WebbOne definition of the outermost limit of the exosphere places the uppermost edge of Earth's atmosphere around 190,000 km (120,000 miles), about halfway to the Moon. At this distance, radiation pressure from sunlight exerts more force on hydrogen atoms than does the pull of Earth's gravity. WebbOr is it something in between, a kind of a putty-like non-rigid, solid layer? So let's think about it on the chemical or the compositional side first, because to some degree this is simpler. So the outermost layer is the crust. That's the layer that we're sitting on right here, right now, I'm assuming. I'm assuming you're on the planet.

WebbThis is the outermost layer of the atmosphere. It extends from the top of the thermosphere to 6,200 miles (10,000 km ) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth. 2. what is the outermost layer of the earth brainly. Answer: The outermost layer, called the crust, is solid, too. WebbOur planet Earth is composed of several layers. Each layer has a unique density (density = mass/volume). Scientists believe that all planets formed on the basis of gravity. Therefore, the layering of Earth is a result of gravitational pull. The densest layer (inner core) is at the center and the least dense layer (crust) is the outermost layer.
