Vocabulary
The thinnest layer of the Earth
What is the crust
There are ______________ main layers of the Earth.
What is four
Boundary where two plates pull apart or separate from one another.
What is a divergent Plate Boundary?
Earthquakes and Volcanoes are usually located in relation to these
What is a plate boundary
Massive slabs of solid rock, generally composed of both continental and oceanic lithosphere
What is tectonic plates.
Boundary where two plates collide.
What is convergent boundary?
Forces in the mantle that cause massive plates to move
What is convection current?
The theory that all continents are fragments of Pangaea now drifting apart
What is the Continental Drift Theory
Layer that is in a liquid state.
What is the outer core?
Boundary where two plates grind horizontally past each other.
What is a transform Plate Boundary?
Relative age of rocks as you move away from the mid-ocean ridge
What is the rocks get older?
Process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity at divergent plate.
What is seafloor spreading?
One difference between the continental crust and the oceanic crust.
What is the continental crust is thicker or it is less dense or it is made of granite?
Identify two events that occur at a divergent plate boundary?
What are seafloor spreading, creation of new igneous rocks, formation of rift valley, earthquakes, etc.
Largest belt of active volcanoes and earthquakes in the world
What is the ring of fire?
location where magma rises upward from the Earth's mantle, remaining in a fixed position while burning holes through the moving tectonic plate; created the Hawaiian Islands
What is a hot spot
Although the hottest layer of the Earth, this layer is solid metal
What is the inner core
Process that is primarily responsible for the heat produced in the mantle; this process drives convection current, plates movement and volcanic eruption.
What is Radioactive decay?
Identify two events that occur at a convergent plate boundary.
What are volcanoes, earthquakes, subduction, formation of trenches, etc.
Name Two of the major tectonic plates.
What are the African plate, North American plate, Pacific Plate, Eurasian plate, South American Plate, caribbean plate, etc.
Name two differences between the P-wave and the s-waves
What are the P-wave travels faster than the s-wave; the P-wave can travel through liquids and solids, but the S-wave only travels through solid; the p-wave travel in a push and pull direction, while the s-wave travels in a side by side direction; p-waves are less destructive, etc.
