Activity 46- Convection Currents
Study Guide
Thursday, December 10, 2015
Daily Objective:
Today we will investigate how convection currents cause plates to move.
Daily Question:
Explain what happens at a continental-oceanic convergent plate boundary.

2. Convergent Plate Boundary Oceanic/continental
asthenosphere - is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement
Subduction - process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates converge
Ex: Andes Mountains
Cascade mountain Range
Subduction

3. Continental/Continental Convergent Plate Boundary
Earthquakes
Mountains
Ex:
Himalayan Mts.

4. Oceanic/Oceanic Convergent plate boundary.
Trenches
Volcanic Island mountains
Earthquakes
Ex: Solomon Islands

5. Hot Spots
Hot Spot: volcanic regions thought to be fed by underlying mantle in which magma is trapped and hot compared with the mantle in other places.
Ex: Hawaii & Yellowstone
