The Mesosphere: Earth's Middle Layer

The Mesosphere: Earth's Middle Layer

The mesosphere is the third layer of Earth's atmosphere, extending from about 50 to 85 kilometers (31 to 53 miles) above the planet's surface. It's a crucial layer for several reasons:

Key Characteristics:

• Temperature Decrease: Unlike the layers below it, the mesosphere experiences a decrease in temperature with increasing altitude. In fact, the coldest part of Earth's atmosphere is located near the top of this layer.
• Meteor Burning: The mesosphere is where most meteors burn up as they enter Earth's atmosphere, creating the beautiful streaks of light we call shooting stars.
• Noctilucent Clouds: These rare, high-altitude clouds form in the mesosphere during summer months in polar regions. They are illuminated by sunlight after sunset and are visible to the naked eye.

The Role of the Mesosphere:

While the mesosphere might seem distant and inhospitable, it plays a crucial role in protecting Earth from harmful radiation and space debris. It's a vital part of our planet's complex atmospheric system.
