question 44
greenhouse gases warm the planet by
absorbing and reemitting infrared radiation.
magnifying the energy of solar radiation.
producing and emitting infrared radiation.
absorbing and dispersing solar radiation.

Explanation:

Greenhouse gases (like carbon dioxide) have the property of absorbing infrared radiation emitted by the Earth's surface. After absorption, they re - emit this infrared radiation in all directions, including back towards the Earth. This process effectively traps heat in the Earth's atmosphere, similar to how a greenhouse traps heat. Solar radiation is mainly in the visible and ultraviolet range (with some near - infrared). Greenhouse gases do not magnify solar radiation energy. They do not produce infrared radiation (they just absorb and re - emit the existing infrared from the Earth's surface). Also, they do not disperse solar radiation in a way that warms the planet; their key role is in the infrared (terrestrial radiation) trapping mechanism.

Answer:

absorbing and reemitting infrared radiation.
