Answer: C) extremely rapid cooling
Explanation:
When magma goes through extremely rapid cooling and especially if it did not dissolve enough water into it, it could freeze to glass or the mineral crystals that will be formed will be so small, they will look like glass.
This is because the reactions that occur to create minerals are affected directly by temperature such that if the magma cools down extremely slowly, it will form very large crystals but extremely fast would result in small crystals.
Well for starters they could use harnesses to protect them if they fell
• temperature
• warm-up-time
• cooling time
• regulation stability
I believe an answer could be assimilation, as assimilation is the integration or process of people/ideas/culture into a bigger culture or society. It was one of the major results of immigration into the United States.
I hope this helps :)
I will definitely feel bad about what happen, try to help if i can by doing fundraising's, going to the family of the included people and donate things for their mental stage. <span />
