  2. Do you agree with the statement? 1 Earth is made up of several layers. Yes No

  3. Do you agree with the statement? 2 The crust is the outermost layer of Earth. Yes No

  4. Do you agree with the statement? 3 Temperatures are generally higher in the mantle than in the core. Yes No

  5. Do you agree with the statement? 4 Scientists are able to go into the mantle and core to learn about them. Yes No

  6. The Crust The crust is the outside layer of the Earth and is also the thinnest layer. There are two kinds of crust: continental crust and oceanic crust. Continental crust makes up the lands of the continents. Oceanic crust lies below most of the ocean floor. Continental crust and 
oceanic crust meet underwater.

  7. The Mantle and Core The mantleis below the crust and is the thickest layer of Earth. The top of the mantle is made of partially melted rock. The crust and the top of the mantle make up the lithosphere, which 
covers Earth like a thin shell. The deeper part of the mantle is made of solid rock and is under 
very high pressure with temperatures ranging from 900°C to 2,200°C. Slow convection currents move the rock in the mantle. Cooler rock 
flows down and hotter rock flows up. The coreis at the center of Earth and is made mostly of iron, with 
temperatures about 5,000°C. The inner core is solid and the outer core is liquid. This liquid moves in currents, which make Earth’s magnetic field. Earth's Structure
