Science test Flashcards
What are the layers of the Earth in order from inside out?
Inner core, outer core, mantle, crust
The outer layer of Earth is broken into pieces that “float” on the gooey mantle. What are these pieces called?
Tectonic plates
One tectonic plate can slide over another because…
The densities are different
what does the p in p wave and s in s wave represent?
Primary and Secondary
What is the fastest wave
Primary wave
What is the slowest type of wave and most destructive
Surface wave
True or false: The S wave cannot travel through liquids
true
What’s Divergent boundaries?
It is when the 2 pieces move away from each other. When the Ocean/Ocean moves away then the magma under will go upwards and creates a volcano <—– ——>
What are the different types of subduction zones
Ocean/Ocean Continent.Continent
Ocean/Continent
What is subduction zone?
it is when the less dense piece would go under the more dense piece.
What is transform plate boundaries
when the plates move away from each other and create a small Earthquake.
What does brittle mean?
Fragile, able to shatter easily
What is the focus of an Earthquake
it is where the EQ is
What is an epicenter
it is the point directly on top of the focus
What type of stress occurs at a convergent boundary?
Compression
