What's the greenhouse effect

The greenhouse effect is just a bunch of gases that allow direct sunlight to reach Earth's surface unimpeded. So the greenhouse is nothing but he "heating" of Earth. The three most common greenhouses gases are nitrogen which is the most aboundant, oxygen which is the second most, and argon which is the third most abundant greenhous gas. Greenhouse gases are produced when we burn forest land and mining or burning coal. The greenhouse effect has an impact on our lives when it is similar to global warming and the negative results to follow. Other negative results are sea levels rising, severe floods and droughts, and Earth's precipitation
