Earth Science #1
These are the two states of matter S Waves can't travel through.
What is Gas and Liquid?
These are the 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.
Theory that big slabs of Earth's Crust is able to move/shift over time.
Plate Tectonics
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.
Decrease in density due to higher temperature.
The different variations of Genes are called what?
Alleles
What are the two types of energy?
Potential and Kinetic
What is the difference between sexual and asexual reproduction?
Sexual: genetic variation, slower, more mutations, need a partner
Asexual: no variation, fast, less mutations, no partner
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
Two factors that affect gravitational attraction between two objects.
Distance and mass
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
Newton's first law is the law of what?
Inertia
Two factors that affect magnetic attraction between two objects.
Distance and poles (North and South).
These are the three main pieces of evidence to support sea-floor spreading.
Magnetic poles Reversing, pillow lava at the ridge and age of rock youngest at the ridge and gets older farther away.
This is the term to describe the most dense materials sinking to the middle of earth when forming.
Differentiation
This is the physical features we seen form reproduction.
Phenotype.
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 genes that are interacting.
Genotype.
Describe Newton's Third law.
For every Action there is an opposite and equal reaction.
What are the 4 types of fossils?
What is cast, mold, trace and body fossils?
