What are the layers of atmosphere Class 6?

Atmosphere Layers

• > Troposphere.
• > Stratosphere.
• > Mesosphere.
• > Thermosphere.
• > Exosphere.

How many layers are in the atmosphere?

Earth’s atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere, according to NASA. The atmosphere thins out in each higher layer until the gases dissipate in space.

What is special about each layer of the atmosphere?

1) The troposphere is the first layer above the surface and contains half of the Earth’s atmosphere. Weather occurs in this layer. 2) Many jet aircrafts fly in the stratosphere because it is very stable. 5) The atmosphere merges into space in the extremely thin exosphere.

Which is the hottest layer of atmosphere?

The thermosphere
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. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).

What is the hottest layer of the atmosphere?

thermosphere

What is the thickest layer of the atmosphere?

troposphere
The atmosphere is divided into five different layers, based on temperature. The layer closest to Earth’s surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface. The troposphere is thickest at the equator, and much thinner at the North and South Poles.

What layer do we live in?

The Troposphere
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 is the coldest layer of the atmosphere?

the mesosphere
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).

Which is the thinnest layer of atmosphere?

Thermosphere is the thinnest layer of the atmosphere.

What are the four main atmosphere layers?

Scientists divide Earth’s atmosphere into four main layers classified according to changes in temperature. These layers are the troposphere, the stratosphere,- the mesosphere, and the thermosphere. troposphere . The troposphere is the layer of the atmosphere in which Earth’s weather occurs.

What is the hottest and coldest layer of the atmosphere?

The MESOSPHERE is the coldest layer and the THERMOSPHERE is the hottest layer in the atmosphere.

What is the highest layer of the atmosphere?

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.

What is the bottom layer of the atmosphere called?

Earth’s atmosphere consists of a number of layers that differ in properties such as composition, temperature and pressure. The lowest layer is the troposphere, which extends from the surface to the bottom of the stratosphere.
