Origin of the Universe and Solar System
1
Includes all of space, time, matter, and energy. This means every star, planet, galaxy, and even us right here on Earth.
2
The theory proposes that the universe undergoes a series of expansions and contractions, essentially a cycle of "Big Bangs" and "Big Crunches."
3
A mid-20th-century theory suggests the universe is eternal and unchanging, with new matter continuously created to fill the gaps from its expansion, maintaining constant density.
4
Phenomenon that occurs when there is a change in the frequency or wavelength of a wave in relation to an observer who is moving relative to the source of the wave. This effect can be observed in sound and light waves, and even radio waves.
5
Is our cosmic “neighborhood”. It consists of the Sun, eight planets, their moons, and various other celestial objects like asteroids and comets.
6
Solar System theory that suggests that the Sun and planets formed from a large cloud of gas and dust (a "nebula") that collapsed under gravity, with the Sun at the center and planets forming from the remaining material.
7
Solar System theory that proposed that the Solar System formed from the gradual accumulation of smaller particles. Dust and rocks collided and stuck together, eventually forming planets.
8
Solar System theory that Suggests that a star passed close to the Sun, causing material stayed in orbit, cooled, and turned into small bodies called planetesimals, which later collided to create planets and other bodies of the Solar System.
9
Theory of the Solar System that suggest that the origin of the sun is that the central collapse of the Nebula formed the Sun.
10
Theory of the Solar System that suggest that the origin of the Sun assumes the Sun already existed or formed alongside the planets.
11
Theory of the Solar System that suggest that the origin of the Sun formed from material ejected due to tidal forces caused by a close encounter with a passing star.
12
Theory of the Solar System that suggest that the origin of the planets are form from material remaining from the gas and dust "nebula"
13
Theory of the Solar System that suggest that the origin of the planets are form from dust and rocks collided to form larger bodies.
14
Theory of the Solar System that suggest that the origin of the planets are form from materials ejected by the Sun condensed into planetesimals and later planets.
15
Which planets are composed mostly of heavier elements, smaller size, formed close to the sun where high temperatures were well suited for rock and metal condense?
16
Which planets are composed mostly of lighter elements, bigger size, formed far to the sun where low temperatures enough for ice condensation, so their overall density is lower?
17
How did ancient Greek philosophers perceive our solar system?
18
How did Copernicus’s and Galileo’s studies change the model of the solar system?
19
What is the order of the planets in the solar system, starting from the one closest to the Sun?
20
Why Earth is Able to Support Life, While Other Planets in the Solar System Cannot:
21
Medium-sized main sequence yellow dwarf star at the center of our solar system.
22
Which are the Sun´s layers?
23
Sun Layer that is the innermist layer, with high temperature, composed primarly of hydrogen and helium, is where nuclear fusion takes place. The function is the source of the Sun´s energy:
24
Sun Layer that is hot, where energy is transferred outward through radiation, meaning photons (light particles) are absorbed and re-emitted by particles, as very slow process. The function is transport slowly the energy from the core to de surface
25
Sun Layer that is less dense than the radiative zone and is where convection currents occur. The function is transfers the energy vía convenction currents.
26
Sun Layer that is the outerlayer. The function is Emits ultraviolet radiation and contributes to solar activity and affects the space waether.
28
A galaxy that measures about 100,000 light-years across. That bright streak across the middle of the night sky is made up of about several billion stars in our galaxy.
29
The inner planets are:
30
The outer planets are:
31
Huge chunks of irregularly shaped rocks, mostly located in an area between Mars and Jupiter.
32
“Dirty snowballs” made of dust, rock particles, frozen gases, and ice that are orbiting the sun, usually with enormous orbits.
33
Small pieces of rock and dust (such as disintegrated comets):
34
Meteoroids become _______ when they enter the earth’s atmosphere and burn from all of the atmospheric friction into a bright streak
35
A meteor that makes it to Earth without burning up in the atmosphere is called a ________.
36
What is a Hertzprung-Russell Diagram?
37
A large cloud of gas and dust:
38
Over the time, gravity draws the nebula together. A condensing nebula is known as a _________
39
As a medium-sized star converts its hydrogen to helium, it loses energy and cools. The core contracts, raising temperatures, while the outer layers expand, cool, and are ejected into space. A star in this phase is called a _____.
40
Large stars form ________. When the core of the giant becomes incredibly hot from all of the compression it begins fusion again.
41
A large main sequence star will expand outward to become a __________.
42
What causes a supergiant to become a supernova?
43
Different stars give off different amounts of energy, which affects the _____ of emitted light.
44
Stars at higher temperatures usually emit ____-colored light.
45
A dense remnant of a supernova collapses itself and explote, composed mostly of neutrons in its core.
46
The force of gravity sucks everything nearby in so strongly that not even light can scape, forming a _____________
47
After a giant uses all of its helium, it forms a dense, hot core called ____________
48
After a giant uses all of its helium, it forms a dense, hot core called ____________
49
When a white dwarf cools and stops emitting light, it becomes a _________
