Question

substances called blank are important because they act as a blanket to keep blank in our atmosphere. However , human actives can blank the concentrations of greenhouse gases in the atmosphere so much that they keep too thermal energy in the atmosphere. This causes global temperatures to blank which is a phenomenon called blank. This phenomenon is one contributing factor to changes in long term weather patterns known as blank.

Answer 1

substances called greenhouse gases are important because they act as a blanket to keep heat in our atmosphere. However, human activities can increase the concentrations of greenhouse gases in the atmosphere so much that they keep too much thermal energy in the atmosphere. This causes global temperatures to rise which is a phenomenon called global warming. This phenomenon is one contributing factor to changes in long term weather patterns known as climate change.
