f. Photosynthesis​

Answer 1

$\huge\fbox\red{Question}$

Define the following terms.

A. Atmosphere

B. Troposphere

C Atmospheric humidity

D. Combustion

E. Fuel

F. Photosynthesis

$\huge\fbox\blue{Answer}$

A. The atmosphere of Earth is the layer of gases, commonly known as air, retained by Earth's gravity, surrounding the planet Earth and forming its planetary atmosphere.

B. The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains 75% of the atmosphere's mass and 99% of the total mass of water vapour and aerosols.

C. Atmospheric humidity is the amount of water vapor carried in the air. It can be measured as vapor pressure, mixing ratio or specific humidity. Atmospheric water vapor is also the most important greenhouse gas in the atmosphere.

D. Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

E. A fuel is any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work. Fuels are also used in the cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy.

F. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
