Answer:
Spiral Galaxies, Elliptical Galaxies & Irregular Galaxies
Explanation:
How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.
Downwelling topic should be read by Pedro to understand the phenomenon.
Explanation:
The sinking and accumulation of high density material beneath the material of low density is the process of Downwelling. One such example is of- the saline water lies beneath the freshwater. It takes place in the oceanic anti-cyclonic areas where surface convergence is created.
It causes ventilation in oceans and helps in facilitating aerobic respiration in different organisms by bringing surface oxygen dissolved in water. This condition is the reason behind the survival of aerobic organism under water.
