4. a measurement of distance needed to travel through an object or material

2. the melted/liquid layer just outside the center of the Earth
3. a liquified layer at the top of the mantle that allows the layers above it to move
7. the solid layer at the center of the Earth - despite having the highest temperature, intense pressure keeps it solid
10. a measurement of how tightly something is packed into a particular area
