Plzz why should you choose an electronic source with an author

mark me as brainliest, this question does nnot make sense.

the universe is complete credible source of our oxygen

it depends on the natural disaster. a good one you can choose are hurricanes. water vapor is the "gas" and warm fronts are the "spark". because of the global warming that humans have caused with green house gases, hurricanes have become more frequent and stronger, making them more dangerous.
