| Question | Answer |
|---|---|
| Name the layers of the earth from the INSIDE out. | inner core, outer core, mantle , crust |
| Which layer of the earth is solid and made of iron and nickel? | inner core |
| The largest layer of the earth is the | mantle |
| Under the lithosphere is the | asthenosphere |
| Plates move apart at | DIVERGENT BOUNDARIES |
| Plates come together at | CONVERGENT BOUNDARIES |
| Plates slide past each other at | TRANSFORM BOUNDARIES |
| The type of heat transfer caused by differences in density is | CONVECTION |
| What are the 3 types of convergent boundaries? | continent/continent ocean/ocean continent/ocean |
| What type of boundary creates NEW SEA (OCEAN ) floor? | DIVERGENT |
| At what type of boundary is old ocean crust destroyed? | CONVERGENT |
| What is a subduction boundary? | Where one plate sinks under another |
| Why is the ocean plate always the one to subduct? | Because it is more dense!!!! |
| What mountain range was created by India and China colliding? | Himalayas |
| Is the mid-atlantic ridge completely underwater? | No! It pops up at Iceland |
| The San Andreas Fault in California is an example of a ________ boundary. | TRANSFORM (sliding) |
| Ocean plates are made of | BASALT |
| Continental plates are made of | GRANITE and they are less dense than ocean plates |
| What is a tsunami? | A giant wave created by plate motion |
| This chain of volcanic mountains was created when the pacific plate subducted under the south american plate. | THE ANDES |
| Where can we find the deepest focus earthquakes? | At ocean/ocean boundaries |
| Islands arcs are formed from what type of boundary? | Ocean/ocean |
| Name 3 pieces of evidence that Wegener used to support his theory. | 1. Fit of continents 2. Matching fossils on widely separated continents 3. Matching rocks on widely separated continents |
| Why did the scientists of his time not accept Wegener's theory? | He could not explain how or why continents would drift in the ocean |
| Name 2 pieces of evidence to support the idea of Sea Floor Spreading. | 1. Ocean crust is youngest at the ridge. 2. Ocean crust is hottest at the ridge. |
| The Mid-Atlantic Ridge is an example of a __________________ boundary. | DIVERGENT |
| The Andes Mountains is an example of a ___________________ boundary. | CONVERGENT |
| The San Andreas Fault is an example of a ____________________ boundary. | TRANSFORM (sliding) |
| Make sure you understand and can label the divergent and convergent pictures that you have in your notes and that we have been looking at in class!!!!!!! | What are you waiting for.........go study the pictures NOW!!!! |
