What is a atmosphere in English language?

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.

What is the lower atmosphere?

Troposphere. Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.

What is the composition of the upper atmosphere?

The Composition Of The Upper Atmosphere According to The Dissociation Of Oxygen And Nitrogen Molecules. We show that the observation of forbidden lines in the spectra of the night sky and of aurorae requires that the upper atmosphere should be composed essentially of atomic oxygen and nitrogen.

What is the upper atmosphere composed of?

The exosphere is the highest layer of Earth’s atmosphere and extends from the top of the thermosphere approximately 6,200 miles (10,000 km) above Earth’s surface according to NASA. The exosphere is composed of particles of hydrogen and helium, that are so widely dispersed they rarely collide.

What are the 4 layers of the Earth’s atmosphere?

From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

How does the upper atmospheric circulation influence the climate?

How does atmospheric circulation affect the climate? Atmospheric circulation creates winds that distribute heat and moisture across the surface of the planet. Together with surface ocean currents, it carries moisture from the oceans over large swathes of land.

What types of atmosphere are there in writing?

• Gloomy.
• Humorous.
• Melancholy.

• Whimsical.
• Romantic.

Why is the upper atmosphere cold?

The reason it is “cold” in the upper atmosphere is actually because of a lower air density. Remember that our concept of “temperature” as measured by a thermometer is actually the energy of the collisions between atoms.

How many atmospheres are there?

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 the uppermost layer of the atmosphere?

the exosphere
The uppermost layer, that blends with what is considered to be outer space, is the exosphere.

What is the upper limit of the earth’s atmosphere?

The ionosphere is a critical link in the chain of Sun-Earth interactions. This region is what makes radio communications possible. This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km (6,200 mi).

What are the types of atmosphere?

From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

• Troposphere.
• Stratosphere.
• Mesosphere.
• Thermosphere.
• Exosphere.
• The Edge of Outer Space.

Which is true of upper atmospheric circulation?

Which is true of upper atmospheric circulation? Middle and upper tropospheric circulation is an important component of the atmosphere’s general circulation.

What is the importance of atmospheric circulation?

Atmospheric circulation transports heat over the surface of the Earth that affects the water cycle, including the formation of clouds and precipitation events. The movement of air masses brings us our daily weather, and long-term patterns in circulation determine regional climate and ecosystems.

What’s the atmosphere of a story?

A literary technique, atmosphere is a type of feeling that readers get from a narrative, based on details such as setting, background, objects, and foreshadowing. A mood can serve as a vehicle for establishing atmosphere.

A dark tone, like in Frankenstein, can suggest terror, desolation, tension, or suspense.

What is the upper atmosphere made up of?

The upper atmosphere includes the mesosphere, the ionosphere, the thermosphere, and the exosphere. Temperatures in the upper atmosphere decrease with increasing altitude except in the thermosphere, where temperatures increase significantly with altitude, because the few molecules present receive intense solar radiation.
