What makes atmosphere unique?

The abundance of oxygen in our atmosphere and the presence of liquid water on the surface of our planet makes our “Pale Blue Dot” stand out in contrast to the other planets in the solar system — a unique and fragile home for life.

What are 4 facts about the atmosphere?

Beyond the troposphere are the stratosphere, the ozone layer, the mesosphere, and the thermosphere. The atmosphere is made up of 78% nitrogen, 21% oxygen, and smaller amounts of argon, carbon dioxide, helium, and neon. Contaminants in the atmosphere can include smoke, toxic gasses, dust, ash from volcanoes, and salt.

What are 4 things the atmosphere does for us?

Atmosphere basics

• protects us from the sun.
• protects from metors.
• gives us oxygen and protein.
• allows us to stay alive.

What are the 4 types of atmosphere?

The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere.

What are the 5 types of atmosphere?

Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

What is our atmosphere made of?

Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

What are 5 things in the atmosphere?

According to NASA, the gases in Earth’s atmosphere include:

• Nitrogen — 78 percent.
• Oxygen — 21 percent.
• Argon — 0.93 percent.
• Carbon dioxide — 0.04 percent.
• Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.

What are the 3 functions of the atmosphere?

The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth’s surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation …

What are 2 examples of the atmosphere?

Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse.

What are the main characteristics of the atmosphere?

Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.

How is the atmosphere unique to the Earth?

We might take the air we breathe for granted, but the Earth’s atmosphere is a product of billions of years of finely tuned evolution. Earth’s atmosphere is unique among all the planets and moons we know, both in our own solar system and in others light years away.

How many atmospheres have there been on Earth?

Earth Has Had Three Atmospheres The second atmosphere formed during the Hadean Aeon around 4 billion years ago. Today’s atmosphere consists of 78% nitrogen, 21% oxygen and traces of various other elements and compounds, including varying amounts of water vapour.

What are the different layers of the atmosphere?

We tend to divide the Earth’s atmosphere into five different layers. These are the exosphere, thermosphere, mesosphere, stratosphere and troposphere. The further you get out from Earth, the thinner the atmosphere is.

How is the atmosphere a product of evolution?

It’s the product of 4.7 billion years of evolution, shaped by everything from its proximity to the Sun to the rise of photosynthetic life. Without our cherished atmosphere, our planet would be lifeless, baked by the scorching rays and radiation of the Sun during the day and frigidly cold during the night.
