The tone which is the author's attitude toward the characters or audience in Earth On Turtle's back is encouraging because all of the animals are hoping that one of them will reach the bottom and find earth. The mood which is the emotional state of the reader is happy because we are happy once we find out that the muskrat reaches the surface with earth in her hands. Another mood can be melancholy because all of the strongest animals fail and the smallest animal says he will go or die trying.
