    Solids have definite shapes.This is because
    Any matter that is a solid has a definite shape and a definite volume. The molecules in a solid are in fixed positions and are close together. Although the molecules can still vibrate, they cannot move from one part of the solid to another part. As a result, a solid does not easily change its shape or its volume.

    Which best describes how air moves during convection?
    In convection, hot air rises from the Earth’s surface and becomes cold at higher altitude because of lower temperature there. As it cools, it sinks down to the surface of the Earth. On reaching Earth, it warms again and rises up again. The main reason for this phenomenon is – sinking cold air pushes the warm air up.
