The correct answer is: Younger rocks are warmer and are located closer to mid-ocean ridges.
The correct answer is: Younger rocks are warmer and are located closer to mid-ocean ridges.
This pattern can be explained by the process of seafloor spreading. When new oceanic crust forms at mid-ocean ridges, it is initially hotter than the older surrounding rocks. As the crust moves away from the ridge, it cools down over time. This means that the younger rocks near the mid-ocean ridges are warmer compared to the older rocks further away.
To determine this pattern, scientists study core samples taken from the ocean floor. These samples are obtained by drilling into the seafloor and extracting cylindrical samples of rock layers. By analyzing the composition and age of these rocks, scientists can determine their location relative to mid-ocean ridges and subduction zones, as well as their temperature at the time of formation.
