- 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. The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), are found near the top of this layer. The boundary between the mesosphere and the thermosphere above it is called the mesopause. At the bottom of the mesosphere is the stratopause, the boundary between the mesosphere and the stratosphere below.

What Is the Hottest Layer of the Atmosphere? Quick Answer. The thermosphere is the hottest layer of the atmosphere. It extends from 80 kilometers above the surface of the Earth up to 600 kilometers and can heat up to 1,500 degrees Celsius because it’s very sensitive to solar activity. The air is thin and extremely hot, and there are sparse air molecules in this layer.

Earths Atmosphere Layers The exosphere is the highest layer of the atmosphere. It extends up to 10,000 km (6,200 miles; 33,000,000 ft.) above the Earth. Satellites orbit the Earth in the exosphere. The atmosphere in this layer is extremely thin and atoms and molecules of air are constantly escaping into outer space.

Which parts of Earth have yet to be explored by mankind in 2014? Antartica: Antarctica is the most coldest place on Earth surface, climate change between -10C to -30C in normal case, -89 degree celsius is the lowest ever recorded temperature. This harsh climate itself make Antarctica to most unknown and unexplored place.

What is Atmosphere? - Layers, Gases & Pressure Next up, the mesosphere starts just above the stratosphere, 31 miles (50 km) above the surface and extends up to 53 miles (85 km). The mesosphere is the coldest layer of the atmosphere with temperatures averaging -130° F (-90° C). Most of the meteors that burn up in the atmosphere do so in the mesosphere.

Layers of the Atmosphere The thermosphere rises several hundred miles above the earth's surface, from 50 miles up to about 400 miles. Temperature increases with height and can rise to as high as 3,600°F (2000°C). Nonetheless, the air would feel cold because the hot molecules are so far apart. This layer is known as the upper atmosphere.xtending from the top of the thermosphere to 6200 miles (10,000 km) above the earth is the exosphere. This layer has very few atmospheric molecules, which can escape into space. Pauses...: Between each layer of the atmosphere is a boundary.

Earths Atmosphere Layers Lower boundary is the surface of the Earth. The upper boundary varies between 7 km (23,000 ft.) above the poles and 14 km (56,000 ft.) above the equator. This is the layer of the atmosphere where we live. The troposphere contains 75% of the total mass of the atmosphere. The air cools 6.5°C for each kilometer above sea level.

Atmosphere of Earth The exosphere is the outermost layer of Earth's atmosphere (i.e. the upper limit of the atmosphere). It extends from the exobase, which is located at the top of the thermosphere at an altitude of about 700 km above sea level, to about 10,000 km (6,200 mi; 33,000,000 ft).he common name air is given to the atmospheric gases used in breathing and photosynthesis. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.

What Is the Coldest Layer of the Earth's Atmosphere? What is the coldest layer of the Earth's Atmosphere? A: Temperatures can reach lows of -90 degrees Celsius in the mesosphere, making it the coldest layer of the earth's atmosphere. The mesosphere extends above the stratosphere and ranges from 50 km to 87 km above the surface.

- But how cold can it get on Earth’s surface? What sort of weather brings on the record-breaking cold? On the high plateau of East Antarctica, there is a ridge along the ice sheet nearly 14,000 feet above sea level. The dry atmosphere and the long, sunless winter months combine to make this the coldest place on earth. Under the clear Antarctic night skies the snow surface radiates warmth into space, cooling the air just above the surface. As the air cools, it gets denser and starts to slide down the slope off of the ridge.

Layers of Earth's Atmosphere In many ways, the thermosphere is more like outer space than a part of the atmosphere. Many satellites actually orbit Earth within the thermosphere! Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. Because of this, the top of the thermosphere can be found anywhere between 500 and 1,000 km (311 to 621 miles) above the ground. Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher. The aurora, the Northern Lights and Southern Lights, occur in the thermosphere. Exosphere

The _______ is the coldest layer of the atmosphere. a. troposphere b. stratosphere c. mesosphere d. thermosphere The correct answer is Mesosphere, and more specifically the region where Mesophere becomes Thermosphere (Thermosphere itself is pretty warm, ,with temperatures up to 2000 degrees!)/ This region is Mesopause: so an even better answer than Mesosphere is Mesopause.

Coldest spot on Earth identified by satellite Image caption Antarctica's dry and clear conditions allow heat to be radiated very efficiently out into space. The coldest place on Earth has been measured by satellite to be a bitter minus 93.2 Celsius (-135.8F). As one might expect, it is in the heart of Antarctica, and was recorded on 10 August, 2010.

- The coldest layer of the atmosphere is in the Mesosphere. This is because temperatures are decreasing as the Mesosphere extends upward above the Stratosphere. The air is thinn…er because the air particles are further apart. The next layer, known as the Thermosphere is the hottest layer.

- The coldest temperature ever recorded on earth is -89.2 degrees Celsius (-128.5 degrees Fahrenheit) at Vostok, Antarctica on July 21, 1983. That all-time low broke the previous world-record minimum of -88.3 °C (-126.9 °F), set on August 24, 1960, also at Vostok.

Layers of the Atmosphere The Ionosphere. Exosphere. The Exosphere is the outermost layer of the atmosphere. It extends from the thermopause-the transition boundary which separates the exosphere from the thermosphere below-to 6,200 miles (10,000 km) above the earth.tratosphere. The Stratosphere extends from the tropopause up to 31 miles above the Earth's surface. This layer holds 19 percent of the atmosphere's gases but very little water vapor. Temperature increases with height as radiation is increasingly absorbed by oxygen molecules leading to the formation of Ozone.

Layers of Earth's Atmosphere Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the exosphere to be the actual final frontier of Earth's gaseous envelope. As you might imagine, the air in the exosphere is very, very, very thin, making this layer even more space-like than the thermosphere. In fact, air in the exosphere is constantly - though very gradually - leaking out of Earth's atmosphere into outer space.
