Question

1. when a wave passes a floating object, the object usually:

_____ a. moves all the way to shore
_____ b. sinks
_____ c. bobs up and down
_____ d. stops moving

1. which statement about currents is true?

_____ a. currents only move water near beaches
_____ b. currents move water in circles like waves
_____ c. currents act like rivers in the ocean
_____ d. currents only affect sea animals

Explanation:

For question 4: Ocean waves transfer energy, not mass, so a floating object only moves up and down with the wave's oscillation rather than traveling with the wave or sinking.
For question 5: Ocean currents are continuous, directed movements of seawater that function like large rivers within the ocean, moving water over long distances (not just near beaches, not in circles like waves, and they affect more than just sea animals).

Answer:

1. C. Bobs up and down
2. C. Currents act like rivers in the ocean
