Cycles in Nature

Water is essential for life, but where does it come from? This exciting book dives into that question to explain to readers exactly what happens in the water cycle. From underground springs that feed rivers and lakes to ocean water, it all helps create the clouds that move water particles from place to place. The way water moves around changes the landscape, temperature, and climate all around the world, and readers learn how this much-needed cycle impacts their lives every day.

Heat and energy impacts all life on our planet. Energy from the sun helps plants grow and makes it possible for us to live on Earth at all, but the heat from inside Earth impacts us as well. There are many different kinds of rocks that make up Earth's crust, and scientists now know how Earth's energy forms and changes these rocks. Readers will learn about the volcanoes and lava that make igneous rocks, and how heating and cooling caused by energy in Earth's core creates metamorphic rocks. They'll also learn how water and other elements break down rocks to create sedimentary rocks and various rock formations all over the world.

For many years people wondered why the moon seemed to change shape. Now we know that the moon isn't changing, but rather what we can see of it is constantly changing. It, too, follows a pattern we see over and over again from month to month. Readers will love learning about the eight phases of the moon and why, even though the sun always lights the moon, we can't always see it!

Enjoying the view of a field of flowers on a nice day is delightful, but knowing how those beautiful flowers got there is even more interesting.
