Paperback
(Gareth Stevens Pub, July 15, 2015)
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 Earths crust, and scientists now know how Earths 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 Earths core creates metamorphic rocks. Theyll also learn how water and other elements break down rocks to create sedimentary rocks and various rock formations all over the world.
