Question

question: a scientist collects a magma sample that took hundreds of years to cool into rock. which mineral crystals are most likely to be found within the rock? answer options: select one of four crystals wont form. irregular structures large fine-grained

Explanation:

When magma cools slowly (over hundreds of years), mineral crystals have more time to grow. Slow cooling allows atoms to arrange into larger, well - formed crystal structures. Fast cooling leads to fine - grained or glassy (non - crystalline in some cases) rocks. Since this magma took hundreds of years to cool, the crystals formed should be large. "Crystals won't form" is incorrect as slow cooling promotes crystallization. "Irregular structures" is not typical of slow - cooled magma crystals. "Fine - grained" is associated with rapid cooling.

Answer:

Large
