The rotation of the Earth does not necessarily cause constant ripples and disturbances on the surface of calm bodies of water like lakes and ponds. There are a few reasons for this:
Inertia: Objects at rest tend to stay at rest unless acted upon by an external force. The water in lakes and ponds, unless disturbed by external factors such as wind or movement, tends to remain still due to its inertia. The rotational motion of the Earth does not exert a significant force to disturb the water's surface in the absence of other forces.
Scale and relative motion: The rotational speed of the Earth is relatively slow compared to the size of calm bodies of water. The Earth completes one rotation in approximately 24 hours, which translates to a relatively gradual rotational motion. The scale of lakes and ponds is much smaller, so the rotational speed difference between the Earth's surface and the water in these bodies is not significant enough to create noticeable disturbances.
Surface tension and viscosity: Water has surface tension, which is the cohesive force between its molecules at the surface. This surface tension helps to maintain the smoothness of calm water surfaces. Additionally, water has a certain viscosity or resistance to flow, which also contributes to the stability of the water's surface.
That said, it's important to note that bodies of water can experience ripples and disturbances due to various factors such as wind, tides, or local movements. These factors can create waves and ripples on the water's surface, even in relatively calm conditions. However, the rotation of the Earth itself is not the primary cause of these disturbances in calm bodies of water.
