What is the thickest interior layer of Earth? The thinnest?
Expert Solution & Answer
To determine
The thickest and the thinnest interior layer of earth.
Explanation of Solution
Introduction:
Measuring the thickness of different layers of the earth is possible as all layers have different properties. This is the reason due to which during earthquake waves travel with different velocities in each layer of the earth. When the wave enters another layer, then due to the change in the denseness of the medium, refraction of seismic wave takes place which makes it possible to know the thickness of the layer indirectly.
In general, the earth is known to have
The mantle is the layer next to the earth’s crust layer, and it covers approximately
Conclusion:
Therefore, Earth’s crust is the thinnest layer and mantle is the thickest one among all the layers.

Draw a third quadrant vector C. (remember that boldface characters represent vector
quantities). Show the standard angle 0 for this vector (= angle that C makes with the positive x-
axis). Also show the angle that C makes with the negative y-axis: call the latter angle 8. Finally,
show the smallest angles that C makes with the positive x-axis and the positive y-axis: call these
angles p1 and p2, repectively.
a) Prove the following formulas for the components of C involving the standard angle (hint:
start with the formulas for the components based on the angle & and then use (look up if
necessary) co-function identities linking cosine and sine of 8 to sine and cosine of 0 since 8 =
3π/2-8 (this will switch cosine and sine around and eliminate - signs as well))

- Notation matters when working with vectors! In particular, it is important to distinguish between the vector itself (A) and its magnitude (A). Illustrate in four separate sketches that each of the following statements is possible: a) both R = A + B and R=A+B are correct b) R = A + B is correct, but R=A+B is incorrect c) R = A + B is incorrect, but R=A+B is correct d) both R = A + B and R=A+B are incorrectarrow_forwardYou know from your math courses that an infinitesimal segment of a circular arc can be considered as a straight line segment.
