The correct answer is - ozone.
The ozone is essentially three molecules of oxygen, or O³. This gas is crucial for the life on the Earth because it is the one that manages to filter out big portion of the UV radiation from the Sun which is extremely harmful if its too strong, as it will contribute to the dying out of pretty much every living organism.
While the ozone layer in the stratosphere is very useful, the ozone in the lower parts of the troposphere is actually considered as pollutant. The reason why it is considered as pollutant is because it is very harmful if inhaled, and it also heavily damages the plants.
Hey there! I'm happy to help!
The countries in the Middle East that export petroleum are Saudi Arabia, Iran, Iraq, United Arab Emirates, Kuwait, Qatar, Oman, and I think there are a few more but those are the main ones. Lots of Middle Eastern countries export it but these are the main ones. Places like Saudi Arabia and Iran have lots of oil fields available, so they would naturally export lots of petroleum.
Have a wonderful day! :D
According to one hypothesis, life on earth emerged from (bluegreen algae/ amino acids/ molten metals/ crustal rocks) in the presence of large amounts of gasses seeping from deep ocean vents. ANother process called primordial soup suggests that the formation of life was due to the effects of (lightning/sunlight/gravity/meteorites) in earths atmosphere.
I believe the answer is <span>Fossil fuel plants are built closer to the oceans than geothermal plants.</span>
