Look! That meteorite sparkled! That might hold diamonds!

Have you seen the sparkly rocks? No, the transparent ones. Those are called diamonds. Have you ever wondered how these precious stones are made? Currently, there are four theories about it.

Scientists and geologists believe that the diamonds formed underground was sent upwards by the volcanoes. The lava that flows  out carries the diamonds. This is evident because of the tiny diamonds in the rocks near the volcanic sites.

The second theory is that there are diamonds are found under tectonic plates. The temperature and the pressure formed inside tectonic plates made small diamonds. This is evident from the diamonds that are found in a subducted tectonic plate.

The third theory is that the Earth was hit by asteroids. These space rocks hit the ground causing it to have high pressure and temperature, thus forming the diamonds. Evidence was that several diamonds were found in asteroid crash sites.

NASA has also detected and seen very tiny diamonds in the meteorites. The tiny diamonds are called nanodiamonds. The nanodiamonds aren't actual crystals, but when they are put together, they make a diamond gem.

Diamonds are made from several different processes, which sometimes take a long time to become the gem that we know and love.

Learning intention: We are learning the structure of a explanation.
Success criteria: I know I can do this when I write the title, text and conclusion to my explanation and write about how diamonds were formed.
