The Deep Dive
Drilled core samples are like the treasure maps of oceanographers! These samples reveal the age of the ocean floor, showing that newer, younger rock is found closer to the mid-ocean ridges, while older rock sits farther away. This age difference is a key sign of seafloor spreading, providing concrete evidence of how tectonic plates move apart.
Fossil material can be quite the detective in this scenario too! By studying fossil distributions found on either side of the ocean, scientists have discovered similar species, indicating that these landmasses were once connected before drifting apart. It’s like piecing together a giant jigsaw puzzle of Earth’s past!
