TermDefinition
Atmosphere A mixture of gases that surrounds a planet or moon.
Hydrosphere The portion of the earth that is water.
Biosphere The part of earth where life exists includes all of the living organisms on earth
Cryosphere Is the frozen water part of the Earth system.
Second law of thermodynamics states that when energy transfer takes place matter becomes less organized with time.
Convection The movement of matter due to differences in density that are caused by temperature variations can result in the transfer of energy as heat.
Closed System A system in which both energy and matter are exchange with the surrounding
First law of thermodynamics Is transferred between system but it cannot be created or destroyed
System A set of particles or interacting components considered to be a distinct physical entity for the purpose of study .
Geosphere The mostly solid,rocky part of the earth; extends from the center of the core to the surface of the crust
Matter Anything that has mass and takes up space
Energy Is a defined as the ability to do work
open system A system in which energy, but no matt
Nitrogen cycle the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
Nitrogen fixation The process of changing free nitrogen gas into a usable form
Carbon Cycle An essential substance in the fuels used for life processes.
Carbonate forms from shells and bones of once-living organisms
Photosynthesis Plants capture solar energy by a chemical process
Cellular Respiration Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
Phosphorus cycle Part of some molecules that organisms need to build cells.
Water cycle The continuous movement of water between the atmosphere,the land,and the oceans.
Condensation The change from a gas to a liquid
Precipitation Any form of water that falls from clouds and reaches Earth's surface.
Evaporation Liquid to gas
Ecology The study of the complex relationship between living things and their nonliving or abiotic environment
Abiotic Non- living
Biotic Living
Ecosystem A community of organisms and their abiotic environment
Producer Organisms that make their own food
Consumer Organisms that get their energy by eating producers
Decomposer These consumers get energy by breaking down dead organisms
Carrying Capacity The largest population that an environment can support at any given time.
Homeostasis Cells and systems maintain a constant internal balance
Food Chain The sequence in which organisms consume other organisms con be represented.
Food Web A diagram that shows the feeding relationship among organisms in an ecosystem.
Energy Pyramid A diagram that shows the amount of energy that moves from one feeding level to another in a food web
Uncertainty doubt, the state of being unsure
Variation Any difference between individuals of the same species.
Correlation A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other.
Causal involving a cause
Erosion Processes by which rock, sand, and soil are broken down and carried away (i.e. weathering, glaciation)
Coevolution Process by which two species evolve in response to changes in each other
Viscosity A liquid's resistance to flowing
Biogeology Geographic distribution of species
Surface Tension A measure of how difficult it is to stretch or break the surface of a liquid
Density Mass / Volume
Polarity A lack of electrical symmetry in a molecule. Charge differences on opposite ends of a structure.
Sublimation Solid to gas
Vaporization Liquid to gas
Specific Heat The amount of energy required to raise the temperature of 1 gram of a substance by 1 degree celcius
Run Off Water that flows over the ground surface rather than soaking into the ground.
Ground Water underground water that is held in the soil and in pervious rocks
The total loss of water from an area, which equals the sum of the water lost by evaporation from the soil and other surfaces and the water lost by transpiration from organisms .

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
