Question

read the passage. then answer the question.
earth has an outer layer of rocks, or plates. these plates float
on molten rock, which is in constant motion. first, the
warmest material rises. then, it cools and sinks. finally, it
warms and rises again.
its because of this motion that the plates move in different
ways. they slide toward each other, away from each other, or
across each other. however, all three movements are similar
in that they can transform the landscape. mountains,
volcanoes, and ocean trenches are formed from moving
plates.

Explanation:

• Paragraph 1: The paragraph uses sequence words like "First", "Then", "Finally" to describe the movement of molten rock. This is characteristic of a chronological text structure which presents events in the order they occur.
• Paragraph 2: It explains that the motion of molten rock (cause) leads to the movement of plates in different ways and the formation of landscape features (effect). This is a cause - and - effect text structure.

Answer:

Paragraph 1: chronological
Paragraph 2: cause and effect
