What is one effect of methane gas being released into Earth’s atmosphere? *
bogdanovich [222]

Answer:

An increase in the amount of greenhouse gases in the atmosphere

Liquid; gas

Lacking oxygen

To decrease the temperature in the compost pile

Explanation:

1.  Methane is one of the greenhouse gases. When these gases are released into the atmosphere, they increase the temperature of the earth surface because they trap heat within the earth. Other examples are carbon dioxide and water vapor.

2. Evaporation is a phase change from liquid to gas. During this process, heat is supplied to a liquid. When the molecules of the liquid gain enough energy, they then begin to break off into gaseous form. The reverse process of evaporation is condensation.

3.  Anaerobic is a process that lacks oxygen. Aerobic processes are carried out with the availability of oxygen.  

4. The reason why compost should be regularly mixed is to decrease the temperature in the compost pile. Portions of the compost can have a higher temperature than other parts. Therefore, mixing the compost will help to redistribute the heat in the compost.
