Question

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.

Answer 1

The correct answer is D) There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen.

Life on Earth could be affected if the atmosphere did NOT contain greenhouse gases in the following way: "There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen."

Scientists agree that this is basically the importance of greenhouse gases on the atmosphere of planet earth. Without these gases, the surface of the earth would have an average temperature of minus 18 centigrades. Many life forms as we know them could not survive under this hairs climate condition. Furthermore, most of the surface of the earth would be covered on ice.
