It deposited 5-30 km of crustal material on the far side forming highlands.
New crustal material will well up from below.
Density differences in crustal material largely arise from different ratios of various elements, especially silicon.
They also include older crustal material from the Tanzanian craton that has been reworked.
According to them, the mountain is one block of crustal material, due to its polygonal, relatively intact shape.
This old volcanic crustal material is compressed laterally as it sinks.
Until now, scientists have considered two main possible fates for the submerged crustal material.
Most achondrites are also ancient rocks, and are thought to represent crustal material of asteroids.
Additionally, continental crustal material is transferred to oceanic crust by sedimentation.
It was slow hard work, for the fibers were the source of the real strength of the crustal material.
