Star Formation
What element are stars made of?
Hydrogen
What are red giants?
A very large star with high luminosity and low surface temperature?
How old are the oldest stars?
Oldest stars are about 12 billion years old.
Primary waves or pressure waves.
What is a plate boundary?
Most geological activities take place at plate boundaries.
When hydrogen is used up, what does the star's core doto make the temperature increase?
What is Hubble's Law?
Is a way to calculate the rate of the expansion of the universe.
How does S-waves happen and what do they only travel through?
Move up or down or slide to side, perpendicular to direction of travel, S-waves travel only through solids.
How do divergent plate boundaries happen?
magma rises beneath the continent causing it to become thinner, break, and fall apart.
The universe begins to cool, stars begin to form as gravity pulled dumps of matter together.
When the temperature is high enough, what heavier elements does helium turn into?
how can cosmic Background Radiation happen?
Energy left over from the big bang, calculates the age of the universe.
What do S-waves stand for?
Secondary waves or shear waves.
What are convergent plate boundaries?
When plates converge (come today).
Why do stars burn at their core?
The pressure at the center of a star heats up the core to extreme temperatures of millions of degrees.
What are the two layers of fusion at the core?
The Inner core in helium and the outer core is hydrogen.
How can Huddle's Law be used?
Can be used to calculate age.
How does P-waves happen and what do they do in denser material?
Move in compression/expression type motion, P-waves move faster in the denser material.
What are the results when convergent plate boundaries come together
Results in mega generation and earthquakes.
