  Why do our clothes appear darker when they get wet? Hi guys, I hope you all will be fine and enjoying. Today in this post we are going to know why do our clothes appear darker when they get wet. So, Let's start.... Any cloth is made from a yarn or fibre. That fibre in turn made of smaller micro-fibre. Some of the photons of light are absorbed but some are reflected and land on our retina and that gives us the sensation of seeing the cloth as having a certain level of brightness.  But when the cloth gets wet the water fills in the gaps between each individual microfiber or yarn. When light falls on the wet cloth, some of it is now more likely to enter the water and be bent away from our eyes. So, some of the light that would have previously been reflected off the cloth back to our eyes is now bent away. Fewer photons of light get back to our eyeball and so the wet cloth appears darker than the dry cloth. But as the water gradually evaporated more and more light is reflected b...

 How did the continents form.

Hi guys,

I hope you all will be fine and enjoying.Today in this post we are going to know how did the continents form?

 Three times during the past billion years drifting land masses have much to form supercontinents. 

 In between these stage of continental drift, they split into smaller land masses before recombining again. Scientists predict that a new super continent,Pangaea Ultima will eventually forms, 250 million years from now.
