Question

5.which sentence from the passage best shows cause and effect?
a. “volcanoes can form on land or under the ocean.”
b. “the ash and lava break down and mix with soil, making it rich with nutrients.”
c. “scien use special tools to study volcanoes.”
d. “som canoes are tall and shaped like cones.”

Explanation:

A cause - and - effect relationship shows that one event (the cause) leads to another event (the effect). In option B, "The ash and lava break down and mix with soil" is the cause, and "making it rich with nutrients" is the effect. Option A just states a fact about where volcanoes can form. Option C is about what scientists do. Option D is about the shape of some volcanoes. None of these options show a clear cause - and - effect like option B.

Answer:

B. "The ash and lava break down and mix with soil, making it rich with nutrients."
