The correct answer is A. Mesosphere

It is the layer of the atmosphere that lies above the stratosphere and below the thermosphere. It is the coldest layer because the temperature decreases as you go higher in this part of the atmosphere. The mesosphere is where meteoroids burn up, creating what we see as shooting stars.

Importance of Mesosphere

  1. Protects us from space debris - The mesosphere helps burn up small space rocks and meteoroids before they reach Earth. This means we don’t get hit by too many meteor showers!
  2. Keeps our planet safe - It acts like a shield, protecting the lower layers of the atmosphere from harmful solar radiation. This helps keep our climate stable and safe for living.
  3. Helps with weather patterns - Even though it’s not where weather happens, the mesosphere affects how winds and weather patterns move by influencing air pressure and temperature.
  4. Shows us cool lights - You can see beautiful displays of auroras (Northern and Southern Lights) in this layer. It’s a pretty light show caused by particles interacting with the Earth’s magnetic field.
  5. Maintains balance in the atmosphere - By interacting with other atmospheric layers, the mesosphere helps keep the air in balance. This ensures that everything from the weather to the climate stays just right.

The coldest layer of the atmosphere is A. Mesosphere.

The Mesosphere is the coldest layer of the atmosphere, and knowing this helps us understand more about our environment and how it works.

Layer of the Atmosphere

1. Troposphere

  • Description - This is the layer closest to the Earth. It’s where we live and where all the weather happens (like rain, snow, and clouds).
  • Temperature - It gets colder as you go higher up, but it’s warmest near the ground.

2. Stratosphere

  • Description - Above the Troposphere, this layer contains the ozone layer, which protects us from the sun's harmful rays.
  • Temperature - In this layer, the temperature starts to get warmer as you go higher because of the ozone.

3. Mesosphere

  • Description - This is the middle layer of the atmosphere and the coldest one. It’s where meteors burn up when they enter the Earth’s atmosphere.
  • Temperature - It gets very cold, with temperatures dropping to around -90 degrees Celsius (-130 degrees Fahrenheit).

4. Thermosphere

  • Description - This layer is very high up and can get really hot, but it wouldn’t feel hot to us because the air is very thin.
  • Temperature - Temperatures can reach up to 2,500 degrees Celsius (4,500 degrees Fahrenheit) or more, but there aren’t enough air molecules to transfer that heat to us.

Why It Matters

  • Weather and Climate - Understanding these layers helps us predict the weather and study climate change.
  • Protection - The atmosphere protects us from harmful radiation and space debris.
  • Science and Exploration - Learning about these layers is important for scientists and astronauts who study the Earth and space.
