A layer of gases surrounding the earth is called _____.

The layer of gases surrounding the Earth is called the atmosphere.

Our atmosphere is a mixture of gases that envelops the planet, held in place by Earth's gravity. It is essential for life, providing the air we breathe, protecting us from harmful ultraviolet radiation, and helping to regulate the planet's temperature. The atmosphere is composed of several layers, each with distinct characteristics:

• Troposphere: The lowest layer, where weather occurs and most of the atmosphere's mass is located.
• Stratosphere: Contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.
• Mesosphere: The layer where most meteorites burn up upon entering the atmosphere.
• Thermosphere: Characterized by a rapid increase in temperature with altitude; the International Space Station orbits within this layer.
• Exosphere: The outermost layer, where atmospheric particles are so sparse that they can travel hundreds of kilometers without colliding with one another.

Each of these layers plays a crucial role in maintaining the conditions necessary for life on Earth.
