Question

select the correct text in the passage. which statements in this passage about volcanoes do not contain factual errors? the hawaiian islands are known for their volcanic activities. in fact, the islands were formed from volcanoes. before a volcano erupts, earthquake activity beneath the volcano decreases. scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. they then predict the eruption of that volcano. when a volcano erupts, the amount of carbon dioxide and sulfur dioxide emitted decreases. scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir

Explanation:

The Hawaiian islands were indeed formed from volcanoes. Seismometers are used to measure earthquake activity beneath a volcano to predict eruptions. These are factual statements. The statement that earthquake activity beneath a volcano decreases before an eruption is incorrect as it usually increases. Also, the amount of carbon - dioxide and sulfur - dioxide emitted increases during a volcanic eruption, not decreases.

Answer:

The Hawaiian islands are known for their volcanic activities. In fact, the islands were formed from volcanoes. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.
