Term
What was there at the begging of the solar system? |
|
Definition
Carbonaceous chondrites (primitive materia), dust and gas |
|
|
Term
What material was made during the big bang? |
|
Definition
Hydrogen, helium, lithium, and beryllium Only the very small particles. |
|
|
Term
Where did the larger elements come from? |
|
Definition
The center of stars. Stars are so large that the materials at their center are under so much pre assure that the atoms break apart and combine into larger elements. Stars are element forming factories. |
|
|
Term
What is the one thing that MUST happen for a solar system to form? |
|
Definition
A star must explode. Supernova We need the material from their cores and the supernova jump starts the star forming process. |
|
|
Term
What does iron 60 have to do with super nova? |
|
Definition
Iron 60 is radioactive and it only forms in stars. So the fact that we still see iron 60 in meteorites tells us that there must have been quite a bit at the beginning of the solar system and it must have all come from a supernova. |
|
|
Term
|
Definition
The process of small objects coming together to build larger objects and those objects coming together to build larger object |
|
|
Term
Density within the solar system. |
|
Definition
As you move away from the sun the density of objects in our solar system decresses because the material that is solid at higher temperatures is more dense. As the temperature decreases lighter materials can be solid so planets and moons can be made out of them. |
|
|
Term
How is Jupiter like it's own solar system? |
|
Definition
The densities of the moons of Jupiter decrease as you move away from Jupiter and Jupiter has it's own snow line. |
|
|
Term
|
Definition
318 times the size of earth. One of the two top 100 objects in the solar system. It has two tidally heated moons. It gives structure to the steroid belt. It takes objects from the Kuiper belt and throws them in to the inner solar system as comets and out to the Oort cloud. It sent the asteroid that killed the dinosaurs. |
|
|
Term
|
Definition
Ice is the most abundant material in the solar system. Right at the snow line there is a huge leap in the amount of material available to make planets out of. Jupiter is the first planet past the snow line so there is a lot of material to make it out of. |
|
|
Term
|
Definition
At the very early stages of solar system formation Jupiter amassed a massive core of ice and rock. Once it was large enough, Jupiter could hold onto the hydrogen and helium being pushed out of the solar system by the sun. Jupiter just kept gatheringnand gathering material. |
|
|
Term
Which is Jupiter more like and why, a star or a inner solar system planet? |
|
Definition
A stare. Because it is made up of massive amounts of hydrogen and helium like stars. |
|
|
Term
Jupiter is 318 times as massive as the earth. Why isn't it 318 times the size (radius)? |
|
Definition
Jupiter is just about as large as a large planet can get. Just like the mountains on mars, jupiter cannot get any larger because the material at it's center crumbles under the pressure of more material. |
|
|
Term
What would happen if you continue to add more and more material to Jupiter? |
|
Definition
Eventually the pressure at the center would get so high that the atoms them selves would break apart and join into larger atoms. The heat from this would cause Jupiter to glow like a star. |
|
|
Term
The Kuiper belt has not accreted into a single object because it takes too long to accrete that far from the sun. Why then have neptune and Uranus accreted if they too are far away from the sun? |
|
Definition
Neptune, Uranus and Saturn did not accrete at their present locations. They formed much closer to the snow line, right near Jupiter and then moved further out. |
|
|
Term
|
Definition
Description of the dynamic (lots of movement) history of the solar system. When the planets formed they were close to the snow line. When jupiter and Saturn got into 2:1 resonance they wreacked havoc on the rest of the solar system. |
|
|
Term
What 4 events does the Nice Model explain. |
|
Definition
The current location of the outter solar system planets Late heavy bombardment The Oort Cloud. The Kuiper Belt |
|
|
Term
How does the Nice Model explain late heavy bombardment? |
|
Definition
When Jupiter and Saturn were in 2:1 resonance with each other They threw some of the loos material around them into the inner solar system where it collided with the inner planets causing late heavy bombardment. |
|
|
Term
How does the Nice Model explain the Oort Cloud? |
|
Definition
When Jupiter and Saturn were in 2:1 resonance with each other some of the loose material was thrown out to form the Oort cloud. |
|
|
Term
How does The Nice Modle explain the Kuiper Belt? |
|
Definition
When Jupiter and Saturn were in 2:1 resonance with each other the left over material made the Kuiper Belt. |
|
|
Term
Why is water important on earth? |
|
Definition
It allows for plate tectonics and we need it to live. |
|
|
Term
Was there water in the inner solar system when the earth formed? |
|
Definition
No. Based on the density gradient and the snow line water could not start in the inner solar system. |
|
|
Term
Where did the water come from that is on earth and how did it get to us? |
|
Definition
It has to have come from the outer solarsystem. It was part of carbonaceous chondrites that Jupiter sent to earth. So in a sence Jupiter sent the water that supports life on earth |
|
|
Term
What is the future of the solar system? |
|
Definition
The sun will balloon out into a red giant. It will be so large that the planets in the inner solar system will be burnt up and the snow line will be pushed out. |
