Where are earthquakes most likely to take place?
along the core-mantle interface
where the composition of the Earth tends to be uniform
near the Earth's Equator
near a fault zone
The inference that the inner core of the Earth is solid is based on analysis of
seismic data

It is suggested that the outer core of the Earth is liquid. Which is the strongest evidence for this?
P-waves disappear as they move through the outer core
S-waves disappear as they move through the outer core
S-waves speed up as they move through the outer core
P-waves are transmitted through the outer core

The difference between a theory and a hypothesis in science
A hypothesis is a prediction and a theory is a conclusion
A hypothesis is an idea with some backing. A theory has a large amount of backing and is accepted as truth.
A hypothesis is accepted as truth. A theory is an idea presented as the early stages of a hypothesis
