Name the three types of plate boundaries and show me the directions with your hands.
Convergent, Divergent, Transform
What is the Continental Drift Theory
The theory that Earth's continents were once combined (Pangaea) and have since spread out and continue to move
What is weathering?
Break down of rocks due to elements?
What landforms are associated with Divergent boundaries?
Volcanoes and Ridges
S-P: shows you how far because S travels 1/2 as fast as P
Triangulation!
What is erosion?
Movement of weathered particles
Plates float on top of the _______________________.
What is the asthenosphere
Tell me 3 pieces of evidence that support CDT!
1. Flora and fauna
2. Mountain Ranges
3. Satellite data shows continents moving
4. Fossil Evidence
Come up to the board and draw an earthquake. Include: fault, hanging wall, foot wall, epicenter, focus.
What are the main types of weathering (3)
Physical, Chemical, Biological
What is Cinder: EXPLOSIVE
Shield: Oozes
Composite: Either Way
Fissure: Long Crack
The rigid part of the Earth including the crust and the upper mantle (makes up the plates of the Earth)
What is the lithosphere
Explain seafloor spread?
Divergent plate boundaries in ocean create new oceanic crust in center of boundary.
This is the mechanism (what causes) the plates to move
What is convection currents in the mantle
What are the different types of erosion?
Wind, Water, Gravity, Ice
Describe why plates move on Earth's surface using the terms: asthenosphere, lithosphere, and convection currents. You may draw a picture to explain.
Name the landforms associated with...
Continental-Oceanic Convergent Boundary
Continental-Continental " "
Oceanic-Oceanic " "
Volcano
Mountains
Trench
How long ago was PANGEA whole?
Around 250 million years
What is subduction (Oceanic Plate under Continental because O is more dense) and forms a volcano due to increase in water in asthenosphere--> lower melting point
What is the most delicious food on the planet?
IDK if your answer is creative you get the points
