Explanation:

• For "There was a powerful earthquake in Alaska" as the cause, the effect is "Fishing boats sank in Louisiana" because the text mentions the 1964 Alaska earthquake was so strong its effects were felt far away (thousands of miles) and fishing boats in Louisiana sank.
• For "A plate scrapes or bumps another plate" as the cause, the effect is "Earthquakes happen" since the text states that when plates collide or rub against each other (which is like scraping or bumping), it leads to earthquakes.
• For "Most earthquakes happen deep below the surface" as the cause, the effect is "People don't feel most earthquakes" as the text says that when quakes happen deep inside the earth (up to four hundred miles below the surface), they are never felt.

Answer:

• Cause: There was a powerful earthquake in Alaska. Effect: Fishing boats sank in Louisiana.
• Cause: A plate scrapes or bumps another plate. Effect: Earthquakes happen.
• Cause: Most earthquakes happen deep below the surface. Effect: People don't feel most earthquakes.
