What is the coldest altitude?
The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere. Temperatures in the upper mesosphere fall as low as −101 °C (172 K; −150 °F), varying according to latitude and season.
At what altitude is the coldest point in the atmosphere?
The mesosphere lies above the stratosphere and extends to an altitude of about 85 km (Ahrens 13). This is layer is often referred to as the cold layer, as the lowest readings in the atmosphere are found here.
What is the coldest air temperature in the atmosphere?
The lowest air temperature ever measured by a weather station, minus 89 degrees Celsius (minus 128 degrees Fahrenheit), was recorded there at Russia's Vostok Station in July 1983.
What is the altitude of each layer of the atmosphere?
Exosphere: 700 to 10,000 km (440 to 6,200 miles) Thermosphere: 80 to 700 km (50 to 440 miles) Mesosphere: 50 to 80 km (31 to 50 miles) Stratosphere: 12 to 50 km (7 to 31 miles)
Why is it colder at altitude?
High-altitude locations are usually much colder than areas closer to sea level. This is due to the low air pressure. Air expands as it rises, and the fewer gas molecules—including nitrogen, oxygen, and carbon dioxide—have fewer chances to bump into each other.
Which is the coldest region?
What is the coldest place on Earth? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.
Which is the coolest layer of the earth?
The lithosphere is the coolest layer of the Earth in terms of temperature, with the heat from the lower layers generating the plate movements.
What is the coldest temperature?
The coldest temperature ever measured was -126 Fahrenheit (-88 Celsius) at Vostok Station in Antarctica.
What is the coldest temperature possible?
At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.
Which is the coldest layer?
Mesosphere Mesosphere, altitude and temperature characteristics The top of the mesosphere is the coldest area of the Earth's atmosphere because temperature may locally decrease to as low as 100 K (-173°C).
What are the temperatures of the layers of the atmosphere?
The temperature ranges from negative 5 degrees Fahrenheit (negative 15 degrees Celsius) at the stratosphere boundary to negative 184 degrees Fahrenheit (negative 120 degrees Celsius) at the upper boundary.
Is 8000 feet high altitude?
High altitude: 8,000 to 12,000 feet above sea level. Very high altitude: 12,000 to 18,000 feet. Extremely high altitude: 18,000+ feet.
What place is the coldest?
What is the coldest place on Earth? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.
What is the coldest temperature in?
The coldest temperature ever measured was -126 Fahrenheit (-88 Celsius) at Vostok Station in Antarctica.
Where is the coldest temperature right now?
Antarctica Taking the prize as “the coldest place on Earth” right now is the South Pole in Antarctica, where temperatures are currently sitting at a cool -38.
What is the altitude of the thermosphere?
The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.
What is the coldest temperature in the stratosphere?
Temperatures range from an average of −51 °C (−60 °F; 220 K) near the tropopause to an average of −15 °C (5.0 °F; 260 K) near the mesosphere. Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night (winter).
Where is coldest place on Earth?
This map of Antarctica shows the massive East Antarctic Plateau, which includes Dome Argus and Lake Vostok, two of the coldest places on record in the world. When you go higher or lower, the measured temperature at your location may change. Surface temperatures are a different beast altogether.
Why is the atmosphere the coldest layer?
The mesosphere is the coldest layer because it has essentially nothing to heat it. The atmosphere is primarily heated from below, and the troposphere…
What would be the coldest temperatures in the stratosphere?
Temperatures range from an average of −51 °C (−60 °F; 220 K) near the tropopause to an average of −15 °C (5.0 °F; 260 K) near the mesosphere. Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night (winter).
What is the temperature at high altitude?
High altitude is defined as an elevation of 3,000 feet or more above sea level. Even at elevations of 2,000 feet, the temperature of boiling water changes from the standard 212°F at sea level to 208°F. Boiling or simmering foods at high altitude means lower temperatures and longer cooking times.
What was the coldest temperature ever recorded?
Scientists just broke the record for the coldest temperature ever measured in a lab: They achieved the bone-chilling temperature of 38 trillionths of a degree above -273.15 Celsius by dropping magnetized gas 393 feet (120 meters) down a tower.
Which city is coldest in world?
Oymyakon, a Russian settlement of around 500 people, reached a frosty minus 96.2 F (minus 71.2 C (opens in new tab)) in 1924.
Where is the coldest place in the world?
Antarctica What is the coldest place on Earth? It is a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.
What is the absolute coldest temperature?
minus 459.67°F. Physicists acknowledge they can never reach the coldest conceivable temperature, known as absolute zero and long ago calculated to be minus 459.67°F.
What is the altitude of troposphere?
The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high.
What is the altitude of the stratosphere?
around 31 miles Stratosphere. The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth's surface. This layer holds 19 percent of the atmosphere's gases but very little water vapor. In this region the temperature increases with height.
Which is the coldest and hottest layer of atmosphere?
The coldest layer of atmosphere is the mesosphere while the hottest layer of the atmosphere is thermosphere.

What is the altitude range for the troposphere?
4 to 12 miles 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.
