# In which layer of atmosphere rise of temperature rate is 53?

## In which layer of atmosphere rise of temperature rate is 53?

Mesosphere
Mesosphere. This layer extends from around 31 miles (50 km) above the Earth’s surface to 53 miles (85 km). The gases, including the oxygen molecules, continue to become denser as one descends. As such, temperatures increase as one descends rising to about 5°F (-15°C) near the bottom of this layer.

### What layer of the atmosphere is 12 to 50 km?

Stratosphere
Stratosphere. Located between approximately 12 and 50 kilometers (7.5 and 31 miles) above Earth’s surface, the stratosphere is perhaps best known as home to Earth’s ozone layer, which protects us from the Sun’s harmful ultraviolet radiation.

#### What layer of the atmosphere is 10 50 km?

stratosphere
– Thermosphere: The layer of very rare air above the mesosphere is called thermosphere. Many satellites actually orbit around the earth within this layer. Thus, the layer of atmosphere which is between 10 km to 50 km above the sea level is called the stratosphere.

What layer of the atmosphere is 53 372 miles high?

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 are the 7 layers of atmosphere?

The different layers of the atmosphere

• The Troposphere. This is the lowest part of the atmosphere – the part we live in.
• The Stratosphere. This extends upwards from the tropopause to about 50 km.
• The Mesosphere.
• The Thermosphere and Ionosphere.
• The Exosphere.
• The Magnetosphere.

## Where is the 50% of atmosphere?

Atmospheric pressure drops by 50% at an altitude of about 5 km (equivalently, about 50% of the total atmospheric mass is within the lowest 5 km). The average atmospheric pressure, at sea level, is about 101.3 kilopascals (about 14.7 pounds per square inch).

### What layer of atmosphere is 60 miles?

The mesosphere a layer extending from approximately 30 to 50 miles (50 to 85 km) above the surface, is characterized by decreasing temperatures. The coldest temperatures in Earth’s atmosphere occur at the top of this layer, the mesopause, especially in the summer near the pole.

#### What are the 9 layers of the atmosphere?

How many layers can you discover from the ground level up to 60 km?

The envelope of gas surrounding our planet Earth, known as the atmosphere, is organized into five distinct layers. These layers start at ground level, measured at sea level, and rise into what we call outer space.

What layer do planes fly in?

Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry air and contains little water vapor. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere.

## What is atmosphere 11th?

Answer: The atmosphere is composed of gases, water vapour and dust particles. The proportion of gases changes in the higher layers of the atmosphere in such a way that oxygen will be almost in negligible quantity at the height of 120 km.

### What makes up 21 of the air?

Air is mostly gas The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of other gases, too, such as carbon dioxide, neon, and hydrogen.

#### What layer does a helicopter fly?

Helicopters and light aircraft typically fly in the troposphere.

What layer are satellites?

You can consider most satellites to be in space, but in terms of the Earth’s atmosphere, they occupy regions called the thermosphere and the exosphere.

What is atmosphere Class 8?

The space around us is filled with air and dust particles. This layer of air surrounding the earth’s unit surface area is called the atmosphere. Atmospheric air extends many kilometres above the earth surface.

## What is atmosphere for Class 7th?

(i) What is the atmosphere? Answer: The blanket of air surrounding the earth is called the atmosphere. The atmosphere primarily comprises nitrogen and oxygen in bulk and other gases like carbon dioxide, helium, ozone, etc in lesser quantities. All living beings on earth depend on the atmosphere for their survival.

### What is 78 of the Earth’s atmosphere?

nitrogen
It’s a mixture of different gases. The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.

#### How many layers are there in the atmosphere of Earth?

Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.

What are the layers of the atmosphere from lowest to highest?

From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Troposphere. Earth’s troposphere extends from Earth’s surface to, on average, about 12 kilometers (7.5 miles) in height, with its height lower at Earth’s poles and higher at the equator.

What is the structure of the atmosphere?

Structure of the Atmosphere Unlike the changes in pressure and density, which decreases with altitude, the changes in temperature are irregular. A change in temperature with distance is called a temperature gradient. The Earth’s atmosphere is divided into layers based on the layer’s temperature gradient.

## How do the different layers of the atmosphere protect our planet?

These layers protect our planet by absorbing harmful radiation. Thermosphere 53–375 Miles – In the thermosphere, molecules of oxygen and nitrogen are bombarded by radiation and energetic particles from the Sun, causing the molecules to split into their component atoms and creating heat.
