When charged particles from the sun strike atoms in Earth's atmosphere, they causeelectrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights
The viscosity of water is the thickness of water (it might also be considered the stickiness when talking about other fluids). Water has many properties, and the viscosity of water influences in many of them. We can take the surface tension of a liquid as an example. The more viscous a substance is, higher will the surface tension be and vice versa since there will be a higher and lower attraction between molecules respectively.
→ The surface tension of water is something really important since it contributes in many ways to the environment and if you think about it, if the water was a little less viscous, there wouldn't be water since the viscosity of water makes it resistant to evaporation to a certain degree.

The asthenoshere is a highly viscous, mechanically weak, ductile region of the upper mantle of Earth. Parts of it are made from rock melt.
The flowing asthenosphere carries the lithoshpere of the Earth, including the continents on its back.
