You can see smell and taste microorganisms

You can see the microorganisms through microscopes. However, smelling and tasting microorganisms depends on some situations and some microorganisms.

Explanation:

Microorganisms are very small beings, invisible to the human eye and therefore can only be viewed with the aid of the microscope. In other words, you can't see microorganisms with the naked eye.

In most cases it is not possible to smell or taste the microorganisms, but it is possible to smell and taste the organic matter that has been degraded by them. You will not be able to taste and smell food-degrading bacteria, for example. However, you can smell microorganisms that metabolize the sweat on your skin, cause mold and infect nails.

the plates spread at mid-ocean ridges (they are divergent plate boundaries) which allows magma to rise through the weakness between the plates. the magma then emerges as lava from the boundary and cools, creating a new crust.
