In a series of fun and involving hands-on earth science experiments, kids learn how the sun's position affects how a rainbow is made, how stalagmites and stalactites are formed, how faults produce earthquakes, what happens when magma hardens inside a volcano, and how falling water weathers rocks. They will also determine and demonstrate how sound is used to find petroleum, how the continents separated, how a geyser works, and why streams are not always straight.--Amazon.
