GIS and Seafloor Spreading Concepts

The video tutorial explores the principle of seafloor age in plate tectonics using GIS. It guides viewers through collecting data from various locations, analyzing it, and presenting findings through graphs. The tutorial emphasizes the symmetrical pattern of seafloor spreading and provides step-by-step instructions for data collection and analysis.

What principle related to plate tectonics is explored in this task?

• The movement of tectonic plates

• The formation of mountains

• The age of the seafloor

• The occurrence of earthquakes

What is the main purpose of using GIS in this task?

• To create maps

• To test the theory of seafloor spreading

• To measure land elevation

• To track weather patterns
