Answer:
A.
Explanation:
Earth is composed of different layers and one layer moves over another due to differences in the densities.
According to the physics of density, a substance having less density floats over a higher density substance. The oceanic crust has more density than the continental crust that is why continental crust float over oceanic crust.
So in the given example, plate B is moving below the plate A, it means plate B is more dense than plate A because plate B is composed of oceanic crust
. <u>For example : continents float over the asthenosphere (a layer below the lithosphere).</u>
Hence, the correct answer is "A
".
Answer:
They are both wrong!
Liquid oxygen really is a pale blue color.
I’ve seen it.
And they cant say that liquid and solid oxygen is blue which makes the sky blue because they’re not and it doesn’t make up for the color of the sky.
The sky is actually blue because It reflects more light than It can absorb
aka Rayleigh Scattering.

The linear scale is applicable only as it moves in one dimension. From the word "linear" it means it deals with one equation only. Unlike the other options, the dimensions are many because it involves 2 or more variables for its equation.
<span>Surface ocean currents are generally wind-driven. However, the rotation of the Earth affects the way the waters move through currents. Without rotation, currents may not exist.</span>
The object rises to a height of 20.4 m. So option C is correct.
Explanation:
initial velocity= Vi=20 m/s
final velocity at the top= Vf=0
acceleration= g=-9.8 m/s²
Vf²=Vi²+2gh
0= (20)²+2 (-9.8)h
-200=-9.8h
h=200/9.8
h=20.4 m
Thus the object rises to a height of 20.4 m
