What medium can't S Waves travel through.
What is Liquid.
These are the three chemical layers of earth.
What is crust, mantle, core?
When it only takes one allele to show the trait.
Dominant
What force is always acting on an object.
Gravity.
The name of the super continent.
What is pangea?
These land features are long mountain ranges on the ocean floor where sea floor spreading occurs.
What is Mid-Ocean Ridges?
As the magma flows closer to the inner core this happens to the magma's density.
increases
The different variations of Genes are called what?
Alleles
This is how you can tell that an object is in motion. The object is compared to a what?
Reference Point
A specific trait can be traced down through generations in a family using this.
What is a pedigree?
Name of the scientist who proposed continental drift theory.
Alfred Wegner
These are the three types of plate boundaries
Convergent, divergent, transform
Meiosis results in what?
4 Haploid cells
The scientist who discovered Gravity.
Sir Issac Newton
Scientist who proposed the idea of sea floor spreading.
Who is Harry Hess?
This is the name of the current that moves magma in the mantle.
Convection Current
This occurs when an oceanic plate slides under a continental plate because of density.
Subduction.
Mitosis results in what?
2 Diploid cells
When all the forces acting on an object are balanced, the object is said to be in this.
constant or no motion
Niagara Falls is created through the process of what?
Erosion
This is a piece of evidence to support sea-floor spreading.
Poles Reversing, pillow lava, and age of rock.
Ice cores have shown us that as this increases, so has carbon dioxide levels.
What is the temperature?
This is the physical features we seen form reproduction.
Phenotype.
When making an electromagnet, this is how you can increase the strength of the magnetic force.
adding more coils
These cause random volcanoes to occur throughout earth, where magma finds cracks, and makes their way to the surface. Hint: Hawaiian Islands
Hot Spots.
When an Oceanic and Continental plate collide, what are the two land features that form.
Deep Ocean Trench, Volcanic Mountain Range
These are the genes that are interacting to create specific traits.
Genotype.
These forces act in the opposite direction of gravity and motion.
Normal force and friction
What did Mrs. Tozer teach before science?
instrumental music
