Humans compared to Orangutans is an example of what kind of evolution? 1: Divergent Evolution
2: Convergent Evolution
3: Congruent Evolution
4: Digestive Evolution

I think in my opinion it's the Congruent Evolution

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
