When molten rock undergoes crytalization above ground what happens.?

it cools much faster on land than in the earth. is makes smaller crytals

when lava cools, small crystals form and sometimes co2 gets trapped and makes air bubbles in the rock. they burst and thats what creats the vesticular aperience

sorry, grammer and spelling is hard :(

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
