LIDAR stands for Light Detection and Ranging. LIDAR sends laser light from the bottom of an airplane to the sea floor.
The light reflects back to the airplane.
LIDAR measures the time it takes for the reflections to return to the airplane.
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
The scientists realized that the continents were much older, leading them onto the theory of Sea Floor Spreading!
the scientist was Dr. alfred wegener.
The climate at the time the fossile was preserved. :)
The sea floor, under water mountains, sea life, under water lava flows, etc.
Scientists found Alternating bands of magnetism.
Determining how the sea floor changes over time has given scientists information about the Earth's tectonic plate movements, the distribution of volcanic activity, and the history of sea level changes. Observing these changes helps scientists better understand the dynamic processes that shape our planet.
