Answer 1

1. The best definition of the word "cycle" from the given options is:

D - A series of events that occur over and over in a specific order.

2. The reason this image can’t be considered a cycle is:

C - This is a one-time transformation that does not repeat.

3. From the information that Earth’s rocks go through a cycle, we can conclude:

B - Rocks are constantly transformed and recycled.

4. Without the specific diagram shown, I can't identify the correct layer that represents Earth's crust. Typically, the Earth's crust is the outermost layer, so if you have the diagram, the correct answer would likely be the layer depicted as the thinnest and on top. Please provide more information or the diagram for a definitive answer.
