To happen, repeat, over and over (verb); A series of events that happen over and over again.

a form of carbon in the atmosphere that is a pollutant when there is too much of it

the MOST important building block for life; part of making (producing) glucose in cells

cycle where plants and animals die depositing carbon in the ground; how carbon moves into and out of the lithosphere; the big difference is long term carbon cycle has rocks

C = glucose in plants; CO2 in air, hydrocarbons in coal (rocks and soil); blue carbon in the oceans

Plants convert carbon in the air to organic matter(photosynthesis and respiration); how carbon move through the surface reservoirs

Plants use the sun's energy to convert water and carbon dioxide into sugars

Combining or bringing together two or more parts, things, or elements to produce something new.

the process of breaking down dead plants and animals (and other materials) into their simpler elements; rot and decay

to break down or apart into smaller or more simple pieces; "decay" suggests that something or someone is not able to function or work at its best level (Implies the deterioration from "sound"--physically and mentally healthy--condition) An apple can _______ when it rots, but an isotope can also _________.

extremely large, big, or long; for example, ________ periods of time.

Over millions of years, layers of sediments (small pieces of rock, plants, and animals) build up on one another. Pressure and heat from inside Earth's crust turn these decayed bits into carbon-based _________ ________ that are burned for energy.

-During Paleozoic

-Carbon" refers to rich coal deposits created by the swampy environment, plants growing in wetlands

-350 million years ago to 290 million years ago, before dinosaurs,

-main fossil fuels laid down in this era

Choose all the common forms of fossil fuels.

-decomposition that occurs without using, or in the absence of, oxygen

-occurs with little or no air in deep lakes, swamps

-produces fossil fuels

Carbon stored in coastal and ocean ecosystems as plants and sediment organic matter

Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere that trap heat near the surface (which are involved in the greenhouse effect.)

warming that results when solar radiation is trapped by the atmosphere

A rapid reaction between oxygen and fuel that results in fire

When we burn fossil fuels such as gasoline for our cars, we take carbon out of Earth's stored solid forms and release carbon dioxide and water vapor into the atmosphere.

Which sphere has the largest store of carbon on Earth?

the exchange of matter through the biosphere and between ecosystems

Include the Carbon cycle, the Nitrogen cycle, and the Phosphorus cycle : required by plants and animals for energy, growth, development, repair or maintenance

breathing

Manufactured by plants during photosynthesis; also the form of sugar that circulates in the blood and provides the major source of energy for body tissues. When its level is low, we feel hunger.
