Which of these are likely to happen because of an earthquake?
destroyed buildings
fires
floods
all of these!
What happens when tectonic plates move and release energy?
The crust shakes causing an earthquake.
Literally nothing.
Thunderstorms.
A mountain instantly forms.
What can scientists find out from analyzing seismographs?
The epicenter of an earthquake.
The depth and density of the layers of earth.
They can learn about the epicenter AND the depth and density of the layers.
Literally nothing.
Where do earthquakes happen?
At plate boundaries
Where plates interact.
Both of those other answers are correct because they are basically saying the same thing.
A deep earthquake causes more violent shaking at the surface.
True
False
In poorer areas, devastation may be worse because structures are not built strong enough to resist earthquakes.
True
False
Do P and S waves move the same through solids (like rocks)?
Yes, of course!
No?
No, P waves move quickly through solids, S waves move more slowly.
No, P waves move slowly through solids, S waves move more quickly.
How did scientists figure out that the inside of the earth is liquid?
It isn't.
They know that S waves don't move through liquid, so they concluded the core of earth must be liquid since the S waves don't go all the way to the other side of the world after a quake.
Don't choose this one. The long answer is it.
Seriously, why are you even reading this one?? :P
