Seismic Waves
What did scientists use to study the interior of the Earth?
Seismic waves
What are the three chemical layers?
The crust, mantle, core
Created from Continental-Continental Converging Plates
Mountains
What is a divergent boundary
When two plates move away from each other
In convection currents, which temperature of air rises?
Warm air
What are seismic waves?
a wave of energy that is
generated by an earthquake or other
earth tremble and that travels within the
earth or along its surface
What increases the deeper you go into the Earth?
Temperature and pressure
Created from Oceanic-Continental Converging Plates
Volcanoes
What are the three types of plate boundaries?
Transform, convergent, and divergent
Why does warm air rise?
Because it is less dense than cold air
Instrument used to measure seismic waves
Seismometer
What is a Tsunami?
A series of large waves caused by the movement of a large amount of energy through the water.
Which type of boundary forms when tectonic plates slide past each other?
Transform plates
In what layer of the Earth, do convection currents occur in?
The mantle
Which type of seismic wave can only through solid materials?
S waves
What physical layer of Earth contains the magnetic field?
The outer core
Created deep in the ocean from diverging plates
Trenches
An area of the Earth that contains around 90% of the world's earthquakes and 75% of its active volcanoes
Ring of Fire
Radioactive isotopes or heat from the core
How are P waves generated?
by sudden compression or
extension of the ground at the earthquake site
What physical layer of Earth acts like grease or a plastic to help move the plate tectonics?
The asthenosphere
Created from converging plates deep in the ocean
Ridges
When two plates collide, one plate subducts or goes underneath another plate. Which plate will go under the other? Like what characteristic does it have?
The more dense plate will go under the less dense plate
The atom U-235 undergoes alpha decay to become this.
