What does the Global Positioning System depend on? 35. What type of fault is the San Andreas fault? Fill in the blanks/completion: -know the following terms: Slab pull, ridge, push, convection 1. Crust moves sideways because of ______________ 2. Crust moves downward because of _______________ -know the following terms: Crust, compound, mantle, mineral 1. A ______________________ is a substance composed of two or more elements. 2. Older ____________ is farther away from the mid-ocean ridge than the younger crust is. -know the following terms: Seismic wave, tectonic wave 1. A ____________ traveling through a solid will travel faster than a seismic wave traveling through a liquid. -know the following terms: Transform boundaries, convergent boundaries, divergent boundaries 1. Because tectonic plates have irregular surfaces, they grind and jerk as they slide in ________________, which produce earthquakes. -know the following terms: Folding, compression, fault, tension 1. 2. 3. 4. 5.

When tension breaks a rock layer it makes a __________ fault. Tectonic plates move together to form a _________________ boundary. When compression breaks a rock layer it makes a ____________________ fault. Magnetic minerals prove Earth has had ________________ New crust in the ocean is a sign of ________________ Tectonic plates move apart to form a ___________________ boundary. Short Answer/Essay: 1. How do fossils help prove that the continents move? 2. What was Pangea? 3. Tectonic plates forming a transform boundary may move only a few centimeters each year. Can even this small movement affect people and communities living near a transform boundary? Explain your answer.
