Grade 4 Reading Comprehension Worksheet
Read the passage. Then answer each question.
WHY DOES THE OCEAN HAVE WAVES?
The ocean is never still. Whether observing from the beach or a boat, we
expect to see waves on the horizon. Waves are created by energy passing
through water, causing it to move in a circular motion. However, water does
not actually travel in waves. Waves transmit energy, not water, across the
ocean and if not obstructed by anything, they have the potential to travel
across an entire ocean basin.
Waves are most commonly caused by wind. Wind-driven waves, or surface
waves, are created by the friction between wind and surface water. As wind
blows across the surface of the ocean or a lake, the continual disturbance
creates a wave crest. These types of waves are found globally across the
open ocean and along the coast.
More potentially hazardous waves can be caused by severe weather, like a
hurricane. The strong winds and pressure from this type of severe storm
causes storm surge, a series of long waves that are created far from shore
in deeper water and intensify as they move closer to land. Other hazardous
waves can be caused by underwater disturbances that displace large
amounts of water quickly such as earthquakes, landslides, or volcanic
eruptions. These very long waves are called tsunamis. Storm surge and
tsunamis are not the types of waves you imagine crashing down on the
shore. These waves roll upon the shore like a massive sea level rise and
can reach far distances inland.

The gravitational pull of the sun and moon on the earth also causes waves.
These waves are tides or, in other words, tidal waves. It is a common
misconception that a tidal wave is also a tsunami. The cause of tsunamis
are not related to tide information at all but can occur in any tidal state.
