During a powerful storm in 1990, what appeared on the beaches of Oregon, Hawaii, and Japan?

• Plastic bottles

• Marine animals

• Shoes

• Driftwood

How did the shoes mentioned in the text end up on the beaches of Oregon, Hawaii, and Japan?

• They were lost by beach visitors

• They were discarded from nearby cities

• They fell off a cargo ship during a storm

• They were intentionally thrown into the ocean

What is the main idea presented in the text about the ocean?

• The ocean is a static body of water

• The movement of the ocean carries energy and objects wherever it goes

• The ocean is not as big as it appears in photographs

• The ocean is primarily a source of food

What is the relationship between the distance from the equator and the amount of energy transferred from the sun to the ocean surface?

• The closer to the equator, the more energy is transferred.

• The farther from the equator, the more energy is transferred.

• The distance from the equator does not affect the energy transfer.

• The energy transfer is greater at the poles.
