Intertidal Zone Quiz: Trivia!

1.

What types of wetlands occur around an intertidal zone?
- A.
  
  Estuary
- B.
  
  Salt marsh
- C.
  
  Bogs
- D.
  
  None of the above
Correct Answer
B. Salt marsh

Explanation
Salt marshes are a type of wetland that occur around intertidal zones. They are characterized by the presence of salt-tolerant plants and are typically found in coastal areas where there is a mix of saltwater from the ocean and freshwater from rivers or streams. Salt marshes provide important habitat for a variety of species, including birds, fish, and invertebrates. They also act as a buffer against coastal erosion and help to filter pollutants from the water.

You would be most likely to find a mangrove swamp along the shores of:
- A.
  
  Florida
- B.
  
  Southern Argentina
- C.
  
  The Great Lakes
- D.
  
  Japan
Correct Answer
A. Florida

Explanation
Mangrove swamps are coastal wetlands characterized by the presence of mangrove trees. These trees thrive in warm, tropical and subtropical regions with high humidity and saltwater. Florida, being a peninsula surrounded by the Atlantic Ocean and the Gulf of Mexico, has a suitable climate and coastal environment for mangrove swamps to flourish. On the other hand, southern Argentina does not have the same warm climate and is not known for its mangrove swamps. The Great Lakes are freshwater bodies and do not provide the necessary conditions for mangroves to grow. Japan, although having a coastal geography, does not have a significant presence of mangrove swamps compared to Florida.

What is the distance range for the intertidal zone?
- A.
  
  From the low tidemark to the continental shelf
- B.
  
  From the continental shelf to open ocean
- C.
  
  From the high tidemark to open ocean
- D.
  
  From the high tidemark to the low tidemark along shore
Correct Answer
D. From the high tidemark to the low tidemark along shore

Explanation
The intertidal zone refers to the area between the high tidemark and the low tidemark along the shore. This zone is exposed to both air and water as the tides rise and fall, creating a unique and challenging habitat for organisms. Therefore, the correct answer is "From the high tidemark to the low tidemark along shore."

Complete the following analogy:Mangrove swamp:Tropical water as ________:_______
- A.
  
  Kelp reef:Temperate water
- B.
  
  Salt marsh:Temperate water
- C.
  
  Estuary:Fresh water
- D.
  
  Rainforest:Land biome
Correct Answer
B. Salt marsh:Temperate water

Explanation
The analogy in the given question is comparing different ecosystems and the type of water they are associated with. A mangrove swamp is a type of ecosystem found in tropical water, so the correct answer would be an ecosystem found in temperate water. The analogy suggests that a salt marsh is the equivalent ecosystem found in temperate water.

The intertidal zone is one of the three _________ divisions of the ocean.
- A.
  
  Vertical
- B.
  
  Closer
- C.
  
  Horizontal
- D.
  
  Newest
Correct Answer
C. Horizontal

Explanation
The intertidal zone is one of the three horizontal divisions of the ocean. This zone is the area between the high tide and low tide marks, where the ocean meets the land. It is characterized by the constant exposure to both air and water, resulting in unique ecological conditions. The other two divisions of the ocean, the pelagic zone and the benthic zone, are not specifically tied to the shoreline and are therefore not considered as horizontal divisions.

Why are salt marshes so important to the environment?
- A.
  
  They are a home for many underwater plants and animals.
- B.
  
  Migratory birds use them as a feeding ground.
- C.
  
  Many commercial fish species breed in them.
- D.
  
  Both A and C.
- E.
  
  Both B and C.
Correct Answer
E. Both B and C.

Explanation
Salt marshes are important to the environment because they serve as a feeding ground for migratory birds and also act as a breeding ground for many commercial fish species. Both of these factors contribute to the overall biodiversity and ecological balance of the ecosystem.

Which of the following is a true statement about mangrove swamps?
- A.
  
  Mangrove swamps can survive in cold temperatures.
- B.
  
  Mangrove trees can survive in water with low oxygen levels.
- C.
  
  Mangrove tree roots are completely under water.
- D.
  
  Mangrove swamps are in no danger due to human destruction of the swamps.
Correct Answer
B. Mangrove trees can survive in water with low oxygen levels.

Explanation
Mangrove trees have adapted to survive in environments with low oxygen levels by developing specialized root systems called pneumatophores. These structures allow the trees to obtain oxygen from the air and transport it to their roots, enabling them to thrive in waterlogged and anaerobic conditions. This adaptation is essential for their survival in mangrove swamps, where oxygen levels in the water can be significantly lower than in other ecosystems.

What ecosystem is shown in the picture below?
- A.
  
  Mangrove swamp
- B.
  
  Estuary
- C.
  
  Coral reef
- D.
  
  Salt marsh
Correct Answer
D. Salt marsh

Explanation
The correct answer is salt marsh. A salt marsh is a coastal ecosystem that is characterized by grasses, sedges, and other salt-tolerant plants. It is typically found in areas where freshwater and saltwater mix, such as estuaries. The picture likely shows a flat, marshy landscape with vegetation that can withstand high salt concentrations.

How many times a day does the high tide and low tide come in or out respectively?
- A.
  
  Once
- B.
  
  Twice
- C.
  
  Three times
- D.
  
  Four times
Correct Answer
B. Twice

Explanation
The high tide and low tide each occur twice a day. This is due to the gravitational pull of the moon and the sun on the Earth's oceans. As the Earth rotates, different parts of the ocean experience the gravitational force, causing the water level to rise (high tide) and fall (low tide) approximately every 12 hours. Therefore, there are two high tides and two low tides in a 24-hour period.

Why would it be advantageous to burrow oneself into the sand if you lived in an intertidal zone?
- A.
  
  So you would not be carried away by the tides
- B.
  
  So you could make a bigger home
- C.
  
  So you could get more oxygen
- D.
  
  It would not be advantageous to burrow into the sand.
Correct Answer
A. So you would not be carried away by the tides

Explanation
Burrowing oneself into the sand in an intertidal zone would be advantageous because it would prevent being carried away by the tides. The intertidal zone experiences regular tidal movements, with water levels rising and falling. By burrowing into the sand, an organism can anchor itself and avoid being swept away by the strong currents. This allows for stability and protection from being washed away, ensuring survival in this dynamic environment.
