What is the sublayer of the atmosphere?
IONOSPHERE
A. A SUBLAYER OF THE TERMOSPHERE IS THE IONOSPHERE. THE IONOSPHERE IS MADE OF ELECTRICALLY CHARGED GAS PARTICLES (IONIZED) BY THE ABSORPTION OF RADIATION. THE IONOSPHERE EXTENDS FROM 60-300 Km ABOVE THE EARTH.
What are the three atmosphere on earth?
The three major constituents of Earth’s atmosphere are nitrogen, oxygen, and argon. Water vapor accounts for roughly 0.25% of the atmosphere by mass.
What is the third main layer of Earth’s atmosphere?
mesosphere
The third layer of Earth’s atmosphere, the mesosphere extends from around 31 to 50 miles high (the height at which you are considered an astronaut by U.S. standards).
Which layer of the atmosphere is divided into 2 sub layers?
thermosphere
The thermosphere is divided into two sub-layers. The lower layer, called the ionosphere (eye AHN uh sfeer), begins about 80 kilometers above the surface and extends to about 400 kilometers. Energy from the sun causes gas molecules in the ionosphere to become electrically charged particles called ions.
What is the largest layer of Earth’s atmosphere?
Exosphere
Exosphere. Located between about 700 and 10,000 kilometers (440 and 6,200 miles) above Earth’s surface, the exosphere is the highest layer of Earth’s atmosphere and, at its top, merges with the solar wind.
What are the five layers of the atmosphere?
These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth’s surface, is called the exosphere.
What is in the mesosphere?
At the bottom of the mesosphere is the stratopause, the boundary between the mesosphere and the stratosphere below. Most meteors vaporize in the mesosphere. Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms.
What is the order of layers in atmosphere?
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.
