How would life on Earth be affected if the atmosphere did NOT contain greenhouse gases? A. There would likely be a few less organisms on Earth because the lack of greenhouse gases would make Earth a little cooler. B. There would likely not be life on Earth because Earth's surface would be much hotter without the Sun's rays being blocked. C. There would likely be more diverse life on Earth because the lack of greenhouse gases would make Earth just a little warmer. D. There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen.
D. There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen. Without greenhouse gases, such as water vapor, carbon dioxide, and methane, to trap heat in the atmosphere, Earth's temperature would drop significantly, leading to freezing temperatures and ice-covered oceans. This extreme cold would not be conducive to supporting life as we know it.
