Deep beneath the Cascade Mountains in the Northwest,where molten magma heats the earth's crust and occasionally bursts through cracks and fractures in violent volcanic eruptions,lurk an energy source that scientists think could be tamed to help power the region.

這句子我沒辦法把他的主詞動詞清楚的分開
裡面有三個and也讓我不知道是誰連接誰
請英文高手幫我分析
如果可以順便教教我遇到長長的句子時應該怎樣分析
個別是閱讀跟聽力部分(聽力我聽到很長的句子根本陣亡)

先謝謝各位高手^^
