Universe to Earth
This is the most widely accepted explanation for the moon's formation.
What is Giant Impact Hypothesis?
(Mars sized planet collided with early Earth).
This is the lithosphere.
What is the crust and upper mantle?
This is the term for mapping the ocean floor.
What is bathymetry?
This type of plate boundary creates new lithosphere.
What is a divergent plate boundary?
A light year is a unit of this.
What is distance?
Earth's spherical shape is caused by...
What is gravity pulling material closer to the center?
(Gravity and rotation)
This lies directly below the lithosphere.
What is the asthenosphere?
He proposed the concept of continental drift and coined the supercontinent of Pangaea.
Who is Alfred Wegener?
This island chain is a classic example of a hot spot.
What is Hawaii?
The dipole nature of Earth's magnetic field explains this.
Why compasses align with the magnetic north?
This evidence most directly supports the Big Band Theory.
What is cosmic background radiation (static on TV)?
This is what marks the crust mantle boundary.
What is the Moho?
This occurs when continental lithosphere stretches and thins.
What is a continental rift?
This force pulls a tectonic plate downward at a subduction zone.
What is slab-pull?
Increases in temperature and pressure with depth.
What is the geothermal gradient?
This is what the expanding universe concept is directly supported by.
What is Red-shift measurements of distant galaxies?
Differentiation occurred early in Earth's history when this occurred.
What is materials separated based on density?
The width of magnetic strips on the seafloor are used to calculate this.
What is seafloor spreading rates?
Continental rocks differ from oceanic due to this.
This composition differentiates between terrestrial and Jovian planets.
What is rocky and gas giant planets?
This three sequences that represent the formation of the universe, then elements formed in stars, then the remaining elements on the periodic table resulted from.
What is the Big Bang, Stellar Nucleosynthesis and Supernova Nucleosynthesis?
(Big bang -> Stellar -> Supernova)
These are the layers of Earth's atmosphere from the surface of the Earth upwards towards space.
What is troposphere, stratosphere, mesosphere and thermosphere?
Paleomagnetism provides evidence for continental drift because Fe does this.
What is preserve the direction of Earth's magnetic field at formation?
This is why Alfred Wegener concept of continental drift was initally rejected.
What is he lacked the mechanism explaining continental movement?
Elements up to Fe are primarily produce during this.
What is stellar nucleosynthesis?
