Based on this final close-up, the fourth line points to the very center of the Earth, which is depicted as a solid yellow sphere. This is the innermost layer, known as the inner core. Therefore, for Q.1, the fourth blank should be labeled "Inner Core".
Now that I have identified all four layers for Question 1, I will move on to Question 2. The fill-in-the-blank questions require me to recall specific facts about these layers.
For Q.2a: "The thinnest layer of the Earth is the ________." Based on my analysis, the crust is the thinnest layer.
For Q.2b: "The thickest layer of Earth is the ________." The mantle is by far the thickest layer.
For Q.2c: "The ________ is composed of the melted metals of nickel and iron." This describes the outer core, which is liquid.
For Q.2d: "________ is rigid outer layer that include the upper part of the mantle and the crust." This refers to the lithosphere.
For Q.2e: "________ is plastic, flowing layer in the middle of mantle." This describes the asthenosphere.
I have now gathered all the information needed to complete both questions. I will now provide the final answer.
Solution
Q.1. Label the layers of the Earth.
Based on the cross-section diagram, the layers from the outside in are:
1.
Crust (the thin, brownish outermost layer)
2.
Mantle (the thick, red-orange layer beneath the crust)
3.
Outer Core (the orange layer between the mantle and the inner core)
4.
Inner Core (the innermost, yellow sphere)
Q.2. Fill in the blanks with suitable words.
a) The thinnest layer of the Earth is the
Crust.
b) The thickest layer of Earth is the
Mantle.
c) The
Outer Core is composed of the melted metals of nickel and iron.
d)
Lithosphere is rigid outer layer that include the upper part of the mantle and the crust.
e)
Asthenosphere is plastic, flowing layer in the middle of mantle.
