Volcanoes
9. _________ lava flow has a higher viscosity so it is more ____________.
AA, Chunky/ Thick
13. Which waves CANNOT travel through liquid?
S Waves
18. Which of Earth’s layers contains tectonic plates?
Lithosphere
17. Which layer of the Earth have we been able to drill into?
Crust
4. What forms when two continental plates collide?
Mountains
10. ____________ lava flow has a lower viscosity so it is more __________.
Pahoehoe, Runny/Thin
12. Which waves can move through the Earth’s core?
P Waves
35. Which of these describes the asthenosphere? (Solid, flowing, rigid, or crust)
Flowing
22. Old crust is destroyed at___________, and new crust is formed at ___________.
Subduction Zones, Mid-Ocean Ridges
5. What forms when two oceanic plates converge?
Trenches
16. Which direction are the islands moving? (See study guide for the picture)
They are moving west (the direction that the plate is moving)
23. How many seismograph stations do you need to find the epicenter of an earthquake?
Three
8. When a continental and an oceanic plate converge, the _________ plate subducts because it is more ___________.
Oceanic, Dense
21. Earth’s crust is constantly recycled due to_________________
Mantle Convection
6. What forms when two continental plates diverge?
Rift Valleys
24. What is an area of volcanic activity far from a tectonic plate boundary?
Hot Spots
20. Which city is closer to the epicenter of the Earthquake? (Hint: Think of lag time)
(See picture on the study guide)
Miami
What is mantle convection? How does it make plates move?
Hot molten rock rises, cooled rock sinks. This pulls the plates around.
2. What are 3 pieces of evidence that tell us about Earth’s interior?
Magma from volcanoes, magnet field from the Earth’s metal core, seismic waves from earthquakes
7. What forms when two oceanic plates diverge?
Mid-Ocean Ridges
15. Which Island in this picture is the oldest? Which is the youngest? (See study guide for the picture)
1 is the oldest, 3 is the youngest
14. Why do Earthquakes usually occur at plate boundaries?
Rock in environments near tectonic plate boundaries experiences great stress.
3. What happens when two oceanic plates collide?
The more dense plate subducts, forming trenches and subduction zones.
18. Name Earth’s 5 structural layers in order.
Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core
11. What do the plates do at a transform boundary?
Slide past each other
