1. Which sequence best describes the process that leads to many earthquakes?

Plates move → friction builds energy → energy is released → the ground shakes
Clouds form → rain falls → earthquakes begin
Plates stop moving → energy disappears → the ground stays still
Oceans warm → tides increase → earthquakes happen

2. Where do many earthquakes happen most often, according to the video?

Only near rivers
In the middle of continents far from any plate edge
Only in very cold places
Along active plate boundaries

3. What is one reason earthquake experts watch earthquake activity near volcanoes?

It guarantees there will be no eruption
It makes weather forecasts more accurate
It can suggest magma is pushing upward and an eruption may be coming
It changes animals' behavior permanently
