Which two phrases in the passage demonstrate what the word boisterous means?
Close by, a rock of less enormous height
Breaks the wild waves, and forms dangerous strait;
Full on its crown a fig's green branches rise,
And shoot a leafy forest to the skies;
Beneath, Charybdis holds her boisterous reign
'Midst roaring whirlpools, and absorbs the main;
Thrice in her gulfs the boiling seas subside,
Thrice in dire thunders she refunds the tide.
