Viruses could pass through bacterial filter which made belief that viruses are fluid.

<h3><u>Explanation</u>:</h3>

Contagium vivum fluidum is the term that was used by the scientists to describe the virus. The virus was first discovered by the scientist Beijernick who isolated the tobacco mosaic virus and as the tried to filter and separate the virus through the finest of the filters possible, he couldn't. So he said that virus are fluid in nature. Later Ivanovsky also gave the same postulate. He crystallized the virus too.

Coriolis

Convection currents flow due to variations in the temperature and salinity in seawater, which both influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.
