The troposphere is the layer of atmosphere that contain four major greenhouse gases and therefore, is the site for the greenhouse effect. The greenhouse gases present in the lower troposphere are water vapor, carbon dioxide, methane, and nitrous oxide.
These greenhouse gases trap the radiations reflected back by earth's surface during the night. These trapped radiations serve to increase the earth's atmosphere.
This would happen because we have devices such as seismographs to record the motion of the ground during an earthquake. Without that, we wouldn't know how big the earthquake is and how to prepare for survival.
