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.
Answer:
A. y - 1 = -2(x - 4)
Explanation:
Recall that parallel lines have the same slope value.
Thus, the first step is to find the slope of the line given.
✔️Slope of the line that runs through (-3, 3) and (-2, 1):
slope (m) = change in y/change in x
Slope (m) = (1 - 3)/(-2 -(-3)) = -2/1
Slope (m) = -2
The slope (m) of the line that is parallel to the given line would also be -2.
✔️The slope of the line that is parallel to the given line which goes through the point (4, 1) can be written in point-slope form, y - b = m(x - a). Where,
(a, b) = (4, 1)
m = -2
Substitute the values into the equation
The equation of the parallel line would be:
y - 1 = -2(x - 4)

Answer:
"Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). ... The extreme astrophysical event of a supernova can produce enough energy to fuse nuclei into elements heavier than iron."
