A star converts basic elements into heavy elements such as Iron and Carbon through a process called Nuclear Fusion.
True
False
Blue shift occurs when stars move away from the earth.
True
False
What phase of a star's lifecycle occurs when the star runs out of "normal fuel."?
The star increases in size due to instability of a large iron core and becomes a "Red Giant", and begins to burn other elements such as oxygen and xenon
The star explodes and becomes a supernova, creating a nebula and white dwarf star
The star implodes, creating a black hole
The star is created out of gas and dust from the nebula
Elements such as Carbon, Iron, and Lithium along with many others came from stars.
True
False
How are stars formed?
Neutron stars are "baby" stars that come from exploded older stars.
Black holes create the heat and pressure needed to use Nebula gas and dust to begin the formation of a star.
Hollywood
A cloud of gas and dust called a Nebula is the "cradle" for stars. Gas and dust in the Nebula come together through gravity, heat, and pressure and create a star.
Basic building blocks for the formation of galaxies, stars, and planets began with the Big Bang.
True
False
What will happen to the Sun in 400 Million years?
The sun will shrink, becoming a white dwarf star.
The sun will increase in temperature, burning more hydrogen and turning blue
the sun will grow in size as the amount of hydrogen decreases, becoming a red giant star.
The sun will implode, leaving a black hole that will destroy the solar system
