Plates slide past each other along this type of boundary, and this is the landform it creates.
What are transform boundaries, and what are faultlines?
These geological features are formed when two oceanic plates collide.
Deep Ocean Trenches
Volcanic Arc Islands
These are the two types of Earth's crust, and the first mentioned should be the least dense layer.
What is Continental and Oceanic Crust?
In the Modeling Plate Tectonics Lab, what did the graham cracker, fruit by the foot and icing represent?
GC=continental crust
FBTF=oceanic crust
icing=magma
The East African Rift Valley is a resulting formation of what type of plate boundary?
Continental Divergent PLate Boundary
When oceanic crust sinks below continental crust, these are the resulting landforms:
Deep Ocean Trenches
Coastal Volcanic Mountain Ranges
Subduction Zone
When two oceanic plates converge this determines which crust will submerge.
What is the density of the plates. (The most dense will submerge.)
Plates that come together are called a _______ boundary, and these are all of the types of this boundary.
What is convergent boundary?
What are continental-continental convergent boundaries?
What are oceanic-continental convergent boundaries?
What are oceanic-oceanic convergent boundaries?
The Volcanic Cascade Mountains found on the west coast of Washington and Oregon are the resulting formation of what type of plate boundary?
What explains the formation of mountains?
Two pieces of continental crust collide at a convergent plate boundary.
This describes what drives the motion of tectonic plates.
What are Convection Currents in the mantle (asthenosphere)?
When two oceanic plates diverge (move apart), is land created or destroyed?
Land is created.
The Mariana Trench is the deepest part of the pacific ocean and is the resulting formation of what type of plate boundary?
Oceanic - Oceanic Convergent Plate Boundary
This describes and explains the formation of a mid-ocean ridge.
At oceanic divergent plate boundaries, magma rises on the ocean floor, cools and hardens to form a mid-ocean ridge.
This drives convection currents in the mantle and explains why there is movement in Earth's interior.
The lower part of the mantle is the hottest, since it is closest to the heat of Earth's core. The hotter magma is less dense and rises. As it cools near the Earth's surface, it sinks back down, and this cycle of rising and falling continues due to changes in the temperature and density of the magma.
At these 2 types of boundaries, crust is both created and destroyed. Explain how this is true.
What are oceanic-oceanic convergent boundaries and oceanic-continental convergent boundaries?
Crust is being destroyed/recycled at subduction zones, as the more dense plate sinks below the less dense plate. Also at the subduction zones, magma is rising to the surface to form coastal or underwater volcanoes and arc islands, which is new crust.
Using only your hands to show movement (NO WORDS OR SOUNDS!) show each type of plate boundary. (There are 6.)
All group members must participate and do these motions together...
While smiling.
The Aleutian Islands are formed when two oceanic plates collide. Describe why a string of volcanic islands form on the overriding plate, opposite of the subduction zone.
The volcanoes form opposite of the subduction zone because the older, more dense, sinking plate is destroyed and pushes magma to the surface forming a volcanic mountain range.
On your whiteboard, draw an oceanic divergent plate boundary. Then draw convection currents that are driving this movement, being sure to use arrows to show movement in both the plates and the direction of flow in the convection currents.
Show your teacher your white board.
What is an overriding plate?
The plate which remains on top at the subduction zone when two plates collide?
