What is atmosphere short answer for kids?
Earth's atmosphere is similar to a jacket for our planet. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere.
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.
atmosphere. noun. at·mo·sphere ˈat-mə-ˌsfi(ə)r. : the whole mass of air surrounding the earth. : a mass of gases surrounding a heavenly body (as a planet)
The atmosphere. is the layer of gas that surrounds Earth. It is often called air. Other planets, and some of their larger moons, also have atmospheres. The atmosphere consists of several different gases.
The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere.
(i) What is the atmosphere? Answer: The blanket of air surrounding the earth is called the atmosphere. The atmosphere primarily comprises nitrogen and oxygen in bulk and other gases like carbon dioxide, helium, ozone, etc. in less quantities.
The atmosphere is important for us because it provides air to breathe and protects us from the harmful effect of sun's rays.
The atmosphere is a mixture of gases that surrounds the Earth. It helps make life possible by providing us with air to breathe, shielding us from harmful ultraviolet (UV) radiation coming from the Sun, trapping heat to warm the planet, and preventing extreme temperature differences between day and night.
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth.
Atmosphere is often associated with dark moods and feelings, like suspense, tension, and horror, although it describes positive feelings equally well; “relaxed atmosphere” sounds perfectly normal, for example. Tone describes attitude, while atmosphere describes feeling.
What are 5 examples of the atmosphere?
Earth's atmosphere consists of five main layers from lowest to highest: troposphere, stratosphere, mesosphere, thermosphere and exosphere.
The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space.
atmosphere. a mixture of gases that surrounds earth-mostly made up of nitrogen, CO2,O2.
How can there be clouds in winter when it is too cold for water to stay a vapor? How do plants get their nitrogen from the air? How do trees give earth all its oxygen?
Answer. Answer: An atmosphere is a layer or a set of layers of gases surrounding a planet or other materials body, that is held in place by the gravity of that body.
The atmosphere contains the air that we breathe; protects us from the harmful radiation of the Sun; helps to keep the planet's heat on the surface, and plays a very important role in the water cycle.
Atmosphere is the thin layer of air that surrounds the earth. It is made up of various gases such as oxygen, nitrogen, carbon dioxides, dust particles and water vapour. The gravitational force of the earth holds the atmosphere around it. It protects us from harmful rays and scorching heat of the sun.
4th Grade Science: The Atmosphere - Chapter Summary
Our instructors have created these lessons and quizzes to help 4th grade students understand science topics related to the atmosphere, including high and low pressure, layers of the atmosphere and the water cycle.
Some parts of the atmosphere are hot or cold, depending on height. Starting from the surface and climbing straight up, the air gets colder in the troposphere, but then it becomes hotter, higher in the stratosphere. These changes of temperature are divided into layers. These are like layers of an onion.
Troposphere is considered as the most important layer of atmosphere. It is the lower most layer of the Atmosphere.
Is the atmosphere important essay?
The presence of the atmosphere is necessary to sustain all the types of life of the earth. ADVERTISEMENTS: It is the atmosphere that plays its role tending to equalize the temperature of the earth's surface. By its agency weather is produced which causes rock weathering.
atmosphere. This is a mixture of gases that surrounds Earth. In addition to containing the oxygen you need to breathe, it protects you from the sun's damaging rays and is always changing. air pressure. This is the measure of the force with which air molecules push on a surface.
It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of other gases, too, such as carbon dioxide, neon, and hydrogen.
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
The atmosphere is held around the Earth by gravity. Gravity pulls gas molecules in the atmosphere toward the Earth's surface, causing air pressure. Air pressure is the measure of the force with which air molecules push on a surface.
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.
Atmosphere is the overall mood of a story or poem. It's usually something readers can't quite put their finger on – not a motif or a theme, but a “feel” that readers get as they read. It's very difficult to define, but you know an atmosphere when you read it.
Atmosphere is another word for mood; it's the feeling a writer wants their readers to experience, like suspense or foreboding, longing or joy. Individual scenes can have a particular mood, while the overall novel has another mood those scenes contribute to.
- protects us from the sun.
- protects from metors.
- gives us oxygen and protein.
- allows us to stay alive.
- Ask students to go to the board and write their surprise/unknown facts.
- Have a class discussion about the surprises or unknown facts.
- Ask them to try to explain how our atmosphere protects us.
- If our atmosphere disappeared, what things which are currently happening on earth would continue to happen?
Do we live in atmosphere?
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth's atmosphere.
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere.
A common definition of space is known as the Kármán Line, an imaginary boundary 100 kilometers (62 miles) above mean sea level. In theory, once this 100 km line is crossed, the atmosphere becomes too thin to provide enough lift for conventional aircraft to maintain flight.
The Earth's atmosphere is important because it makes conditions on Earth suitable for life. 1) It has gases like oxygen and other gases that living things need to survive. 2) It keeps the Earth's temperature warm enough for water to exit as a liquid, which living things also need.
Atmosphere is the thin layer of air that surrounds the earth. It is made up of various gases such as oxygen, nitrogen, carbon dioxides, dust particles and water vapour. The gravitational force of the earth holds the atmosphere around it. It protects us from harmful rays and scorching heat of the sun.
The atmosphere is very important to life on Earth and does many things to help protect life and help life to survive. The atmosphere protects Earth like a big blanket of insulation. It absorbs the heat from the Sun and keeps the heat inside the atmosphere helping the Earth to stay warm, called the Greenhouse Effect.
Weather is what the sky and the air outside are like, such as cold and cloudy. The weather is more than just wind or rain, but also includes some stunning effects in the sky like rainbows, flashes of lightning, and sunsets.
Weather is defined as the state of the atmosphere at a given time and place, with respect to variables such as temperature, moisture, wind speed and direction, and barometric pressure.
It's a mixture of different gases. The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of other gases, too, such as carbon dioxide, neon, and hydrogen.
An atmosphere contains the air that we breathe and is a blanket of gases that surrounds Earth. It is held near the surface of the planet by Earth's gravitational attraction. A barometer is used to measure air pressure.
How old is the atmosphere?
(4.6 billion years ago)
As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes.
What is Weather? The day-to-day conditions of the atmosphere at a place with respect to elements like humidity, temperature, wind speed, rainfall, etc. is called the weather of that place. Weather can be cloudy, sunny, rainy, stormy or clear.
Weather is the state of the atmosphere at any given time and place with respect to wind, temperature, cloudiness, moisture, pressure, and other factors.
Weather describes conditions in the air outside. Temperature describes how hot or cold the air is. Temperature is measured with a thermometer. Clouds are made of liquid water drops that fall to Earth as rain.
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth.
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.
