Earth layer Our Earth is surrounded by layers such as the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the lowest layer in our Earth’s atmosphere, meaning it is closest to us, and it has an impact on our weather and climate. Above the troposphere is the stratosphere, which protects us from harmful ultraviolet (UV) radiation. The air movement in this layer is relatively slow. Beyond the stratosphere, we find the mesosphere, where temperatures are low, and meteorites and shooting stars burn up. The mesosphere has low pressure and serves as a protective barrier between space and Earth. Above […]
