What term describes the mesosphere?
Which term accurately describes the mesosphere? Extremely cold. In the name "thermosphere," the prefix "thermo" refers to what? Heat.
Is the mesosphere hot or cold?
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. Temperature decreases with height, reaching a minimum average value of -90 ºC at the top of the layer.

What is the mesosphere quizlet?
Mesosphere. The third layer of the atmosphere.
Is the mesosphere the lower mantle?
The mesosphere is beneath the asthenosphere. It encompasses the lower mantle, where material still flows but at a much slower rate than the asthenosphere. A layer of liquid iron and nickel (and other elements) beneath the mesosphere.
What is an example of a mesosphere?
The mesosphere is also the layer where most meteors burn up upon atmospheric entrance. This example is from Wikipedia and may be reused under a CC BY-SA license. The downwelling over the nightside causes adiabatic heating of the air, which forms a warm layer in the nightside mesosphere at the altitudes 90120 km.
Which statement is true for mesosphere?
The correct answer is Within the mesosphere, temperature increases with increasing height. It extends above the stratosphere up to a height of about 80 km. It is the coldest layer of the atmosphere.
What things are in the mesosphere?
Most meteors burn up in the mesosphere. A type of lightning called sprites sometimes appears in the mesosphere above thunderstorms. Strange, high-altitude clouds called noctilucent clouds sometimes form in this layer near the North and South Poles.
What is the another name of thermosphere?
The thermosphere (or the upper atmosphere) is the height region above 85 kilometres (53 mi), while the region between the tropopause and the mesopause is the middle atmosphere (stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near an altitude of 45 kilometres (28 mi) …
What is the stratosphere quizlet?
stratosphere (definition) layer directly above troposphere which contains ozone layer which protects earth from uv rays.
What is thermosphere quizlet?
Thermosphere. is the layer of the Earth's atmosphere directly above the mesosphere and directly below the exosphere. Within this layer ionization occurs. This is the area where satellites usually orbit the earth. Around 100km – 600km above the surface, or 6,471km-6,971km from the centre of the earth.
What state of matter is the mesosphere?
The mesosphere is entirely solid. The temperature and pressure of the rock in the mesosphere keep it from breaking; therefore, no earthquakes originate from the mesosphere.
What is the mesosphere composed of?
Together with the stratosphere, the mesosphere is referred to as the middle atmosphere. This layer is composed of oxygen, nitrogen, and carbon dioxide. As the distance from the Earth increases, the temperature of the mesosphere gets colders. It gets cold enough to freeze water vapor into ice clouds.
What makes the mesosphere unique?
The mesosphere is the coldest layer of the atmosphere which surrounds the Earth. It can reach five degrees Fahrenheit at its warmest but the further you travel away from the Earth, the colder it gets: the temperature in the mesosphere can reach -150 degrees Fahrenheit.
How thick is the mesosphere?
Mesosphere –The mesosphere is another rigid layer in the earth and it is roughly 2,200km in thickness. 4. Outer Core – The outermost layer of the core is liquid, and it is roughly 2,200km thick.
What are the layers of the atmosphere quizlet?
These layers are the troposphere, the stratosphere, the mesosphere, and the thermosphere.
What is the troposphere quizlet?
TROPOSPHERE. This is the layer of the atmosphere closest to the Earth's surface, extending up to about 10-15 km above the Earth's surface. It contains 75% of the atmosphere's mass. The troposphere is wider at the equator than at the poles. Temperature and pressure drops as you go higher up the troposphere.
Is the mesosphere solid or liquid or semi solid?
Mesosphere –The mesosphere is another rigid layer in the earth and it is roughly 2,200km in thickness. 4. Outer Core – The outermost layer of the core is liquid, and it is roughly 2,200km thick. 5.
Is the mesosphere solid?
Comprising the inner part of the mantle, the mesosphere is a region of very hot solid rock. Here, although hotter than the asthenosphere, the pressure is too high for liquid rock to form.
What are the atmosphere layers in order?
From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
- Troposphere. …
- Stratosphere. …
- Mesosphere. …
- Thermosphere. …
- Exosphere. …

Is the mesosphere liquid?
Comprising the inner part of the mantle, the mesosphere is a region of very hot solid rock. Here, although hotter than the asthenosphere, the pressure is too high for liquid rock to form.
What is the mesosphere made up of?
The mesosphere's atmosphere is low density and made up of oxygen, carbon dioxide, and nitrogen. Although most of the meteors that reach the mesosphere are burned up, some of their material hangs around afterwards, including iron and other metallic atoms.
Is the mesosphere solid or liquid?
Comprising the inner part of the mantle, the mesosphere is a region of very hot solid rock. Here, although hotter than the asthenosphere, the pressure is too high for liquid rock to form.
What’s the mesosphere made of?
The mesosphere's atmosphere is low density and made up of oxygen carbon dioxide and nitrogen. Although most of the meteors that reach the mesosphere are burned up some of their material hangs around afterwards including iron and other metallic atoms.
Which correctly describes the stratosphere?
The stratosphere (strato- simply means "layer" or "level") lies above the earth's weather and mostly changes very little. It contains the ozone layer, which shields us from the sun's ultraviolet radiation except where it's been harmed by manmade chemicals.
What makes up the mesosphere?
The mesosphere's atmosphere is low density and made up of oxygen, carbon dioxide, and nitrogen. Although most of the meteors that reach the mesosphere are burned up, some of their material hangs around afterwards, including iron and other metallic atoms.
Is the mesosphere solid rock?
Comprising the inner part of the mantle, the mesosphere is a region of very hot solid rock. Here, although hotter than the asthenosphere, the pressure is too high for liquid rock to form.
Why is mesosphere the coldest layer?
The mesopause is the point of minimum temperature at the boundary between the mesosphere and the thermosphere atmospheric regions. Due to the lack of solar heating and very strong radiative cooling from carbon dioxide, the mesosphere is the coldest region on Earth with temperatures as low as -100 °C (-148 °F or 173 K).
What does the mesosphere contain?
The mesosphere is the coldest layer of the atmosphere and decreases in temperature with altitude. It gets so cold that clouds called noctilucent clouds are composed of ice crystals. The coldest portion of the mesosphere is the mesopause which is the boundary that separates the mesosphere from the thermosphere.
Which layer is the mesosphere?
The middle layer The mesosphere lies between the thermosphere and the stratosphere. “Meso” means middle, and this is the highest layer of the atmosphere in which the gases are all mixed up rather than being layered by their mass. The mesosphere is 22 miles (35 kilometers) thick.
