FORCES & STRESS
a force that pulls rocks apart from opposite sides.
What is TENSION?
Two tectonic plates move past one other.
What is a TRANSFORM BOUNDDARY?
A curve line of volcanoes that forms parallel to a plate boundary.
What is a VOLCANIC ARC?
Type of fault in which two plates slide past one another.
What is a TRANSFORM FAULT?
Mountain Ranges produce by compression stress at convergent plate boundaries
The HIMALAYAS are an example of a ?
A parallel forces acting in opposite direction on a rocks.
What is SHEAR?
Two tectonic plates move away each other.
What is a DIVERGENT BOUNDARY?
is an area of many fracture pieces of a crust along a large fault.
What is a FAULT ZONE?
is a chain of volcanoes created in the ocean where oceanic plates converge and one plate subducts under another one.
What is an ISLAND ARC?
transform fault produce by shear stress at transform plate boundaries.
The San Andres Fault is an example of a?
Is a type of stress that can fold the rocks of the crust.
What is COMPRESSION?
Two tectonic plates collide each other.
What is a CONVERGENT BOUNDARY?
Are deep landforms, underwater created by one oceanic plate subducting under another oceanic plate at convergent plate boundary.
What are OCEAN TRENCHES?
they form under water where oceanic plates diverge by tension stress.
What are MID-OCEAN RIDGES?
continental rift formed by tension stress when divergent boundaries occurs within a continent.
THE EAST AFRICA RIFT is an example of a?
Is a force to move a way the lithosphere in opposite directions.
What is a RIDGE PUSH?
Earth's surface is made of rigid slabs that move with respect to each other.
What Plate Tectonic THEORY states?
The largest landforms on Earth.
Are produce by COMPRESSION stress at CONVERGENT plate boundaries?
in an area between two ridges created by a tension stress when large blocks of crust move downward.
What is a VALLEY?
volcanic arc in California produce by a compression stress at convergent plate boundaries.
MOUNT SHASTA is an example of a?
Is a force that causes motion produced it by convection currents.
What is a BASAL DRAG?
Process in which the denser plate sinks below the more buoyant plate.
What is SUBDUCTION?
is a landform created by a tension stress at divergent boundaries when two continental plates move a part.
What is a CONTINENTAL RIFT?
there 40 active volcanoes in Alaska formed as a result of the Pacific plate subducting under North American Plate.
What are the ALEUTIAN VOLCANIC ARC?
mid-ocean ridge off the coast of Washington and Oregon, created by a tension stress under the ocean at divergent plates boundaries.
THE JUAN DE FUCA RIDGE is an example of a?
