The Sun and Stars
These two elements make up most of the sun's mass.
What are hydrogen and helium?
This is when the universe is thought to have begun.
What is approximately 14 billion (13.8) years ago?
Oceanic and Continental.
What are the two types of crust/lithosphere?
This is where most of the world's earthquakes occur.
What is the Ring of Fire/Pacific Ocean?
This type of stress will cause materials to bend or kink.
What is compression?
This is what causes an aurora. (The Aurora Borealis.)
What is the interaction of solar wind and the Earth's atmosphere.
Millions and millions of stars, planets, moons, and gases held together by gravity.
What is a galaxy?
This type of plate movement will destroy old crust/lithosphere.
What is subduction/convergent boundary?
This causes most of the world's earthquakes.
What is the movement of tectonic plates?
This type of stress will cause materials to pull apart.
What is tension?
This is a solar flare.
What is a violent, explosive release of solar energy?
Dark matter and dark energy.
What are the things that make up most of the universe?
This is the type of plate movement where the plates are moving away from each other.
What is a divergent plate boundary?
This is where most of the continental United States earthquakes occur.
What is California?
This type of stress will cause a building to fall over.
What is shear?
The explosion of a dying star.
What is a supernova?
Thousands of galaxies located in one part of the universe.
What is a supercluster?
The type of plate movement where oceanic plates separate and move away from each other.
What is a mid-ocean ridge?
The strongest earthquake in North America occurred in this state.
What is Alaska?
This type of stress will cause building materials to twist and fall over.
What is torsion?
This is thought to create a black hole.
What is the collapse of a very large star?
The name of the supercluster where the Milky Way galaxy exists.
What is the Virgo Supercluster.
This proved that Continental Drift Theory was correct.
What is lava spilling out of the Mid-Atlantic ridge?
The strongest type of earthquake energy wave.
What are surface waves?
The shape that is considered the strongest when put under extreme stress.
What is a triangel?
