A Simple Explanation A problem to stay As more heat grets trapped by the sun the Earth starts to heat. The consequences of the greenhouse effect: from desertification to floods. Without the greenhouse effect, Earth's temperature would be below freezing. Identified by scientists as far back as 18 96, the greenhouse effect is the natural warming of the earth that results when gases in the atmosphere trap heat from. The phenomenon, called the 'runaway greenhouse' effect, occurs when a planet absorbs more energy from the sun than it can radiate back to space. Causes and examples. The primary greenhouse gases in Earth's atmosphere are water vapor (H 2 O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and ozone (O 3).Without greenhouse gases, the average temperature of Earth's surface would be about 18 C (0 . Each point: 1 Mark. When sunlight heats Earth's surface, some of the heat radiates back into the atmosphere. A greenhouse gas (GHG or GhG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. This makes the Earth hotter than it would be without greenhouse gases.This is called the "greenhouse effect".Most greenhouse gases are natural - water vapor is the most common, and causes most of the greenhouse effect on Earth. These heat-trapping pollutantsspecifically carbon dioxide, methane, nitrous oxide, water vapor, and synthetic fluorinated gasesare known as greenhouse gases, and their impact is called the. The greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases. Collins COBUILD Advanced Learner's Dictionary.
