Which one of the following statements best explains why convection doesn't occur in solids? group of answer choices solids are less compressible than gases. the molecules in a solid vibrate at a lower frequency than those of a liquid. solids are more compressible than liquids. the molecules in a solid are more closely spaced than in a gas. the molecules in a solid are not free to move throughout its volume.

Option (e) is the correct answer.

Explanation:

Convection is defined as the process in which a fluid (liquid or gas) when heated then more dense (cooler) substance sinks at the bottom whereas less dense (hotter) substance will rises at the top.  

This intermixing of the substances tends to generate convection currents and this process is known as convection.

Since, particles in a solid are strongly held together due to which they are unable to move from their initial position.

Thus, we can conclude that the statement molecules in a solid are not free to move throughout its volume best explains why convection doesn't occur in solids.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.
