What Is Atmosphere?


When writing a story, you must build imagery through descriptions that appeal to the reader’s five senses. They help the reader visualize the attributes of the story and add to the atmosphere. Another important part of writing an atmospheric story is the choice of diction. The choice of words you use can dramatically influence the tone and mood of the story. It can even influence how the reader feels about the story.


The atmosphere is the thin layer of air surrounding our planet. It protects our planet from the harmful rays of the sun. This blanket of air is composed of several different gases. Two of these gases are nitrogen and oxygen. When these gases change in composition, they form what is known as weather. This makes our planet habitable for humans.

There are five layers in the atmosphere. The lowest layer is known as the troposphere. The other two layers are the thermosphere and the exosphere. The temperature in each layer increases with altitude.


The layers of the atmosphere are made up of different gases and are separated by a boundary called the stratopause. The stratosphere is the lowest layer and is found 80 kilometres above the Earth’s surface. This layer absorbs ultraviolet and X-ray radiation from the sun. Its temperature can range from -90oC to 1500oC. It also protects us from meteors and burns up old satellites.

The outer atmosphere is the nearest to the surface of the Earth and is the densest layer of the atmosphere. It contains many different gases, including oxygen and nitrogen. Oxygen is the most abundant gas in this layer and makes up 21% of the outer atmosphere. The outer atmosphere is surrounded by other gases, which make up 0.04%.


The atmosphere is one of the most important components of our planet. It is responsible for sustaining life by providing oxygen and carbon dioxide. It also dissociates many waste products. The atmosphere is also a very important part of weather and climate. It also protects the earth from harmful ultraviolet radiation. In addition, it provides water, which is necessary for life.

The atmosphere is a complex structure with several layers. The first, known as the troposphere, is the lowest layer of the atmosphere. It comprises the ozone layer, which protects the earth from the sun’s harmful ultraviolet rays. The other layers are the stratosphere, mesosphere, and ionosphere.


A book’s tone and atmosphere affect how the reader experiences the story. It is important to consider how tone affects your readers’ perceptions of a story. The tone of a book will give the reader a sense of the character’s moods and how the story makes them feel. A book with a bleak tone will likely turn readers off. The opposite is true if the tone is upbeat and optimistic.

A good way to establish tone in a book is to use similes. For example, Ernest Hemingway uses a simile to show a lonely, failing character in The Old Man and the Sea. This simple example shows how tone can be set without needing to create 50 pages of detailed exposition. In addition, the tone can be set quickly.


Measurement of atmosphere refers to the process of measuring atmospheric pressure. This pressure is influenced by the temperature and the atmosphere’s composition. In the case of the Earth, one standard atmosphere is equal to the pressure exerted by 760 mm mercury at 32 deg F. In outer space, pressure is zero. But at the centre of massive bodies, the pressure is much higher.

One way to measure atmospheric gases is through spectroscopy. The method involves shining an electromagnetic beam through a sample of air. These beams can be visible, infrared, or ultraviolet. Microwaves can also be used to measure atmospheric gases. Because all atoms and molecules absorb light at certain wavelengths, they can be classified by their absorption patterns. This allows scientists to identify which substances are present and at what levels.
