Carbon Cycle
100
What is an open system?
Matter AND energy can enter and leave.
100
What is the hydrosphere?
Water on Earth in all phases.
100
What is evaporation?
Liquid (water) changes to gas (water vapor).
100
What are the characteristics of metals?
High shine, good conductor, malleable, and easily loses electrons.
100
What is photosynthesis?
Plants absorb sunlight and CO2 from the atmosphere to make sugars.
200
What is a closed system?
Matter doesn't enter or leave. Only some energy can enter and leave.
200
What is the geosphere?
Any of the materials that make up Earth's surface interior and ocean basins.
200
What is condensation?
Process of turning gas into a liquid (ex. clouds).
200
What are the characteristics of non-metals?
Dull, poor conductor, brittle, and tend to gain electrons.
200
What is decomposition?
Decay of plants and animals, uses oxygen and releases CO2 into the atmosphere as well as carbon into the ground.
300
What is a positive feedback loop?
Chain reactions that moves part of the system towards extremes.
300
What is the atmosphere?
A blanket of gases that surround the entire Earth extending to the edge of space.
300
What is precipitation?
Process of water falling to the ground (rain, snow, hail).
300
What are the characteristics of metalloids?
Shiny or dull, solids, and can conduct some heat but not as well as metals.
300
What is combustion?
Burning of Fossil fuels (ex. oil and coal).
400
What is a negative feedback loop?
Chain reaction that moves part of the system towards being stable.
400
What is the biosphere?
All living things.
400
What is infiltration?
Process of water moving from the surface into the ground.
400
What are characteristics of noble gases?
Full outer ring, low reactivity, and doesn't want to gain or lose electrons.
400
What is respiration?
Release of CO2 through "breathing" by plants, animals and most bacteria.
500
Earth is an example of what system?
Closed system.
500
Bacteria is an example of what sphere?
Biosphere.
500
What is transpiration?
Process of water found in trees changing from liquid to a gas.
500
What category shares properties of both metals and non-metals?
Metalloids.
500
What is consumption (food chain)?
Humans and animals get their carbon through eating plants.
