Listening to Ocean Plate Boundaries

Lucas is working on a school project about oceanography. He decides to focus on a unique aspect of the ocean. What is the primary focus of Bob Dziak's research that he could explore?

• Studying ocean currents

• Listening to plate boundaries

• Observing marine life

• Measuring ocean temperature

During a school project, Isaac and Mila were researching about different organizations. They came across Bob Dziak and wanted to know which organization he works for. Can you help them find out?

• NASA

• NOAA

• EPA

• USGS

How deep did Nala's team send the hydrophones into the ocean?

• 5.5 kilometers

• 8.2 kilometers

• 10.99 kilometers

• 12.5 kilometers

During a school project, Lucas and Nala were tasked with researching the deepest place in the ocean where hydrophones were sent. What is the name of this location?

• Mariana Trench

• Challenger Deep

• Puerto Rico Trench

• Tonga Trench

Why is it difficult for Zavier and Leyla to explore the deepest parts of the ocean?

• Lack of interest

• High pressure and extreme conditions

• No available technology

• It's too shallow

During a school project, Miah and her team wanted to study the ocean floor. What tool did they use?

• Sonar

• Hydrophones

• Submarines

• Satellites

Miah and Zavier are marine biologists studying the sounds at the ocean floor. Explain why hydrophones are suitable for their research.

• They are lightweight and easy to deploy

• They can withstand high pressure and capture underwater sounds

• They are inexpensive

• They are used for navigation

What unexpected finding did Mila and her team discover with the hydrophones?

• No sounds were detected

• Sounds from many different sources were detected

• Only marine life sounds were detected

• Only geological sounds were detected

Discuss the potential reasons why Yusuf and his team might have been surprised by the amount of noise detected at such depths.

• They expected the ocean floor to be silent due to isolation

• They thought the equipment would fail

• They believed marine life was absent at such depths

• They assumed the water would block all sounds

Leyla and Isaac are part of a research team studying sounds at plate boundaries. What is the significance of their research?

• To improve fishing techniques

• To understand geological activities and potential hazards

• To enhance underwater tourism

• To map ocean currents
