Carbon dioxide (CO2) is the primary greenhouse gas in the Earth's atmosphere, contributing significantly to the greenhouse effect and global warming.

Convection is the process by which heat is transferred through the movement of fluids, such as air or water. It occurs when a fluid is heated, causing it to expand and become less dense, and thus rise. This rising fluid carries heat with it, transferring it to cooler regions.

Updraft refers to the upward movement of air in the atmosphere. It is often associated with convection and can occur due to various factors, such as heating from the Earth's surface or the presence of low pressure.

Condensation is the process by which water vapor in the air condenses into liquid water. It occurs when the air temperature drops below the dew point, causing the water vapor to condense into tiny water droplets, forming clouds or fog.

Conduction is the transfer of heat through direct contact between two objects. It occurs when the atoms or molecules of one object collide with those of another object, transferring thermal energy between them.

Radiation is the transfer of heat through electromagnetic waves. It occurs when an object emits electromagnetic radiation, such as infrared radiation, which can be absorbed by other objects, transferring thermal energy.

The boiling point is the temperature at which a liquid turns into a gas. It is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid.

The condensation point is the temperature at which a gas turns into a liquid. It is the temperature at which the vapor pressure of the gas equals the pressure surrounding the gas.

Sublimation is the process by which a solid turns into a gas without first becoming a liquid. It occurs when the solid's molecules gain enough energy to break free from the intermolecular forces holding them in place.

Deposition is the process by which a gas turns into a solid without first becoming a liquid. It occurs when the gas molecules lose enough energy to condense into a solid state.

Deposition is the process by which water vapor in the air changes directly into ice crystals without first becoming a liquid. It occurs when the water vapor molecules lose enough energy to condense directly into a solid state.

Melting is the process by which ice crystals in the air melt and turn into liquid water. It occurs when the ice crystals absorb enough energy to break the intermolecular bonds holding them in a solid state.

Freezing is the process by which liquid water in the air freezes and turns into ice crystals. It occurs when the liquid water molecules lose enough energy to form intermolecular bonds and transition into a solid state.

Condensation is the process by which water vapor in the air changes directly into liquid water without first becoming a solid. It occurs when the water vapor molecules lose enough energy to condense into a liquid state.

Evaporation is the process by which liquid water in the air evaporates and turns into water vapor. It occurs when the liquid water molecules gain enough energy to break free from the intermolecular forces holding them in a liquid state.
