Total questions: 18
Worksheet time: 28mins
What happens to a star at the end of its life?
It explodes
The star forms an iron core. Running out of fuel and explodes.
The star explodes and forms a blackhole.
A black hole swallows it.
What emerges from a star when it is exploding?
Neutrinos
Gold, Uranium, and Iron
Space Dust
Hydrogen
Up to how long does it take for a supernova to explode?
Milliseconds
Hours
A week
4 days
When the energy production of a star stops, what does gravity do to it?
collapse the core
cause it to spin rapidly
shed the outer layers
produce a blue light
When our sun dies, it will leave behind a white dwarf star composed of the elements:
hydrogen and helium
silicon and oxygen
carbon and oxygen
iron and nitrogen
How long will the sun keeping fusing hydrogen?
10 million years
19 billion years
7 trillion years
10 billion years
What's the first type of Supernova?
The red super giant Antares has a companion star, Antares B, that is thought will contribute to a Type 1a supernova event in the coming years. However, the exact timing of the supernova is unknown. Antares is more than 880 times bigger than our Sun and thus the explosion is expected to be quite an event, but it is a great enough distance away from Earth to pose no threat.
Binary stars are two stars that orbit the same point. One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter. Having too much matter causes the star to explode, resulting in a supernova.
The type of supernova occurs at the end of a single star’s lifetime. As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but it does not have enough mass to become a supernova.
What happens when gravity causes stars to die out with a BANG.
A black hole forms
A giant shockwave made of hot air and gasses
An Iron ball
True or False- Black hole from from supernovas all the time?
True
False
How do black holes form?
After the star explodes there is leftover matter that becomes super dense to make the black hole
They jus happen
Form when gravity cause big stars to die out with a BANG
True or False- Is the odds of a black hole swallowing the earth one in one trillion?
True
False
True or False- Betelguese is near the end of its life?
True
False
What holds a star together
Hope and Faith
Gravity and Pressure
Star Dust
The gas in the star.
How is a star formed?
When the atoms are under enough pressure for their nuclei to undergo fusion.
From the matter of another nearby Supernova.
Space Dust
When did NASA launch the first orbiting telescope?
June 2012
October 1987
February 1700
June 2014
True or False-Black Holes go around swallowing stars and planets.
False
True
Can a Black Hole continue to grow?
Yes, by absorbing mass surrounding it
No, it'll never keep growing.
Yes, by pulling stars into the black hole.
No, it'll pull planets it and just destroy them
What is the difference between Supernovae and Black Holes.
There is no differnce
A supernova is a star collapsing and exploding while a Black Hole can be the result of a supernova's matter is compressed.
Matter of a star becomes super dense.
