Carbon Cycle

Question 1

Carbon

Answer 1

is the chemical element with symbol the C and is an essential component in chemical reactions that sustain life, such as cellular respiration. It is part of CO2 (carbon dioxide) which is stored in the atmosphere, and all living things contain billions of carbon atoms in their cells. It can be stored in many different places such as plants, the ocean, coal deposits, etc.

Question 2

Atmosphere

Answer 2

the layers of gases around the Earth. We can measure the composition of the atmosphere from the air bubbles trapped in the ice (co2, o2, n2 etc.) Any gases in the atmosphere that absorb heat are called GHG.

Question 3

Troposphere

Answer 3

where weather occurs. 78% nitrogen, 21% oxygen, 1% other gases

Question 4

Stratosphere

Answer 4

where airplanes travel, air is calmer here. Also where the ozone layer is located.

Question 5

Mesosphere

Answer 5

where meteors burn up

Question 6

Thermosphere

Answer 6

where the ISS is located

Question 7

Exosphere

Answer 7

where most satellites are found

Question 8

Biosphere

Answer 8

the part that layers the Earth where living things such as plants, humans, and animals are located. Plants and animals affect the amount of gas.

Question 9

Geosphere/Lithosphere

Answer 9

the part that layers the earth where rocks, non-living things are located such as rocks, minerals, soil, etc.

Question 10

Hydrosphere

Answer 10

the part that layers the earth that includes all water (solid, liquid, gas form) on Earth.

Question 11

Carbon Dioxide

Answer 11

a common, and naturally occurring gas that is represented with CO2 (two oxygen atoms and one carbon atom). Carbon dioxide is one of the biggest factors in GHE, makes up about a quarter in natural GHE, and makes up 0.0385% (385-400 PPM) of the atmosphere. CO2 is involved in cellular respiration (CO2 produced when exhaling) and photosynthesis (is used for energy for plants). The amount of CO2 are caused by the seasons.

Question 12

Natural Carbon

Answer 12

Carbon caused by natural processes such as volcanic eruptions, decomposition, cellular respiration, and forest fires.

Question 13

Cellular Respiration

Answer 13

the process in which humans and animals release carbon dioxide as a waste product and back into the atmosphere by converting carbohydrates and oxygen into carbon dioxide and water. During cellular respiration, energy is released within the cells of the organism for the purpose of growth, repair, anNd reproduction.

Question 14

Photosynthesis

Answer 14

an important process in which oxygen and carbon are cycled through ecosystems. It is a chemical reaction that converts solar energy into chemical energy, and is used by plants, plankton, algae. During photosynthesis, carbon (in the form of CO2 in the atmosphere), enters through the leaves of plants and reacts with the water when exposed to sunlight which produces energy-rich sugars (aka carbohydrates and oxygen)

Question 15

Decompositions

Answer 15

the breaking down of dead organic matter. Decomposers converts organic molecules such as cellulose back into carbon dioxide, which gets released into the atmosphere. EX of decomposers: bacteria, animals (pillbugs and worms),fungi (mushrooms).

Question 16

Sedimentation

Answer 16

the process contributes to the formation of sedimentary rock. During sedimentation, soil particles and decaying/dead matter accumulate in layers on the ground or at the bottom of the ocean/other large bodies of water. The layers get turned into rock over a long period of time.
