In Journey to the Center of the Earth, by Jules Verne, an adventurer travels through the layers of Earth until he reaches the center. While it is not possible actually to travel through all of the layers of Earth, in what order would the adventurer have traveled to reach the center? Rearrange the layers into the correct order. Place the outer layer at the top and the innermost layer at the bottom.

Temperature and pressure change as a space shuttle blasts off and travels away from Earth’s surface. Temperature and pressure also change as a diver sinks deep beneath the surface of the ocean. How do temperature and pressure change as you travel through the layers beneath the surface of Earth? The closer you get to Earth's core, the temperature ___________ and the pressure increases.
