About this worksheet
This check for 5th grade science fits on one page. A colored cross-section of Earth carries four numbered pointer lines, and students write the crust, mantle, outer core and inner core from a word bank. Below it they complete two sentences about the liquid layer and the thickest layer, put the four layers in order from hottest to coolest and write how scientists learn about layers that nobody has drilled to. Page 2 holds the answers, with sample wording about seismic waves.
