Answer:
Question 1 answer
Plate tectonic began in 1915 when Alfred Wegener proposed his theory which was continental drift. Usually scientists use waves to study the difference of the layers of earth. They use seismic waves. seismic waves are generated by earthquakes or nuclear-test explosions.
Those 3 pieces would be the fit of the continents, paleoclimate indicators, and geologic features. The rock formations of eastern North America, Northwestern Africa and Western Europe were found later to have a common origin. They were found to overlap.
Question 2 answer

Explanation: I just took the test. Trust me!!!
Data collected by the drilling ship Glomar Challenger confirmed that C. NONE OF THE OCEAN FLOOR IS MORE THAN 180 MILLION YEARS OLD.
Glomar Challenger began drilling on both sides of the mid-ocean ridges to gather data. The data confirmed what the sea-floor spreading hypothesis predicted. The ocean floor is youngest along the central valley of the mid-ocean ridge while the ocean floor in subduction zones or near the edges of the continents is oldest. The data has confirmed that none of the ocean floor is more than 180 million years old because the older oceanic rock will undergo subduction and go back to the earht's mantle.
I would go with B & D because they change over time and they can go extinct like those big octopus in the oceans, they are rare to see in my opinion because they can blend in with other things that keeps them away from danger.
