how does volcanoes change over time?

At the very beginning,the side part of the volcano becomes bigger and bigger because of the pressure comes from the lower part of it,finally,it erupts and the magma flows downhill,the dust is blowed into the sky,usually it can reach the troposphere,spread all over the world and have some impact on the global climate.Eventually,the volcano calms down and fall asleep again waitting for the other summon of the earth.I wish it can help you out.

火山喷发（volcanic eruption）
火山喷发是岩浆等喷出物在短时间内从火山口向地表的释放。由于岩浆中含大量挥发分，加之上覆岩层的围压，使这些挥发分溶解在岩浆中无法逸出，当岩浆上升靠近地表时，压力减小，挥发分急剧被释放出来，于是形成火山喷发。火山喷发是一种奇特的地质现象，是地壳运动的一种表现形式，也是地球内部热能在地表的一种最强烈的显示。
因岩浆性质...

随着时间的推移，火山是怎么变化的？
或者
火山是怎么随着时间的推移而变化的？
over time(短语) 解释:随着时间的推移

直译是火山是如何转换时间的？
意思可能是火山的周期如何？
