Answer

The greenhouse effect refers to the process by which certain gases in the Earth's atmosphere trap heat. These gases prevent the radiation of heat that is absorbed from the sun, thereby maintaining the planet's temperature at a level conducive to life. Without this effect, Earth would be significantly colder, making it inhospitable.
