THE EARTH’S DYNAMICS
Start
Seismic and gravimetric methods
Igneous and metamorphic methods
Direct and indirect methods
Direct and magnetic methods
What are the two main methods used to study the Earth's interior?
QUESTION 01
WOW!
Comparative method using meteorites
Seismic method
Magnetic method
Gravimetric method
Which indirect method has provided the most information about the Earth's interior?
QUESTION 02
WELL DONE!
Faster waves that can travel through solids and liquids
Waves that measure magnetic properties
Waves that travel only through the Earth's surface
Waves that are slower and unable to travel through liquids
What are P waves in the seismic method?
QUESTION 03
WELL DONE!
They are reflected at the Earth's surface
They only propagate in magnetic fields
They are absorbed by solid materials
They cannot travel through liquids
Why can S waves not travel through all materials inside the Earth?
QUESTION 04
WELL DONE!
A layer made of completely liquid materials
A region where waves completely stop propagating
A boundary where seismic wave speed changes suddenly
A point where waves accelerate uniformly
