Plate Tectonics Flashcards
The lithosphere is where you find the…
Locations of volcanoes, earthquakes, and mountain ranges.
What contains all of the outer 10 shells of the planet, crust, and upper mantle?
Lithosphere
What do you call a layer of the Earth where the rocks are soft then and partly melt becoming semi-molten?
Athenosphere or middle mantle
Where does convection current occurs?
In middle and deeper portions of the mantle.
The outer core reaches how hot?
5,000° c
What does inner core composed of?
Solid iron
What does the heat of the inner core generated by?
Uranium
How hot does the inner car reaches up to?
6,000° c
What are seismic waves?
Mechanical vibrations release from the focus of the earthquake. Seismic waves are earthquake generated and recorded on a seismograph.
What kinds of waves does surface waves have?
Love waves and Rayleigh waves
What kinds of waves does body waves consist of?
Primary waves and secondary waves
Is p-waves faster than s-waves?
Yes
What can primary wave travel through?
Solids, liquids, and gases.
How does primerary wave move?
They move forward and backward as they are compressed and expanded
What does Secondary wave travel through?
Solids only
