A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
Chlorophyll
The movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth’s crust. EX> Phosphorus cycle,Oxygen cycle ,Carbon cycle, Nitrogen cycle
Biogeochemical cycle
The geologic time scale is the “calendar” for events in Earth history
Time scale
A simplification of a connected system where a substance (like water) is held in reservoirs and moves between reservoirs through transport processes or fluxes
Box model
The biosphere of the earth or another planet, especially when the interaction between the living and nonliving components is emphasized
ecosphere
A natural, organic material that forms in wetlands when plant matter decomposes under low oxygen conditions
Peat
General definition: a concept that describes how a change increases over time as each new amount or fact is added
Cumulative Change
A system that transfers energy, but not matter, across its boundary to the surrounding environment
Closed System
The Anthropocene Epoch is an unofficial unit of geologic time, used to describe the most recent period in Earth’s history when human activity started to have a significant impact on the planet’s climate and ecosystems
Anthropocene
The color and width of tree rings can provide snapshots of past climate conditions
Tree Rings
The electromagnetic spectrum, includes energy from long wavelengths (radio waves), through visible light, all the way to short-wavelength X-rays and gamma waves
Electromagnetic waves
Organisms, such as plants and phytoplankton, that can produce their own food through photosynthesis or chemosynthesis
Primary Producer
The rate of transfer of fluids, particles or energy per unit area across a given surface
Flux
he rate at which solar energy is captured in sugar molecules during photosynthesis
gross primary production
A hydrocarbon is an organic compound consisting of hydrogen and carbon found in crude oil, natural gas, and coal
Hydrocarbon
he total amount of water on a planet
Hydrosphere
A combustible black or brownish-black sedimentary rock with high amounts of carbon and hydrocarbons
Coal
A generic term for non-renewable energy sources such as coal, coal products, natural gas, etc.
Fossil Fuels
Involves the movement of carbon atoms over a relatively short period of time
Short term carbon cycle
A series of graphs for different plant species displayed side by side
Pollen Diagram
Realm of technology and its effect on the climate
technosphere
The theory that change in the earth’s crust during geological history have resulted from the action of continuous and uniform processes
Uniformitarianism
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water during photosynthesis, water and carbon dioxide combine to form carbohydrates and give off oxygen
Photosynthesis
The release of CO2 into the atmosphere, soil and oceans by animals as they exhale
Respiration
