Does convection occurs in solids? explain why or why not plz answrrr

Convection CANNOT occur in a solid because, like the bricks in a wall, the atoms in a solid cannot move far from where they are. In liquids and gasses, however, the particles are free to move about (which is why a fluid can change its shape to match its container).

I hope this helps :)

a = executive branch; b = judicial branch

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
