Earth composition layers
WebNov 7, 2024 · Earth’s atmosphere has a layered structure. From the ground toward the sky, the layers are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Another layer, called the ionosphere, extends from the mesosphere to the exosphere. Beyond the exosphere is outer space. WebThe Earth's surface consists of a number of huge plates up to 100km thick which move at speeds between 2 and 15 cm a year. Volcanoes and earthquakes are largely the consequence of plate movement and often occur at the edges of these plates. Earth scientists have proposed that the Earth is constructed of layers.
