Our names are Arula and Ainoa, and we are going to talk about gypsum.
00:00:00
Gypsum form deep underwater when creatures like gums, oysters, scallops, and surf fish die.
00:00:06
They remain into the ocean flooring layer.
00:00:20
Over time, hundreds of layers push down on the top of the original layer.
00:00:26
This causes it to be turned into rock.
00:00:37
Some of this rock contains gypsum.
00:00:41
Gypsum is a very soft material.
00:00:44
It can be scratched with your fingernail.
00:00:47
We use gypsum used to make medical gauze.
00:00:50
They put this on you when you break a bone.
