From way up high, our planet looks like a floating marble of blue, white, and green. But we know that it's so much more. Earth has giant oceans and tiny ponds, towering mountains and rolling hilltops, warm sunshine, fluffy snowflakes, stormy showers, and falling autumn leaves. There are other planets as well with many interesting characteristics.

Imagine a herd of elephants all talking to each other. How do they do it? What do they tell each other? Readers will learn a lot about elephants, habitats, animal communication, and much more. With their curiosity piqued, readers then zigzag to other questions: what if elephants lived in a different environment? How do other creatures communicate?
