Inside the Earth
The very center of the Earth, made of solid metal.
The INNER CORE
The piece of evidence that everyone can see.
The continents fit together like puzzle pieces.
The 'cracks' in the Earth's crust are called __________.
FAULTS
When tectonic plates crash into each other.
CONVERGENT
During convergence, when continental plates crash, _________________ will form.
Mountains
Made of solid rock, very thin.
The CRUST.
The original evidence from 1910.
Matching fossils and rock formations.
The large pieces of the Earth's crust are called _______.
PLATES
When plates DIVIDE apart.
DIVERGENT
At the bottom of the ocean, where plates are dividing, _______________ are created.
Mid-ocean RIDGES.
This layer is made of 'molten' (extremely hot liquid) metal.
The OUTER CORE.
The final evidence found in 1960 deep under the ocean.
Mid-ocean ridges and deep-ocean trenches.
What do all the largest PLATES have on them?
The CONTINENTS!
When plates SLIDE BY each other.
TRANSFORM
When an oceanic plate subducts under a continental plate, __________________ form.
TRENCHES
This layer is split into layers of rock. The lowest layer is solid rock, but the upper layer is 'molten' rock that moves.
The MANTLE.
What does 'continental drift' mean?
The idea that the continents are moving.
How do scientists know where the FAULTS are in the crust?
We can see them!
When plates crash/converge, an oceanic plate will sink under a continental plate. What is that process called?
SUBDUCTION
Dividing plates leave large _________________ when they split.
VALLEYS
The Layers inside the Earth where plate movement happens.
The ASTHENOSPHERE and LITHOSPHERE.
What does 'plate tectonics' mean?
The entire CRUST of the Earth is moving, not just the continents.
What is the term for the place where 2 PLATES meet?
A BOUNDARY.
EARTHQUAKES
Mountains, volcanoes, and earthquakes on Earth are found where?
At plate boundaries, on fault lines.
