Which of the following describes how Marie Tharp and Bruce Heezen found evidence that led to the theory of plate tectonics? (1 point) Responses They mapped the structures on the ocean floor using sonar rays to collect data. They mapped the structures on the ocean floor using sonar rays to collect data. They observed two tectonic plates moving away from each other. They observed two tectonic plates moving away from each other. They observed that the continents seem to fit together like a puzzle. They observed that the continents seem to fit together like a puzzle. They mapped the structures on the ocean floor using a video recording to collect data. They mapped the structures on the ocean floor using a video recording to collect data.
They mapped the structures on the ocean floor using sonar rays to collect data.
1. Mid-ocean ridges
2. Rift valleys
1. Ridges
2. Volcanoes
Due to subduction, magma shoots out of the crust.
Transform boundary
Yes, all of the given answers are correct:
1. They mapped the structures on the ocean floor using sonar rays to collect data.
This describes how Marie Tharp and Bruce Heezen found evidence that led to the theory of plate tectonics.
2. Volcanoes, Ridges
These are the correct types of structures that form at divergent boundaries.
3. Due to subduction, magma shoots out of the crust.
This explains why volcanoes can form at convergent boundaries.
4. Transform boundary
This is the type of boundary described where two plates slide past each other, causing the crust to start falling apart and forming cracks.
