tro · po ball
lowest region of the atmospherebounded by the Earth’s surface and the tropopause, the temperature decreases with increasing altitude.

What does troposphere mean?

: The least dense part of Earth’s atmosphere, where most weather changes occur, where temperature typically drops rapidly with altitude It extends from the Earth’s surface to the bottom of the stratosphere, at a height of about 7 miles (11 kilometers).

What is the literal meaning of troposphere?

use the noun troposphere when talking about The part of the atmosphere closest to the Earth’s surface. . . The word troposphere comes from the Greek root tropos, « turn or change ».

When was the term troposphere invented?

Troposphere (n.)

1914From French troposphère, literally « range of change », coined by French meteorologist Philippe Teisserenc de Bort (1855-1913), from Greek tropos « to turn, to change » (from PIE root *trep- « to turn around »)+ sphaira « sphere » » (see sphere).

What is the layer of air around the earth called?

We live at the bottom of an invisible ocean called atmosphere, a layer of gas around our planet. Nitrogen and oxygen make up 99 percent of the gases in dry air, while argon, carbon dioxide, helium, neon, and other gases make up only a tiny fraction.

What are the 7 layers of the earth?

If we subdivide the earth according to rheology, we see Lithosphere, Asthenosphere, Mesosphere, Outer Core and Inner Core. However, if we distinguish these layers based on chemical changes, we would divide the layers into crust, mantle, outer core, and inner core.

Which layer is closest to space?

There is no clear boundary between the atmosphere and space, but an imaginary line about 62 miles (100 kilometers) above the Earth’s surface, called the Carmen line, is usually where scientists say the atmosphere meets outer space. troposphere is the layer closest to the Earth’s surface.

Is the troposphere hot or cold?

this The troposphere is warmest at the bottom near the Earth’s surfaceThe top of the troposphere is coldest, and it meets the layer above (the stratosphere) in a boundary region called the tropopause. Temperatures drop as you move up through the troposphere.

What are the rock layers of the earth?

J is the rocky exterior of the earth. It consists of a brittle crust and the top of the upper mantle. The lithosphere is the coldest and hardest part of the planet.

What are some interesting facts about the troposphere?

In this lowest layer the air is the densest. In fact, The troposphere contains three-quarters of the mass of the entire atmosphere. The air here is 78% nitrogen and 21% oxygen. The last 1% consists of argon, water vapor and carbon dioxide.

Are we living in the troposphere?

We humans live in the troposphere, almost all weather occurs at this lowest level. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is in the troposphere. As you climb higher in the troposphere, the air pressure drops and the temperature gets cooler.

What is another name for the troposphere?

On this page you can find 12 synonyms, antonyms, idioms and related words for troposphere, such as: atmosphereMesosphere, lower atmosphere, outer mesosphere, stratosphere, thermosphere, stratosphere, ionosphere, troposphere, thermosphere, boundary layer, upper atmosphere and tropopause.

What is an example of the troposphere?

The troposphere is the lowest layer of the atmosphere, where water vapor, vertical winds, and temperature decrease with altitude.An example of the troposphere is layer below the tropopause. . It is characterized by convective air movement and large vertical temperature changes.

What happens in the troposphere?

The cycle occurs in the troposphere, starting at The sun evaporates a lot of water from the Earth’s surface Moisture is carried by wind to other areas. As the air rises, expands and cools, the water vapor condenses and forms clouds.

What does the troposphere do?

The troposphere contains about 85% of the total mass of the atmosphere.Tropospheric processes, such as the water or hydrological cycle (cloud and rain formation) and the greenhouse effect, meteorological and climate. Chemical composition determines air quality.

Which layer is the coldest?

middle layerAltitude and Temperature Characteristics

The top of the mesosphere is the coldest region of Earth’s atmosphere, as temperatures can drop locally to 100 K (-173°C).

Which layer is the hottest in the atmosphere?

thermosphere Often considered the « thermosphere » because it contains the warmest temperatures in the atmosphere. The temperature increases with altitude until the top of the thermosphere is estimated at 500 km. The temperature of this layer can be as high as 2000 K or 1727 ºC (Wallace and Hobbs 24).

Which place is the coldest?

Where is the coldest place on earth?

• 1) East Antarctic Plateau, Antarctica (-94°C)…
• 2) Vostok Station Antarctica (-89.2°C)…
• 3) Amundsen-Scott Station, Antarctica (-82.8°C) …
• 4) Denali, Alaska, USA (-73°C) …
• 5) Greenland Klink Station (-69.6°C) …
• 6) Oymyakon, Siberia, Russia (-67.7°C)

What’s in the thermosphere?

In the upper thermal layer, Atomic Oxygen (O), Atomic Nitrogen (N) and Helium (He) is the main component of air. Most of the X-ray and ultraviolet radiation from the sun is absorbed by the thermosphere. When the sun is very active and emits more high-energy radiation, the thermosphere becomes hotter and expands, or « expands. »

What’s in the exosphere?

The exosphere is mainly composed of polar Low-density hydrogen, helium, and some heavier molecules, including nitrogen, oxygen, and carbon dioxide, are closer to outside base. Atoms and molecules are so far apart that they can travel hundreds of kilometers without colliding with each other.

What is the layer furthest from Earth?

exosphere It is the region of the atmosphere furthest from the Earth’s surface.

How far is space from Earth?

What is a Carmen Line?Experts suggest the actual boundary between Earth and space lies just 18.5 miles (30 kilometers) above the surface to More than a million miles (1.6 million km) away.

How high is the thermosphere?

Between approximately 53 miles (85 kilometers) and 375 miles (600 kilometers) located in the thermal layer. This layer is called the upper atmosphere. Although the gas in the thermosphere is still very thin, it becomes denser as it descends toward Earth.
