain each of the three states of matter kinetic energy
gas- lots of energy, moving really fast, boucning, hardly interacting
liquid- some interaction, flowy, medium energy
solid- vibrating, very close, not tons of energy
Explain how a dead zone is formed
explain how ocean currents work.
cold, salty water is more dense so it sinks at the poles. The water then travels towards the equator. It looses salt and gains temperature so it starts rising. water, less salty water is less dense so it rises. It travels towards the poles.
What is a natural resource
Something found naturally on earth that humans use
Describe what effect an invasive species can have on a ecosystem
negative impact. disrupt the food chain, use too many resources, hurt biodiversity and crowd out native plants.
