Earth's Layers and Plate Tectonics
This layer of the Earth is the outermost, solid layer.
What is the CRUST?
The name for the giant landmass that had all of the continents pushed together.
What is PANGAEA?
The process by which rocks change shape when under stress.
What is DEFORMATION?
Magma that has reached Earth's surface.
What is LAVA?
Solid, dense part of the Earth. Is at the center.
What is the inner core?
The solid, dense center of the Earth that extends from the bottom of the outer core to the center of Earth.
What is the INNER CORE?
The process when molten rock inside Earth rises through the cracks in the ridges, cools, and forms new oceanic crust.
What is sea-floor spreading?
The crack that forms when large blocks of rock break and move past each other.
What is a FAULT?
the movement of material due to differences in density that are caused by differences in temperature
What is Convection?
outermost, solid, compositional layer of Earth
What is the crust?
The scientist who first proposed the theory of CONTINENTAL DRIFT.
Who was Alfred Wegener?
The pieces that the lithosphere is divided into.
What are tectonic plates?
What is the hanging wall drops down?
the crack that forms when large blocks of rock break and move past each other
What is a Fault?
the compositional layer of the Earth that is located between the core and the crust.
What is the mantle?
The COMPOSITIONAL layers of the Earth.
What is the Crust, Mantle, and Core?
The three types of plate boundaries.
What are divergent boundaries, convergent boundaries, and transform boundaries?
The three kinds of mountains.
What are Folded Mountains, Volcanic Mountains, and Fault-Block Mountains?
a boundary where two plates move away from each other
What are divergent boundaries?
the compositional layer of Earth extends from below the mantle to the center of the Earth
What is the core?
Earth's Physical Layers.
What are the Lithosphere, Asthenosphere, Mesosphere, Outer Core, and Inner Core?
Many scientists believe that this is the most important mechanism driving tectonic plate motion.
(when a denser plate pulls the rest of the plate with it?
What is Slab Pull?
Stress that pushes rocks in parallel but opposite directions.
What is SHEAR STRESS?
a boundary at which two plates move past each other horizontally
What are transform boundaries?
a layer of weak or soft mantle that is made of rock that flows slowly. Tectonic plates move on top of this layer. Physical layer
What is the asthenosphere?
