Ozone is a type of oxygen that is abundant in the stratosphere, and is a pollutant at lower altitudes.
Which of these protects Earth from harmful radiation when in the stratosphere but is a pollutant at lower altitudes?
Which of these protects the earth from harmful radiation when found in the stratosphere but is a pollutant at lower altitudes a carbon oxygen
ozone hydrogen
? The correct answer is – ozone.
What protects Earth from harmful radiation in the stratosphere?
The ozone layer
in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB.
Which part of Earth protects it from harmful radiation of outer space?
The ozone layer
acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth’s surface.
How does ozone protect us from UV B?
How does ozone protect us from UV-B?
Ozone absorbs UV-B radiation from the sun
. When an ozone molecule absorbs UV-B, it comes apart into an oxygen molecule (O
2
) and a separate oxygen atom (O). … By absorbing UV-B in the stratosphere, the ozone layer prevents harmful levels of this radiation from reaching Earth’s surface.
What protects us from solar radiation?
The Earth’s atmosphere and magnetic shield
protect us from cosmic radiation. Earth’s magnetic shield protects us from the cosmic radiation and is strongest at the equator and weakest near the poles. … Earth’s atmosphere shields us from most of the remaining radiation that travels to Earth.
Which is the coldest layer of our atmosphere?
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface,
the mesosphere
gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
What 3 types of waves can be harmful to life?
However, the Earth’s atmosphere protects us from exposure to a range of higher energy waves that can be harmful to life.
Gamma rays, x-rays, and some ultraviolet waves
are “ionizing,” meaning these waves have such a high energy that they can knock electrons out of atoms.
What is the hottest layer of the atmosphere?
The thermosphere
is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km.
What subsystem protect us from the sun harmful radiation?
Earth’s stratospheric ozone layer
is a belt of naturally occurring ozone gas that sits 10 to 30 miles above Earth and serves as a shield from the harmful ultraviolet radiation emitted by the sun.
How are we protected from the sun’s harmful radiation on Earth?
Fortunately,
the Earth’s atmosphere
protects us from most UV radiation. While we need some exposure to sunlight to help our bodies make vitamin D, too much UV is dangerous. Broad-spectrum sunscreen provides protection from the sun’s Ultraviolet (UV) radiation.
Does UV light destroy ozone?
Ozone residuals are destroyed at UV light wavelengths
ranging from 250 to 260 nm, while microorganism inactivation can be achieved at UV wavelengths ranging from 100 to 400 nm, although a wavelength of 254 nm is most effective.
How does ionosphere influence human activities?
The ionosphere also plays a role in our everyday communications and navigation systems. Radio and GPS signals travel through this layer of the atmosphere, or rely on
bouncing off the ionosphere to reach their destinations
. In both cases, changes in the ionosphere’s density and composition can disrupt these signals.
How is ozone harmful to us?
How is Ozone Harmful? … When inhaled,
ozone can damage the lungs
. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
Which human health effects increases from damage to the stratospheric ozone layer?
Ozone layer depletion causes
increased UV radiation levels
at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
How can I protect the ozone layer?
- Avoid the consumption of gases dangerous to the ozone layer, due to their content or manufacturing process. …
- Minimize the use of cars. …
- Do not use cleaning products that are harmful to the environment and to us. …
- Buy local products.
