LAYERS ON LAYERS
The layer of the Earth that is the thickest & contains most of its mass.
What is the core?
This fault forms along a Transform Boundary.
What is a Strike-Slip Fault?
This stress forms because of plates converging.
What is compression?
The idea that the continents were once joined together in a single land mass, then slowly moved apart.
What is Continental Drift?
This boundary forms when two plates move apart.
This layer is broken into pieces called tectonic plates.
What is the Crust/Lithosphere?
I'm not talking about sheep! This stress forms as plates move alongside each other.
What is shearing stress?
The supercontinent that existed about 254 million years ago.
Mountains/volcanoes form near this boundary.
What is a Convergent Boundary?
A layer of molten/liquid iron and nickel surrounding the Inner Core.
What is the Outer Core?
In this fault, the hanging wall moves down.
What is a normal fault?
The stress that forms as plates diverge.
What is tension?
Landforms, climate, and _______ are evidence of Continetal Drift.
What are fossils?
These boundaries frequently cause earthquakes.
What are Transform Boundaries?
Geologists think convection currents flowing in it push tectonic plates around.
What is the Asthenosphere?
When shearing stress is too great, so the rock cracks and creates an earthquake.
What is a Strike-Slip fault?
You know stress was released when one of these events happen.
What is an earthquake?
The process proved Wegener's theory, but was not discovered until after World War II.
What is Seafloor Spreading?
Besides mountains/volcanoes, these landforms are created as one plate converges with another.
What are Trenches/Subduction Zones?
This compositional layer includes the Asthenosphere & the Mesosphere.
What is the Mantle?
What is the focus?
There's no need to stress out about this test. All you need to remember is that plates are slowly moving all the time. It's the theory that connects all of geology.
What is Plate Tectonics?
Hawaii was formed as the Pacific Plate drifted over it.
What is a Hot Spot?
It's not just a Johnny Cash song. It's the name of the volcanic belt around the Pacific Plate.
What is the Ring of Fire?
