Earth’s Crust Elements
The crust is a rigid surface containing both the oceans and landmasses. Most elements are found in only trace amounts within the Earth’s crust, but several are abundant.

This rover has moves that could take over a dance floor. A new video shows a simulator known as the Ground Test Model doing a sort of zombie walk over Martian-like terrain, to test out techniques for a future Mars missions.
“The rover initially has its front two wheels almost completely buried in sand, but easily escapes using its unique wheel-walking mode,” the European Space Agency said in a statement of the testing at Thales Alenia Space facilities in Turin, Italy, noting that the 6-foot drive took about 20 minutes to accomplish.
“The back wheels drag once the front four wheels have gained good traction on firmer terrain. The reason is that the wheel-walking sequence tested here has rather been optimized for climbing steep slopes with loose soils,” ESA added of the sequence.
