Two differences between S waves and P Waves.
S waves are slower, more destructive and cant pass through Liquid or gases.
These are the three chemical layers of earth.
What is crust, mantle, core?
When it only takes one allele to show the trait.
Dominant
Something that will change an object's speed and/or direction
Unbalanced Force
What are two mechanical layers of earth's interior.
lithosphere, asthenosphere, mesosphere, inner core, outer core
These land features are long mountain ranges on the ocean floor where sea floor spreading occurs.
What is Mid-Ocean Ridges?
Two destructive processes
Erosion and Weathering
The different variations of Genes are called what?
Alleles
A change in position of an object is always judged and described by this?
Reference point
Two constructive landforms created through deposition?
Answers Vary
(sandbars, deltas, sand dunes, stalactites)
Which criteria make for a useful index fossil?
recognizable, widespread, limited time span
These are the three types of plate boundaries
Convergent, divergent, transform
Meiosis results in what?
4 Haploid daughter cells (gametes)
Two factors that affect electric/electrostatic force?
charge and distance
Which type of non-mendelian heredity is expressed as a blending of two phenotypes?
What are three pieces of evidence collected and described by Wegener?
Fossils, Mountains, glacial landforms, climate evidence
This occurs when a plate slides under another plate because of density.
Subduction.
Mitosis results in what?
2 Diploid identical cells
Newton's first law is the law of what?
Inertia
List four stages of mitosis in order
PMAT
These are the main pieces of evidence to support sea-floor spreading.
magnetic Poles Reversing, volcanism at mid-ocean ridges, and age of rock.
This is the term to describe the most dense materials sinking to the middle of earth when forming. Hint: It's really different.
Planetary Differentiation
physical features expressed due to present alleles
Phenotype
F=MA
one positive and one negative of sexual reproduction
More genetic diversity,
energy/time cost
These cause random volcanoes to occur througout earth, where magma finds cracks and make thier way to the surface.
Hot Spots.
When plates converge, what are the two land features that form?
Deep Ocean Trench, Volcanic Mountain Range, island arcs
Which genotype includes variations of an allele?
heterozygous
Describe Newton's Third law.
For every Action there is an opposite and equal reaction.
Variations/mutations in alleles, resulting in a trait that makes an organism more likely to survive in its environment, reproduce, and pass traits to the next generation?
Adaptation
