In order to keep up with the tidal force of the moon, the tidal bulge waveform moves across earth's oceans at a speed of about 1,600 KM per hour.
The tidal bulge waveform is the distortion of water and Earth that we call a tidal bulge is a result of deformation of earth and water materials at different places on Earth and response to the combined gravitational effect of Moon and sun. It is two ocean bulges created on opposite sides of Earth due to the moon's gravitational pull and the ocean's resistance to the pull.
High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.

Explanation:
The Varnas system began during the Aryan invasion of India. The Varna system, which is known as the caste system, divides society into 4 categories:
- Brahmins are educators like scholars, teachers, gurus; and spiritual leaders such as priests.
- Kshatriyas are the "warriors" whose roles are to protect society. The term can be translated as "authority," so these people are usually kings, rulers and the like.
- Vaishyas are productive class, or simply the businessmen. They are in charge of agricultural businesses and trading. They ensure the wealth of the society.
- Shudras are coined as the unskilled workers. They are in a sense, the "servers". They tend to the higher classes and work for them and are expected to remain loyal to them.
