ES-4.8-Testing-the-Plate-Tectonics-Model

The islands are all the same age.

The chain shows a clear age progression from youngest to oldest islands.

The islands are randomly distributed.

The islands are formed by continental drift.

Magnetite grains act like compass needles

Record magnetic pole positions at formation time

Provide evidence of continental drift

Create new oceanic crust

It revealed seafloor age patterns through ocean sediment drilling.

It discovered new continents under the ocean.

It proved that volcanoes do not affect tectonic plates.

It found that the ocean floor is older than the continents.

It helped confirm the theory of plate tectonics and revolutionized our understanding of Earth's processes.

It only provided information about ocean life.

It disproved the existence of tectonic plates.

It was mainly used for navigation purposes.
