What is the role of polar stratospheric clouds on the destruction of ozone quizlet?

Polar stratospheric clouds (PSCs) play a central role in the formation of the ozone hole in the Antarctic and Arctic. These reactions lead to the production of free radicals of chlorine in the stratosphere which directly destroy ozone molecules.

What is special about the South Pole versus the North Pole that leads to ozone depletion?

What is special about the South Pole versus the North Pole that leads to ozone depletion only at the south Pole? Polar stratospheric clouds form almost exclusively at the South Pole. above the equator and above the Antarctic in its early fall. Ozone is removed by its reaction with water vapor.

Why does the concentration of ozone in the atmosphere drop at night in metropolitan areas?

In metropolitan areas, the concentration of ozone in the atmosphere drops at night. An inversion layer happens when a certain weather pattern traps cooler air near the surface of the earth with a warmer air mass above it.

Which product of the ultraviolet decomposition of CFCs acts as the catalyst for ozone decomposition group of answer choices?

When CFCs are released into the atmosphere they are not broken down immediately but are transported into the stratosphere, where they are eventually broken down by UV radiation. The breakdown of CFCs releases chlorine, which then acts as a catalyst for the destruction of the ozone layer.

What is the relationship between stratospheric levels of atomic chlorine and ozone quizlet?

What is the relationship between stratospheric levels of atomic chlorine and ozone? As chlorine increases, ozone decreases. [Chlorine (from CFCs) is the cause of the ozone holes.]

How polar stratospheric clouds cause ozone depletion?

These high altitude clouds form only at very low temperatures help destroy ozone in two ways: They provide a surface which converts benign forms of chlorine into reactive, ozone-destroying forms, and they remove nitrogen compounds that moderate the destructive impact of chlorine.

Which of the following chemicals are responsible for the depletion of the stratospheric ozone layer?

Chlorofluorocarbons (CFCs) and other halogenated ozone-depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

How does the concentration of ozone depend on the time of day?

In general, ozone levels are higher on hot, sunny summer days especially during episodes of stagnant air. Daily ozone levels can be influenced by local weather events, regional weather patterns and the presence of chemicals in the air that react to form ozone.

What affects ozone concentration?

Daily temperatures, relative humidity, and wind speed can affect ozone levels. In general, warm dry weather is more conducive to ozone formation than cool wet weather. Wind can affect both the location and concentration of ozone pollution.

How Stratospheric Ozone is formed?

Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2). The “ozone layer,” approximately 6 through 30 miles above the Earth’s surface, reduces the amount of harmful UV radiation reaching the Earth’s surface.

What does the Montreal Protocol deal with?

ozone layer
The Montreal Protocol, finalized in 1987, is a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS).

What was the Montreal Protocol quizlet?

What is the Montreal Protocol? A treaty among nations designed to protect the stratospheric ozone layer.
