Inside Earth

1. Made up of hot solid rock that moves throughout the layer
3. Type of seismic wave that moves the fastest and can move through liquids
8. Plate boundary where plates slip past each other and move in opposite directions
9. Earth's crust and upper mantle form this
11. Traces of organisms that can be used to show that continents have moved over time
13. Flow of liquids and gases that occurs when they are heated and cool off
14. Part of the core made of solid iron and nickel
16. Type of seismic waves that vibrate from side to side
18. Plate boundary that occurs as plates move away from each other
20. A break in the rock within Earth's crust
21. Area beneath Earth's surface that triggers an earthquake
23. Shaking and trembling that results from the movement of rock beneath Earth's surface

2. Wave that may occur due to an earthquake that occurs in ocean crust
3. The lithosphere is broken into...
4. Occurs when one tectonic plate sinks under another over time
5. Last name of the person who proposed the concept of continental drift and provided evidence that it occurred
6. Part of the core that is responsible for Earth's magnetic field
7. Type of seismic waves that cause the most damage to buildings and other structures
10. Measures strength of seismic waves
12. Plate boundary that may form mountains or trenches
15. Thinnest of Earth's layers
17. The outer core is made of metal in this phase
19. Point on Earth's surface above the focus of an earthquake
