Unit 2: Models and star patterns Flashcards
Phenomenon
Unusual events that you observe
Aurora Borealis
Glowing halo of colors around the North Pole. This is known as Northern lights
Hurricanes
Tropical weather that can travel at high speeds. In the Western Pacific there are Typhoons and in the Indian Ocean there are cyclones.
Tornadoes
Spinning air that is attached to the storm itself
Small Mass Stars
Nebula, Protostar, Main Sequence, Red Giant, White Dwarf. These stars live the longest.
Nebula
A cluster of gas that is put together by gravity
Protostar
A young star that is still gathering Mass. Depending on how much gas it takes it could be a small star or a big star.
Main Sequence Star
Longest part of a stars lifetime. This core is hot, dense, and infused with hydrogen and helium to produce energy.
Red giant
A star that is past it’s peak and expands.
White dwarf
Star is dying and uses all of it’s hydrogen fuel.
Inner Planets
Mercury, Venus, Earth, Mars. These planets are small, rocky, and closer to the sun.
Outer Planets
Jupiter, Saturn, Uranus, Neptune. These planets are called gas giants.
High Mass Star
Nebula, protostar, main sequence, red super giant, supernova, neutron star, black hole.
Red Super Giant
Huge star that runs out of fuel.
Supernova
Huge stars that explode and could go one of 2 ways.
Neutron stars
Massive star that runs out of fuel and callopses. When it callopses crashes everything together like subatomic particles.
Black Hole
Where an enormous amount of gas gets packed into a tiny hole.
Stellar Evolution
A star changes and can become a new star
HR Diagram
A diagram that can tell us the temperature and luminosity of stars
Scientific Model
A model that helps us observe an object that can’t be seen with the naked eye.
Merits
Aspects of a scientific model to represent the concept
Limitations
Aspects of a scientific model that don’t represent the concept
Patterns
Something in nature that happens repeatedly
Lumonsity
The brightness of a star
Radiate
Gives of energy like light or heat
“To scale”
Using ratio to represent if an object is small or large
