Natural Cycles

Water Cycle

100

What Elements compound the water and what is the quantity of each one?

Hydrogen = 2

Oxygen = 1

200

The three most abundant elements of the universe

Hydrogen

Helium

Oxygen

300

Name of the meteorite that contains water.

Carbonaceous chondrites

400

In stages of the water cycle that a stage water at the surface turns into water vapors and in the other one the water vapor changes into very tiny particles of ice/water droplets because of low temperature.

Evaporation and condensation

500

The process where ice directly converts into water vapors without converting into liquid water.

The other stage is the process where ice directly converts into water vapors without converting into liquid water.

Sublimation

Transpiration

Carbon Cycle

100

The number and symbol on the periodic table.

C = 6

200

Process where plants use carbon dioxide from the atmosphere to produce food.

Photosynthesis

300

Organisms release carbon dioxide into the atmosphere.

Respiration

400

Carbon enters the food chain when animals eat producers and other consumers.

Carbon consumption

500

The process where fossil fuels in Factories and Automobiles release carbon into the atmosphere.

Combustion

Nitrogen Cycle

100

The number and symbol on the periodic table.

N = 7

200

What is the life molecule that contains nitrogen?

DNA / RNA

300

The process of converting atmospheric nitrogen into usable nitrogenous.

Nitrogen fixation

400

Nitrogen returns to the air as nitrates are converted to atmospheric nitrogen (N2) by bacteria.

Denitrification

500

The process where the available nitrogen can be absorbed by the plants through their root systems. Here we have nitrites and nitrates (NO2- & NO3-)

Nitrification
