What forces are always acting on an object.
Gravity and norm force
The name of the super continent.
What is pangea?
What feature is at a divergent O-O boundary?
What is Mid-Ocean Ridges?
As the magma flows close to the inner core this happens to the objects density.

If a race car is going around a circular track at a constant speed of 90 MPH is it accelerating?
Yes! It is changing directions
Use T, t Genotype for homozygous dominate?

Why is the inner core a solid if it is so hot?
pressure compacts the molecules back together
Which is older the cut or the rocks the cut goes through?

O N
Scientist who proposed the idea of sea floor spreading.
Who is Harry Hess?
In a convection current, the less dense material rises or sinks?
rises
This occurs when an oceanic plate slides under a continental plate because of density.
Subduction.

island arcs, trenches?
These are the three main pieces of evidence to support sea-floor spreading.
Magnetism Reversing, shape of rocks and Relative age of rock.
What 2 things cause our Earth to have layers?

What is the genotype for a purebred? use R or r
RR or rr
Can a moving object be a balanced force?
Yes, No change in motion - Net force is 0N
Evidence for Continental Drift?
fossils, climate change, Land features, fits like puzzle
