Pathways

1 / 35

36 Terms

1

Pathways

________: Processes that move the elements between the reservoirs.

New cards
2

Deposition

________: The laying down of sediment carried by wind, flowing water, the sea or ice.

New cards
3

Combustion

________: Occurs when any organic material is reacted (burned) in the presence of oxygen to give off the products of carbon dioxide, water, and energy.

New cards
4

Biomass

________: Renewable energy that comes from organic matter /organisms.

New cards
5

Fewer trees plants

________ mean less photosynthesis and glucose.

New cards
6

Fossil Fuel Formation

________: Dead organic matter builds up underground faster than it can be anaerobically decomposed, and sediment pressurizes it.

New cards
7

Photosynthesis

________: The process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

New cards
8

Cellular Respiration

________: The process of breakdown of food in cells and organisms with the release of energy.

New cards
9

Biosphere

________: The part of Earths surface where life exists.

New cards
10

Reservoirs

________: Places where elements are stored for part of the time.

New cards
11

Diffusion

________: Molecules moving from an area of higher concentration to one of lower concentration.

New cards
12

Ocean Biosphere

________: The part of the Ocean where life exists.

New cards
13

Shell Formation

________: To build shells, marine life extracts calcium and carbonate ions from ocean water, combining them to make shells.

New cards
14

Biogeochemical Cycles

Cycles of elements as they move through living and nonliving factors

New cards
15

Reservoirs

Places where elements are stored for part of the time

New cards
16

Pathways

Processes that move the elements between the reservoirs

New cards
17

Biomass

Renewable energy that comes from organic matter/organisms

New cards
18

Organic Compounds

Compounds that have carbon-carbon or carbon-hydrogen bonds

New cards
19

Photosynthesis

The process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar

New cards
20

Cellular Respiration

The process of breakdown of food in cells and organisms with the release of energy

New cards
21

Combustion

Occurs when any organic material is reacted (burned) in the presence of oxygen to give off the products of carbon dioxide, water, and energy

New cards
22

Anaerobic Decomposition

Decomposition without the use of oxygen

New cards
23

Fossil Fuel Formation

Dead organic matter builds up underground faster than it can be anaerobically decomposed, and sediment pressurizes it

New cards
24

Diffusion

Molecules moving from an area of higher concentration to one of lower concentration

New cards
25

Shell Formation

To build shells, marine life extracts calcium and carbonate ions from ocean water, combining them to make shells

New cards
26

Deposition

The laying down of sediment carried by wind, flowing water, the sea or ice

New cards
27

Atmosphere

The layers of gases surrounding a planet or other celestial body

New cards
28

Contains Carbon Dioxide (CO2) and Methane (CH4

converts to CO2 and H2O through exposure to Ozone)

New cards
29

Biosphere

The part of Earths surface where life exists

New cards
30

Contains consumers, biomass, and organic molecules (ex

Glucose [C6H12O6])

New cards
31

Lithosphere

The solid, outer part of Earth, including the brittle upper portion of the mantle and the crust

New cards
32

Hydrosphere

All the waters on the Earths surface

New cards
33

Ocean Biosphere

The part of the Ocean where life exists

New cards
34

Contains organisms, biomass, organic molecules (ex

Glucose [C6H12O6]), and Calcium Carbonate

New cards
35

More carbon in the air = more heat

global warming

New cards
36

Traps a lot of heat

global warming
