If you are talking about the Mesosphere of the atmosphere, then it is a gas. A liquid or solid layer would be too dense for the atmosphere to hold up, and it'd fall back to Earth's surface. That is also why rain falls and does not float.
mesosphere
The Troposphere, Stratosphere, Mesosphere and Thermosphere are gases. These are the layers that make up the atmosphere. The Hydrosphere is a liquid (H2O) and the Lithosphere is a solid. (Hope this helps!) :)
Broadly speaking the earth is solid in all layers except the outer core which is a liquid. However there are mechanical differences in the behaviour of the solid layers in that some (such as the lithosphere) are brittle whereas the asthenosphere and mesosphere are ductile.
gas
Solid --> Liquid = melting Other changes of state: Solid --> Gas = sublimation Gas --> Solid = deposition Liquid --> Solid = freezing/solidification Gas --> Liquid = condensation Liquid --> Gas = vaporization
The mesosphere is a layer of the atmosphere. As such it is gaseous.
Liquid and solid
because it is not in liquid state
Because the outer core is made out of different materials than the mesosphere. ;)
Iy is all just a gas
the upper mantle (lithosphere) which is solid in nature and the lower Mantle (mesosphere)which is liquid in nature
It is the Mesosphere
It is the Mesosphere
Solid
niether. The mesosphere is a layer of the atmosphere of earth, so it would be a gas. It is the coldest layer of the atmosphere reaching temperatures of -90 C. by mjjm23: No, it is a layer of the earth!! that is wrong, but i don't know the answer! THE ANSWER IS SOLID!!!!!!!!!!!!!!!!!!!! BECAUSE OF THE PRESSURE IN THAT AREA OF THE EARTH IN COMPARISON TO THE MATERIALS IN THE MESOSPHERE. THE MESOSPHERE IS SOLID. BUT YES THE MESOSPHERE IS ALSO THE NAME OF AN ATMOSPHERIC LAYER. BUT IN THE EARTH IT IS SOLID...
The mesosphere
Okay, the answer is this. There is the inner core. The inner core is solid. Then the outer core. The outer core is liquid. Then the Mesosphere. Then the Asthenosphere. Then finally the Lithosphere.
