The two basic factors which are most important in determining the current appearance of a star are its mass and its stage of life. Stars are born with 75% Hydrogen and 25% Helium, with no more than 3% of that being heavier elements. A star burns its supply of elements over its lifetime, the larger the mass of the star then the greater it's brightness, luminosity and surface temperature will be. Dependant on the stage of the star's life, the color of the light will change.
Answer: The Moon's gravity causes ocean to bulge.
Explanation:
Ocean bulge occur when the gravitational attraction between earth and the moon causes the water in the oceans which can move to be attracted towards the moon. This causes a bulge in the ocean that is closest to the moon as the earth rotates and the location of the effected water changes.
