Ocean Floor Mapping Experiment

The video tutorial introduces Lab 4, focusing on mapping the ocean floor using sonar technology. It explains the historical context of sonar use during WWII and its role in developing the theory of seafloor spreading. The tutorial provides detailed instructions on setting up lab equipment, conducting the experiment, and analyzing data. It emphasizes comparing motion detector data with measured data for accuracy. The second part of the experiment involves using two boxes to simulate different ocean floor features.

What technology is used in Lab 4 to map the ocean floor?

• GPS

• Lidar

• Sonar

• Radar

What historical event led to extensive mapping of the ocean floor using sonar?

• The Space Race

• The Cold War

• World War II

• World War I

Which device is essential for collecting data in this lab?

• LabQuest

• Thermometer

• Barometer

• Spectrometer

What should you use to secure the motion detector during the experiment?

• Glue

• Nails

• Rubber bands

• Masking tape

In Part 1 of the experiment, what is the purpose of the box placed on the floor?

• To balance the equipment

• To simulate an ocean floor feature

• To act as a weight

• To measure temperature

What is the recommended sample rate for the LabQuest during data collection?

• 15 samples per second

• 10 samples per second

• 20 samples per second

• 5 samples per second

What should you use to measure the height of the box in the experiment?

• A meter stick

• A ruler

• A protractor

• A caliper

How should the height of the table be recorded?

• In yards

• In inches

• In meters

• In feet

In Part 2 of the experiment, how should the boxes be arranged?

• Randomly placed
