Question

define atmosphere. why is it important? ​

Answer 1

Explanation:

Earth's Atmosphere

The atmosphere is a mixture of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth. High above the planet, the atmosphere becomes thinner until it gradually reaches space. It is divided into five layers. Most of the weather and clouds are found in the first layer.

The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun's dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.

Over the past century, greenhouse gases and other air pollutants released into the atmosphere have been causing big changes like global warming, ozone holes, and acid rain.

Lightning is the most spectacular element of a thunderstorm. A single stroke of lightning can heat the air around it to 30,000 degrees Celsius (54,000 degrees Fahrenheit)! This extreme heating causes the air to expand explosively. The expansion creates a shock wave that turns into a booming sound wave, better known as thunder.

➡️ Earth's atmosphere consists of about 78 % nitrogen, 21 % oxygen, 0.9 % argon, and 0.1 % other gases. Rest are of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 % .

➡️ There are 5 layers of the atmosphere, troposphere, stratosphere, mesosphere, thermosphere and exosphere.
