A plane flies at a height of 37,000 feet to avoid any hindrance due to weather conditions. In which layer of the atmosphere does the plane travel? A. thermosphere B. mesosphere C. stratosphere D. troposphere

The troposphere is the lowest layer of Earth's atmosphere. It starts at the Earth's surface and extends up to about 7 miles (11 kilometers) or less, depending on the location. This is where most of our weather occurs, including clouds, rain, and snow.
Temperatures in the troposphere generally decrease with altitude, making it colder as you go higher. The air is densest in this layer because it contains most of the atmosphere's total mass.
The boundary that separates the troposphere from the next layer, the stratosphere, is called the tropopause. Commercial planes generally fly at the upper levels of the troposphere or in the lower stratosphere to avoid turbulent weather.

The stratosphere lies above the troposphere and extends from about 7 miles (11 km) to 31 miles (50 km) above Earth’s surface. This layer is characterized by a gradual increase in temperature with altitude, due to the absorption of the Sun's ultraviolet radiation by the ozone layer.
The ozone layer is vital because it protects living organisms by filtering out harmful UV radiation. The stratosphere is relatively stable, with less turbulence compared to the troposphere. This is why commercial jets often cruise in the lower part of the stratosphere, around 30,000 to 39,000 feet.
Aircraft flying in the stratosphere can avoid most weather disturbances that occur in the troposphere below, making flights smoother and more efficient.

The mesosphere is the third layer, located above the stratosphere and below the thermosphere. It extends from about 31 miles (50 km) to 53 miles (85 km) high. In this layer, temperatures again decrease with altitude, making it the coldest part of the atmosphere.
One of the interesting features of the mesosphere is the phenomenon of noctilucent clouds, which are the highest clouds in the Earth's atmosphere, forming at altitudes of around 50 miles (80 km).
The mesosphere is also where most meteoroids burn up upon entering Earth's atmosphere, leading to the streaks of light we see as shooting stars. The boundary at the top of the mesosphere is called the mesopause, which is the coldest place in Earth’s atmosphere.

The thermosphere is the second highest layer in the atmosphere, located above the mesosphere. It starts around 53 miles (85 km) and extends several hundred miles up into space. Within this layer, temperatures rise dramatically due to the absorption of highly energetic solar radiation.
This layer is named the thermosphere because temperatures can get extremely high, even reaching up to 2,500°C (4,532°F) or more. However, despite high temperatures, the thermosphere wouldn't feel hot to us because the air density is so low.
The thermosphere contains the ionosphere, a sub-layer filled with charged particles that can reflect radio waves, making long-distance communication possible. The Northern and Southern Lights (Auroras) occur in the thermosphere, providing stunning natural light displays.
