Matter | It's everything that has mass and occupies space in the universe. |
Energy | It exist in many forms, such as heat, light, chemical energy, and electrical energy. It's the ability to bring about change or to do work. Thermodynamics is the study of energy |
System | It's a set of connected things or parts forming a complex whole. |
Open system | It's a material system in which mass or energy can be lost to or gained from the environment. |
Closed system | It's a region that is isolated from its surroundings by a boundary that admits no transfer of matter, only energy across it. |
Atmosphere | Air (oxygen, nitrogen, water vapor, ozone, wind) |
Hydrosphere | Water (Oceans, lakes, rivers, groundwater, glaciers, polar ice caps, rain, snow) |
Geosphere | Land. Earth's mantle, core, and crust: continents, ocean floor, mountains, rocks, sand, metals, dust, asphalt, bricks. |
Biosphere | Life (plants, humans, insects, microbes, animals) |
Cryosphere | Frozen/solid water (glaciers, ice caps, ice sheets, Greenland, Antarctica, North Pole) |
First law of thermodynamics | It states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another. |
Second law of thermodynamics | It states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." this is also commonly referred to as entropy. |
Convection | When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. The fluid above a hot surface expands, becomes less dense, and rises. |
Nitrogen cycle | N2 gas in the atmosphere is not to be used by living organisms. Bacteria, industrial process, and lighting can fix it. The usable form of N2 is Nitrate. |
Nitrogen fixation | Nitrogen can only be fixed in 3 ways: bacteria, industrial process, and lightning. |
Carbon Cycle | It's a biogeochemical cycle involving carbon (C). It's the organic circulation of carbon from the atmosphere into organisms and back again |
Carbonate | CO3 -2. |
Photosynthesis | Plants use the sun's energy to convert water and carbon dioxide into sugars and exhale oxygen. CO2+H2O+light energy= C6 H12 O6 (glucose/sugar) O2 (oxygen) |
Cellular Respiration | The process by which cells use oxygen to produce energy from food |
Phosphorus cycle | It's atoms go from rocks to water and plant roots, then ot animals and back to rocks/soil. It rarely goes to the atmosphere since it's rarely a gas. |
Water cycle | Continuous circulation of water through the hydrosphere. It first evaporates from forms of water, then it condensates into clouds and precipitates as rain and back into forms of water (ocean, river, lake, etc). |
Condensation | Water vapor moving together to form a cloud |
Precipitation | Rain/snow that falls from the cloud |
Evaporation | Water moving from a pond, river, ocean, etc., to air. |

Energy pyramid | A diagram that shows the energy flow of a community in different levels, which represent different organisms groups that might make a food chain |
Greenhouse effect | Process by which radiation from the earth's atmosphere warms the planet's surface to a temperature above what it should be without its atmosphere. |
Global warming | observed century-scale rise in the average temperature of the Earth's climate system, and its related effects. Multiple lines of scientific evidence show that the climate system is warming |
Ozone | a colorless unstable toxic gas with a pungent odor and powerful oxidizing properties, formed from oxygen by electrical discharges or ultraviolet light. It differs from normal oxygen (O2) in having three atoms in its molecule (O3). |
Weather | the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc. |
Climate | the weather conditions prevailing in an area in general or over a long period. |
Sustainability | the ability to be maintained at a certain rate or level. |
Renewable resource | Substance of economic value that can be replaced or replenished in the same or less amount of time as it takes to draw the supply down. |
Non renewable resource | Resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. |
Biodegradable | Capable of being decomposed by bacteria or other living organisms. |
Non-biodegradable | A substance or chemical that is non-biodegradable cannot be changed to a harmless natural state by the action of bacteria, and may therefore damage the environment. |
Troposphere | The lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere. |
Mesosphere | Region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude. |
Stratosphere | The layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere). |
Thermosphere | Region of the atmosphere above the mesosphere & below the height at which the atmosphere ceases to have properties of a continuous medium. It's characterized throughout by an increase in temperature with height. |
Albedo | Measure of the diffuse reflection of solar radiation out of the total solar radiation received by an astronomical body. It is dimensionless and measured on a scale from 0 to 1. |
