Following are the different layers of the sun’s atmosphere. Rank them based on the order in which a probe would encounter them w
blsea [12.9K]

Answer:

Going from earth to the sun a probe would encounter the next layers in order:

  • Corona
  • Transition Region
  • Chromosphere
  • Photosphere
  • Convection Zone
  • Radiative Zone
  • Core

A brief description of them:

Corona is the outermost layer and it cannot  be seen with the naked eye, is starts at about 2100 km from the surface of the sun and it has no limit defined.

Transition Region is between the corona and the chromosphere, it has an extension of about 100km

The chromosphere is between 400 km from the surface of the sun to 2100 km. In this layer the further you get away from the sun it gets hotter.

The photosphere is the surface of the sun, the part that we can see, and extends from the surface to 400km.

The convection zone is where convection happens, hot gas rises, cools and rises again.

Radiative Zone is where the photons try to rise to move to higher layers.

The core of the Sun is where nuclear fusion occurs due to the very high temperatures.

What laws of motion are demonstrated by a hammer pounding a nail into a board?
julia-pushkina [17]
A hammer pounding a nail into a board is an example of Newton’s Third law.

Newton’s third law states that for every action there is an equal and opposite reaction. Meaning, when you hit the hammer on the board the same amount of energy that is going into the board, is going into the hammer. Causing the hammer to bounce off the board.

Hope this helps!
