The majority of the mass of the entire atmosphere is contained in the troposphere —between approximately 75 and 80 percent. Most of the water vapor in the atmosphere, along with dust and ash particles, are found in the troposphere—explaining why most of Earth’s clouds are located in this layer.
Which two layers of the atmosphere are responsible for the majority of solar?
Which two layers of the atmosphere are responsible for the majority of solar radiation absorption? The stratosphere and thermosphere . You just studied 10 terms!
Which two layers of the atmosphere are responsible for the majority of the solar radiation absorption the stratosphere and the troposphere the stratosphere and the thermosphere the mesosphere and the thermosphere the troposphere and the mesosphere?
The troposphere contains 75% of the atmospheric mass as well as the oxygen and carbon dioxide plants and animals need to survive. The stratosphere’s ozone layer absorbs ultraviolet radiation which is harmful to living organisms. The thermosphere absorbs solar radiation and helps to regulate the Earth’s temperature.
Which layer of the atmosphere is responsible for?
It’s in this layer that the majority of weather is determined /occurs. Above the troposphere is the stratosphere, which extends to a height of 50 kilometers (31 miles) and contains the ozone layer. The mesosphere is a thin layer above that, followed by the thermosphere. The thermosphere is also called the ionosphere.
What is the 2 highest layer of the atmosphere?
From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
What is the coldest layer of the atmosphere?
Mesosphere , coldest layer of Earth’s atmosphere.
Which two layers of the atmosphere are?
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere . A further region at about 500 km above the Earth’s surface is called the exosphere.
What is the hottest layer of the atmosphere?
The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km.
What is the main function of the atmosphere?
Atmosphere is essential for life on Earth as it supplies oxygen, water, CO 2 and some nutrients (N) to living organisms , and protects living organisms from temperature extremes and excessive UV radiation.
What is the uppermost limit of the atmosphere?
The exosphere is the outermost layer of Earth’s atmosphere (i.e. the upper limit of the atmosphere). It extends from the thermopause, 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), where it merges into the solar wind.
What layer do we live in?
The Troposphere
This is the layer we live in and contains most of what we consider to be “the atmosphere,” including the air we breathe and nearly all of the weather and clouds we see. In the troposphere, the temperature of the air decreases the higher you go.
Which layer of atmosphere is responsible for aurora formation?
The aurora (Northern Lights and Southern Lights) mostly occur in the thermosphere . The thermosphere is a layer of Earth’s atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet.
Can you breathe in the mesosphere?
The mesosphere lies between the thermosphere and the stratosphere. ... The mesosphere is 22 miles (35 kilometers) thick. The air is still thin, so you wouldn’t be able to breathe up in the mesosphere . But there is more gas in this layer than there is out in the thermosphere.
What are the 7 layers of earth?
If we subdivide the Earth based on rheology, we see the lithosphere, asthenosphere, mesosphere, outer core, and inner core . However, if we differentiate the layers based on chemical variations, we lump the layers into crust, mantle, outer core, and inner core.
Which layer contains the ozone layer?
Most atmospheric ozone is concentrated in a layer in the stratosphere , about 9 to 18 miles (15 to 30 km) above the Earth’s surface (see the figure below). Ozone is a molecule that contains three oxygen atoms. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.
Why mesosphere is 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 is warmed by that mechanism. ... Thus, the mesosphere lacks radiation absorption from below and above, making it the coldest layer.
