Plate Tectonics
large, thin, relatively rigid layers in Earth's crust that constantly move in relation to one another
What are plates?
The movement of Tectonic plates are caused by...
What are convection currents
The thinnest layer of Earth.
What is the Crust?
vibrations caused by the shifting of the tectonic plates of Earth's crust; often mild but sometimes very destructive
What are earthquakes?
All plate movement makes this natural disaster
What is an earthquake?
a theory that states that Earth's crust is made of plates that are in constant motion
What is Plate Tectonics?
The material that comes up during a divergent boundary movement.
What is Magma?
The Layer that is made of molten rock and contributes to the movement of tectonic plates.
What is the mantle?
Waves made by Earthquakes
What are Seismic waves?
Convergent plate movement make this natural boundary
What is a mountain?
a theory that says all of Earth's continents were once joined together and have moved apart over time with the shifting of plates
What is Pangea?
When two tectonic plates slides past each other horizontally.
What is transform boundaries
Contributes to the layering inside of the Earth.
What is Density?
instrument that measures and records the shaking, or vibrations, of Earth's crust
What is a seismograph?
Divergent plate movement makes these boundaries
Hint: Theres 2 boundaries that are made
What are rifts/ridges and volcanoes?
the part of earth's structure that consists of tectonic plates
What is the crust? (Or Lithosphere)
3 types of convergent boundaries.
What is Continental - Continental,
Oceanic - Oceanic, and Continental and Oceanic
The state (solid/liquid/gas) and material that makes up the inner core.
What is pressurized/ Solid Iron and Nickel?
scale used to rate the strength of an earthquake
What is the Richter scale?
Earthquakes and seismic waves on oceanic plates can create these natural disaster.
What are Tsunamis?
The Geologist that came up with the Continental Drift Theory.
Who is Alfred Wegener?
BONUS: What were the evidence that proved his Theory?
The area of a tectonic plated goes under another is called
Hint: This deals with the density of the two types of tectonic plates
What is the subduction zone
Made by the movement of Liquid Nickel and Iron in the Outer Core
What is the magnetic Field?
The Waves that are picked up from seismographs.
What are p and s waves?
BONUS: Which waves is longitudinal and transverse
the length that a tectonic plate moves per year
What is 2-3 cm?
