Answer:
C. The greater an element's density, the smaller the amount of it found in the crust
Explanation:
The layering of the Earth happened because of the different densities of the elements from which it was made. The denser elements started to sink deeper, the elements with medium density occupied the central part, and the elements with the smallest density remained at the surface. This resulted in the formation of the three basic layers of the Earth, core, mantle and crust. The core is composed of the densest elements, the mantle of the ones with medium density, and the crust from the ones with smallest density.
C. Because the pink rectangle is a plane like a piece of flat paper, and you look at the points that are sitting on the plane which are points C and E
The answer is obviously 64.
Answer:
Human evolution is characterized by speciation, extinction and dispersal events that have been linked to both global and/or regional palaeoclimate records [1–7]. Many theories have been proposed to link environmental changes to these human evolution events [8–11].
