The theory of plate tectonics was developed with the contribution of scientists from many different disciplines. what contribution of geophysicists contributed to our understanding of deep-sea ridges and plate tectonics?

a. deep-sea ridges show that life could have evolved along the boundaries of tectonic plates.
b. detritus from dead marine animals on the ocean floor shows that new tectonic plates are constantly being formed.
c. earth's magnetic fields captured in the rock around deep-sea ridges show that fresh magma emerges between tectonic plates.
d. mountain ranges on the ocean floor show that tectonic plates can rise and sink over several hundred million years.
