The sound waves compress, causing the air molecules to be closer together as they propagate towards the hearer. This results in an increase in air pressure, which is perceived as a louder sound.
An object can accelerate towards the center without getting closer by changing its direction of motion. This is known as centripetal acceleration, where the object moves in a circular path around the center without moving closer to it.
The object moves in the direction of its motion.
the cold water moves down.
The object moves closer as it approaches the observer, narrowing the distance between them. This movement can create a sense of depth and proximity in the visual perception of the object.
The size and direction of a shadow change because they are influenced by the position of the light source relative to the object casting the shadow. When the light source is closer to the object, the shadow appears larger and the direction may shift. As the light source moves farther away from the object, the shadow size decreases and the direction changes accordingly.

it moves hot to cold.
The muscles that contract to bring two bones closer together are called flexor muscles. These muscles work by decreasing the angle between the two bones, resulting in movement such as bending the arm or leg.
packed together due to higher pressure, resulting in increased density. This causes the air to become heavier and more compact as it moves closer to the Earth's surface.

During muscle contraction, the Z line moves closer together, causing the muscle to shorten and generate force.
