The movement of tectonic plates causes earthquakes when two plates that are in contact with each other move in opposite directions and release built-up stress.<span>For example, one plate may move north, while the other may move south. Stress can build up to a significant amount while the plates are held stationary, but trying to move, which can then be released as an earthquake</span>
When a match stick is struck, some of the chemical energy is transformed into heat and light and the rest is converted into matter. A match stick has a lot of chemical energy stored in it. When its struck, It start burning. The chemical energy stored in it is transformed into heat energy and light energy. The rest of it turn into ashes and reaction gases.
Speed of sound through a medium depends on ● temperature ● density of medium ● speed of wind ● humidy ● moisture Speed of sound increases with increase in temperature. Because when temperature increases the molecules get higher energy and they vibrate quickly. Due to this vibration sound waves can travel fastly.
