In which layer of the Sun is energy
made? ?
The Core
In order for nuclear fusion to occur,
conditions must be extremely ______ and
________.
Hot and dense
Describe how the Sun makes energy.
The Sun makes energy through nuclear fusion in which hydrogen
atoms combine to form helium.
Name the three layers of the Sun’s
“atmosphere”.
Photosphere, chromosphere, and
the corona
What are sunspots?
They are areas on the photosphere that are cooler than the rest of the photosphere,
so they appear darker. They are areas of intense
magnetic activity.
Stars are formed from a cloud of gas and dust called a
__________.
Nebula
The type of object that a star becomes when it dies depends
the star’s ________.
mass
A star spends most of its life in this stage.
Main sequence
After the super red giant phase, a very
high mass star erupts in an explosion called
a _________
Supernova or hypernova
Name the three objects a star might become when it dies.
Black dwarf, neutron star, black hole
Name three shapes that galaxies can
have.
Elliptical, spiral, and irregular
Put these structures in order from
smallest to largest: universe, star,
galaxy, solar system
Star, solar system, galaxy, universe
What object is located at the center
of many galaxies (including ours)?
A supermassive black hole
In what part of our galaxy is Earth
located?
In one of the outer spiral arms
What is the galaxy that is closest to
ours?
Andromeda
Define mass and weight.
Mass is the amount of matter in an object;
weight is the amount of gravitational force pulling on an object.
Define volume.
Volume is the amount of space an object
takes up.
Define density.
Density is a measure of how compact something
is; it is the amount of matter within a specfic
amount of space.
What is the densest known space object?
A black hole.
If a baseball has a mass of 145 g on Earth, what is its
mass on the International Space
Station?
145 grams
Because of the Big Bang, galaxies are doing
this.
Moving away from each other
About how long ago did the Big Bang
occur?
About 14 billion years ago
What two conditions are in balance to create the Earth’s
orbit around the Sun?
Gravity and the inertia of the Earth’s
velocity
Which of the following objects
exerts a gravitational pull:
Earth, the Sun, a lab table, a spider
They all do. If something has mass, it
has gravity.
Name two factors that affect the
gravitational pull between two objects.
The mass of each object and the
distance between them.
