When trees are cut on a large scale and they are unused, they slowly get deeper into the soil as more soil deposited over them they goes more deeper into the soil. Under the soil there is no air so that the temperature is so high and pressure will also high. Due to high temperature and high pressure the dead plants get converted into coal. This is how coal made from deforestation.

Kaleidoscope is a device based on multiple reflections. It consists of three long and narrow stripes of mirrors inclined at an angle of 60⁰ to one another forming a prism. This prism is fitted in a cylindrical tube. One end of this tube is closed by a cardboard disc having a hole at its centre. To the other end touching the mirrors a plane glass plate is fixed on which coloured pieces of glass are placed. This end of the tube is closed by a round glass plate. The Kaleidoscope is ready. When we see through the hole, we can see different patterns. An interesting feature of kaleidoscope is that we will not see any pattern again.
