2023年3月13日 · The ozone layer absorbs 97% to 99% of the sun’s incoming ultraviolet radiation (UV-B). This is fundamental to protecting life on Earth’s surface from exposure to harmful levels of this radiation, which can damage and disrupt DNA.

2023年10月19日 · The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms’ protective layers, like skin. This then may damage DNA molecules in plants and animals. There are two major types of UV light: UVB and UVA.

The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O 3 ) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

2023年1月14日 · The ozone layer is a thin sheet of gas that surrounds planet of Earth. It absorbs 98% of the harmful ultraviolet rays from the Sun

2025年2月13日 · Most importantly, it absorbs the portion of UV light called UVB UVBA band of ultraviolet radiation with wavelengths from 280-320 nanometers produced by the Sun. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects. UVB is particularly effective at damaging DNA.

2016年3月9日 · Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity of the atmosphere is progressively reduced. Consequently, the people and the environment are exposed to higher levels of UV radiation, especially UVB.

The absorption of ultraviolet radiation by ozone creates a source of heat, which actually forms the stratosphere itself (a region in which the temperature rises as one goes to higher altitudes). Ozone thus plays a key role in the temperature structure of the Earth's atmosphere.

The ozone layer acts as an invisible shield and protects us from harmful ultraviolet (UV) radiation from the sun. In particular, the ozone layer protects us from the UV radiation, known as UV-B, which causes sunburn.

2025年1月29日 · Located 15–35 km above the Earth’s surface, the ozone layer acts as a shield, protecting humans, animals and plants from harmful ultraviolet (UV) radiation from the sun, in particular UV-B. Without the ozone layer, the Earth would be a very different place: crops would fail, and humans would be blighted by everything from cataracts to skin ...

2025年2月14日 · What's the difference between the Ozone Layer and Ozone Hole? The ozone layer is a layer in Earth's atmosphere that absorbs most of the Sun's UV radiation. It contains relatively high concentrations of ozone, although it is still very small with regard to …
