Answer: the structure of an atom: At the center of the atom, there is a very small region called the nucleus. This area makes up most of the mass of the atom.
The area around the nucleus is called the electron cloud. This area makes up the majority of the volume of the atom. The electron cloud is mostly empty space.

Explanation:
<span>Depletion of the ozone layer. Choloroflourocarbon (CFCS) are dangerous because of their destructive reaction with Ozone particles, which provide the Earth with a protective layer or shield against UV radiation. Depletion of the ozone layer begins when when CFC gets into the stratosphere. Sunlight breaks up cfcs releasing Chlorine Atom. Chlorine atoms in turn react with Ozone, starting a chemical cycle that destroys the ozone layer in that area. Once the ozone layer is depleted, there's nothing holding back the harmful UVB wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere causing havoc on plants and animals.</span>
The width of the cloud is : 384 m
<u>Given data :</u>
Cloud altitude = 2200 m
Temperature = 10°
<h3>
</h3><h3>Determine how wide the cloud is </h3>
applying the equation below
I = d
where : I = linear size , d = 2200 m , 
therefore :
I = 2200 ( 10 / 57.3 )
= 383.94 m
≈ 384 m
Hence we can conclude that the width of the cloud is : 384 m
