Use sources to show that some Earth events occur quickly Practice Test

Which photo shows an Earth event that would happen quickly (in days or weeks)?

Pompeii is an ancient city in Italy. It was a very popular and busy city. There were restaurants, shops, farms, and lots of people. That changed in the year 79 A.D. A nearby volcano called Mount Vesuvius erupted. When it exploded, it threw ash and rock into the air for two days. Tons of ash covered Pompeii. The city was covered in twenty-three feet of debris. Thousands of people died. No one was expecting the volcano to erupt. Even with technology, today, scientists cannot accurately predict when a volcano will erupt. Residents near the volcano do not get much of a warning to escape the danger.

Why did the residents not leave the area, so they were safe?
