Explanation: According to the given image, the excerpt from “Black Hole Beginnings” that would best support the image in a multimedia presentation is option A. This is because, as more stuff gathers, its
combined gravitation grows stronger
and they are attracted to each other which is illustrated in the image.
What question should readers asked to determine the effect in the sentence?
What question should readers ask to determine the effect in the sentence?
How much stuff is combined? Where does the stuff gather?
What is the effect of a star up to nine times the mass of the sun running out of fuel?
In “Black Hole Beginnings,” what is described as an effect of a star up to nine times the mass of the sun running out of fuel?
It goes supernova
. It turns into a black hole.
What must be present for scientists to detect black holes?
The black holes in the Universe do not emit any detectable type of light. However, astronomers can still find them and learn a lot about them. They do this by measuring
the visible light, X-rays and radio waves emitted
by material in the immediate environment of a black hole.
What is described as the cause of gas and dust forming into a star?
Stars form when regions of dust and gas
in the galaxy collapse due to gravity
. Without this dust and gas, stars would not form.
What words are used in cause and effect?
- Conjunctions. The most important conjunctions are because, as, since, and so. “ …
- Transitions. The most important transitions are therefore, consequently, and as a result. …
- Prepositions. The most important prepositions are due to and because of.
How do you determine cause and effect relationships?
To find cause and effect relationships, we look for
one event that caused another event
. The cause is why the event happens. The effect is what happened. Sometimes there can be more than one cause and effect.
What happens when a star comes to an end?
When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant. While most stars quietly fade away, the supergiants destroy themselves in a huge explosion, called
a supernova
. The death of massive stars can trigger the birth of other stars.
What will be the final stage in the Sun’s life cycle?
A planetary nebula
is the final stage of a Sun-like star. As such, planetary nebulas allow us a glimpse into the future of our own solar system. A star like our Sun will, at the end of its life, transform into a red giant. Stars are sustained by the nuclear fusion that occurs in their core, which creates energy.
What happens when the Sun turns into a red giant?
In approximately 5 billion years, the sun will
begin the helium-burning process
, turning into a red giant star. When it expands, its outer layers will consume Mercury and Venus, and reach Earth. … When stars morph into red giants, they change the habitable zones of their system.
Can we detect black holes?
Scientists can’t directly observe black holes
with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. … We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby.
How did Einstein predict black holes?
Over a century ago, Albert Einstein predicted that
the gravitational pull of black holes were so strong that they should bend light right around them
. Black holes don’t emit light, they trap it; and ordinarily, you can’t see anything behind a black hole.
Why is a black hole black?
A black hole is a region of spacetime where
gravity is so strong
that nothing—no particles or even electromagnetic radiation such as light—can escape from it. … In many ways, a black hole acts like an ideal black body, as it reflects no light.
Is Earth in a nebula?
The Earth was formed from the nebula that produced the Solar System
. It is almost universally accepted that the Sun, the planets and their satellites, the asteroids, and the comets of the Oort ‘cloud’ grew from a cloud of gas and dust that contracted under its own gravity.
What does the inside of a nebula look like?
Inside a nebula probably looks
just as dark, with occasional hues of color around visible stars
. Like a cloud; think of flying through a cloud in a airplane vs. looking up at one from the ground. It’s the same effect on galaxies.
What causes a nebula?
A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from
the gas and dust thrown out by the explosion of a dying star, such as a supernova
. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called “star nurseries.”
