Question

read the sentence.
after weeks of frequent tremors, the earths crust opened, and lava escaped from below the surface.
now, revise the sentence to show that the earths crust opened suddenly and with force.
after weeks of frequent tremors, the earths crust ______, and lava escaped from below the surface.
unfolded cracked ruptured yielded

Explanation:

To show the Earth's crust opened suddenly and with force, we analyze the options:

• "unfolded" means to open out from a folded state, not related to a forceful opening of the crust.
• "cracked" implies a break but may not convey the sudden and forceful nature as strongly as "ruptured".
• "ruptured" means to break or burst suddenly and violently, which fits the requirement of sudden and forceful opening.
• "yielded" means to give way or surrender, not the same as a forceful opening.

Answer:

ruptured
