Earth Science #1
These are the two layers S Waves can't travel through. Why?
What is outer and inner core Can't travel through liquids
These are the 4 compositional layers of earth.
What is crust, mantle, outer core, inner 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 close to the inner core this happens to the objects density.
What is decrease?
The different variations of Genes are called what?
Alleles
What are the two types of energy?
Potential and Kinetic
Use T, t Genotype for homozygous dominate?
TT
Name of the scientist who proposed continental drift theory.
Alfred Wegner
These are the three types of plate boundaries
Convergent, divergent, transform
Meiosis results into how many daughter cells? Identical or Different? Haploid or Diploid?
4 - Different - Haploid cells
If an object has a net force of 0N. Is this Balanced or Unbalanced?
Balanced
If a person is pushing a box at 45N to the east, while friction is opposing with 30N of force. What is the Net Force on the box? Is this balanced or unbalanced?
15N to the East. Unbalanced b/c it is in motion.
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 into how many daughter cells? Identical or different? Haploid or Diploid?
2 - Identical - Diploid cells
The tendency to resist motion. More mass means more ?
Inertia
O-O convergent boundaries create what 2 land features?.
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.
As you go down into the earth's layers, how does pressure, temperature, and density differentiate (Increase or Decrease)? Provide an answer for each variable.
Pressure and Temperature INCREASE. Density DECREASES.
This is the physical features we see (like color of eyes)
Phenotype.
What are the 3 variables that make up Newton's 2nd Law of Motion?
F=MA
These cause random volcanoes to occur througout earth, where magma finds cracks and make thier way to the surface.
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 gene combination that make up a trait.
Genotype.
Describe Newton's Third law.
For every Action there is an opposite and equal reaction.
Evidence for Continental Drift?
fossils, climate change, Land features, fits like puzzle
