Quiz on Rocky Shore Zonation (Grade 9-10)

Why is the rocky shore ecosystem more productive than the sandy shore ecosystem?

• It has a warmer climate

• It has a greater variety and number of organisms

• It has lower levels of salt

• It is protected from wave action

What primarily prevents the deposition of sand along rocky shores?

• Low energy from waves

• High wave action

• Lack of vegetation

• Limited sunlight

What factor determines the zones of the rocky shore?

• The temperature of the water

• The type of rock

• The reach of the tide

• The amount of sunlight

Which zone is located furthest from the shoreline?

• Middle Intertidal Zone

• Lower Intertidal Zone

• Spray/Splash Zone

Which organisms are commonly found in the Spray/Splash Zone?

• Sea urchins and fish

• Periwinkles and hermit crabs

• Sea stars and anemones

• Algae and brittle stars

What is a key adaptation of organisms in the Upper Intertidal Zone?

• Ability to live in tide pools

• Ability to survive extensive dry periods

• Ability to stay submerged at all times

• Ability to withstand constant wave action

When is the Upper Intertidal Zone covered with water?

• Only at low tide

• Only at high tide

• Always covered with water

• Rarely covered with water

What is another name for the Middle Intertidal Zone?

Which of the following organisms would likely be found in the Middle Intertidal Zone?

• Sea stars and crabs

• Periwinkles and barnacles

• Giant anemones and sea urchins

• Only fish

Why are many organisms in the Middle Intertidal Zone found in tide pools?

• Tide pools provide a constant food supply

• Tide pools are a good source of fresh water

• Tide pools provide shelter and help retain water

• Tide pools are exposed to sunlight throughout the day
