Which molecule absorbs UV C radiation in the stratosphere?


Is over 95% of incoming UV B radiation is absorbed in the stratosphere?

The correct answer is – True. The stratosphere manages to absorb around 95% of the UV radiation that comes from the Sun. The stratosphere acts like a protective layer in our atmosphere for the living organisms on our planet.

Where is over 95% of incoming ultraviolet radiation absorbed a the stratosphere B the mesosphere C the troposphere d the thermosphere?

The 95% of the incoming ultraviolet radiation is absorbed in the stratosphere. So, the answer to the question above is letter A. Stratosphere is the second layer of the Earth’s atmosphere as we move upwards.

Which layer of atmosphere is responsible for the change in weather Why?


Which layer of the atmosphere is responsible for the northern lights?


Which layer of atmosphere do all the weather conditions occur?

Living at the surface of the Earth, we are usually only aware of the events happening in the lowest layer, the troposphere, where all weather occurs. The base of this layer is warmer than its top because the air is heated by the surface of the Earth, which absorbs the Sun’s energy.

What component of the atmosphere is responsible for the weather changes?

The Thermosphere 75 percent of the entire atmosphere is comprised of the troposphere, which is the lowest level of the atmosphere. It extends to a maximum height of 16 kilometers (9.9 miles) at the equator. It’s in this layer that the majority of weather is determined/occurs.

What is the most important part of the atmosphere?

Troposphere is considered as the most important layer of atmosphere. It is the lower most layer of the Atmosphere.

What is the most important component of the atmosphere?

Nitrogen and oxygen together make up 99% of the planet’s atmosphere. The rest of the gases are minor components but sometimes are very important (Figure below). Nitrogen and oxygen make up 99% of the atmosphere; carbon dioxide is a very important minor component. Humidity is the amount of water vapor in the air.

What is the most important gas in the atmosphere?


Which gas is least in atmosphere?

Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere’s mixture of gases. The atmosphere also includes water vapor.

What are 3 functions of the atmosphere?

Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation.

Which is the most abundant rare gas in the atmosphere?


Which noble gas is most abundant in the atmosphere?


Which noble gas is most abundant in atmosphere dry air?

Which one of the noble gases is the most abundant in nature?

Which noble gas is commonly found in the atmosphere?

Why is there so much argon in the atmosphere?

In earth’s atmosphere, Ar-39 is made by cosmic ray activity, primarily with Ar-40. In the subsurface environment, it is also produced through neutron-capture by K-39 or alpha emission by calcium. Argon-37 is produced from the decay of calcium-40, the result of subsurface nuclear explosions.

What is the percentage of inert gases in the atmosphere?

Changes in Composition

Composition of Earth’s Atmosphere
Nitrogen 78.1%
Oxygen 20.9%
Argon 0.9%
Carbon dioxide, Methane, Rare (inert) gases 0.1%

Is noble gas and inert gas same?

The noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.

What are the 7 layers of atmosphere?

Layers of the atmosphere

  • The Troposphere. This is the lowest part of the atmosphere – the part we live in.
  • The Stratosphere. This extends upwards from the tropopause to about 50 km.
  • The Mesosphere. The region above the stratosphere is called the mesosphere.
  • The Thermosphere and Ionosphere.
  • The Exosphere.
  • The Magnetosphere.

Why co2 is not used as an inert gas?

Nitrogen gas and carbon dioxide are referred to as inert gases because of their very low reactivity. These gases are not inert in the same way as the noble gases, which exist in their elemental form. They do behave similarly to the noble gases, however.

Can you smell carbon dioxide?

You can’t see or smell carbon monoxide gas, which makes it even more dangerous. Carbon monoxide can infiltrate your home without you ever knowing until symptoms strike. The longer and more significant a person’s exposure to carbon monoxide, the more severe the symptoms can become, ultimately leading to death.

Is nitrogen a inert gas?

Nitrogen is an inert gas that is suitable for a wide range of applications, covering various aspects of chemical manufacturing, processing, handling, and shipping. Nitrogen is not reactive and it is excellent for blanketing and is often used as purging gas.

What do we breathe out when we exhale?

When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out).

Which layer of the atmosphere is responsible for absorbing UV rays?

Stratosphere 10–31 Miles – The ozone layer lies within the stratosphere and absorbs ultraviolet radiation from the Sun. Troposphere 0–10 Miles – The troposphere is the layer of the Earth’s atmosphere where all human activity takes place.

Which atmospheric gas filters out the most ultraviolet radiation in sunlight?

ozone gases

How does the atmosphere filter out harmful rays?

Gases in Earth’s atmosphere form a protective layer Nitrogen, oxygen and ozone molecules in the upper atmosphere and stratosphere absorb ultraviolet light from the Sun, providing a shield that prevents this radiation from passing to the Earth’s surface.

What is the role of ozone layer in the atmosphere?

The stratospheric ozone layer absorbs ultraviolet (UV) radiation, preventing dangerous UV rays from hitting Earth’s surface and harming living organisms. UV radiation plays a small role in global warming because its quantity is not enough to cause the excess heat trapped in the atmosphere.

Which atmospheric layer is most important for human beings?


What gases are important to sustain life?

Carbon dioxide and oxygen are the gases in the atmosphere that are needed for life. Plants need carbon dioxide for photosynthesis. They use sunlight to change carbon dioxide and water into food. The process releases oxygen.

How important are gases in our daily life?

Atmospheric Gases are Indispensable for Life on EarthEdit Carbon dioxide (CO2) and oxygen (O2) are the most important gases for living organisms. CO2 is vital for use by plants in photosynthesis, in which plants use CO2 and water to convert the Sun’s energy into food energy.

Is smoke a gas Yes or no?

Smoke is a mixture of gas (usually air) and solid and/or liquid phases. The fraction of the condensed particles determines the opacity of the smoke. It is same as air dust, but it is a product of burning while dust is a product of mechanical process. Aerosols are the same but they are finely dispersed liquids in air.

What are the 5 types of gases?

Gases expand to fill the space they are given.

  • Air.
  • Helium.
  • Nitrogen.
  • Freon.
  • Carbon dioxide.
  • Water vapor.
  • Hydrogen.
  • Natural gas.

Is sledge immune to smoke?

No, only smoke is immune to his bombs. No need to be rude. Probably a Christmas noob.

What does no smoke mean?

The expression “no smoke” is slang meaning the opposition wants “no conflict” or “no beef.” Rappers have used “Smoke” in lyrics like; “I want all the smoke” or “You don’t want no smoke.”

How does gas behave in space?

2 Answers. Gases tries to occupy all the volume of the container in which they are encased in equilibrated pressure. So, if the sealed container is opened up in space, the oxygen would quickly leak out, because the molecules near the vacuum edge would be instantaneosuly kicked out by the gas innermost molecules.

What happens when you release gas in space?

If you released air into space, it would form a large blob. The low pressure “blob” would hang around for awhile, and eventually dissipate into the vacuum surrounding it. When the oxygen tank ruptured on Apollo 13, it released a cloud of gas that was estimated to be twenty miles around.

What if space was filled with water?

Water poured into space (outside of a spacecraft) would rapidly vaporize or boil away. In space, where there is no air, there is no air pressure. As air pressure drops, the temperature needed to boil water becomes lower. In space, because there is no air pressure, water boils away at an extremely low temperature.

What happens when gas is cooled?

If a gas is cooled, its particles will eventually stop moving about so fast and form a liquid. This is called condensation and occurs at the same temperature as boiling. Evaporation is dependent on individual particles gaining enough energy to escape the surface of the liquid and become gas particles.
