Available in PDF, EPUB and Kindle. Book excerpt: 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.
