Crack the Puzzle: Soil vs. Skin

Hello Everyone, 

    Last week, I went for a walk with my mom and noticed these cracks in the soil.  

    I was curious about the cracks and decided to see what was under it.

    Did you see that?? There is an another layer of soil under the dried layer. This reminded me of cracked skin! When I thought about it, I was really surprised to know how earth and skin are similar in nature.

Look at these pictures:

    What did you notice? I noticed that both earth and skin have layers! I also noticed that the top layers show cracks when the water dries up! Maybe, that causes the top layer to separate from the other layers. Soil has 4 layers and the skin has 3 layers. Now, look at this picture of tree trunk:

Isn't it surprising?? The tree trunk also has texture like cracks, that is for a different reason though. 

Conclusion: Nature surprises me often and water is an essential element in it. Life can’t exist without water. Please share your comments.
