6 Rank your top 3 questions A. How do solar systems form? To elaborate, what are the physical processes that take place such that a number of planets gather together and begin to orbit around a sun. If they lacked rotational movement initially would they not all just be sucked into the sun's gravity straight in. Assuming they had rotational movement initially, what force caused their initial orbiting? B. Neptune and Pluto's orbits cross- will they ever collide? What would the consequence of a collision be? C. What will happen if the Moon disappear? D. How did we get to glaciation and how did we come out of it? E. Why are the first planets solid and the next one are gaseous? Since they are difference in composition, number of moons, etc what makes them planets? Can a planet have no moon? What about no sun? F. How did life began? Where did the first bacteria come from? How did it develop? G. What role do various elements play in the structure and function of earth? For example, what would be different if there were no iron? H. Although much of earths complexities have been discovered by new computer technology, such as the existence of tectonic plates, the study of minerals, seismic imaging; my question is what is inside/beneath earth, more specifically what exists beneath the ocean after all the sand and accumulation of oils and dirt? I. Is it possible for humans to survive on Mars

7 Rank your top 3 questions A. What is the reason behind the fact that gas-giant planets rotate faster than telluric planets? B. How are gaz planets formed as opposed to terrestrial planets? Will they become terrestrial in the futur, or into something different? C. Formation or the major events of our system? for example or more specifically How was the Asteroid belt between Mars and Jupiter formed or were there used to be a planet? Also Kuiper belt Comets what are they and how are they formed, also the explaination of their orbits. D. Sun converts mass and create energy in the form of heat. In that process, does the gravitational force of the sun changes as the mass of the sun changes? E. The question that I am most curious about regarding our own planet is that of the inner workings of it. Specifically, how the inner cores inflluence the movements of the mantle and surface, which in turn results in the formation of volcanoes and mountains. F. What generates the earth's magnetic field and how does it benefit us? G. If a heavy meteorite hit earth and had been absorbed by earth, would the gravity on earth change? H. Is it possible that our class can do some observing of our planetary system? Is it impossible in a city like Montreal? I. Is there any life or possibility of life on other planets in our Solar System and how did life begin on Earth?

8 Rank your top 3 questions A. How can we effectively track and protect the earth from asteroid collisions. B. Assuming that carbon-based lifeforms are not the only ones that are possible, how would we be able to detect another lifeform, or planet capable of supporting "life", if we don't really know what those lifeforms would need to exist? C. What's happening in the earth's interior? Are processes happening in the interior of the earth affecting the surface? D. why are the planets in our solar system so different? E. What causes gravity? F. What is the approximate life-span of planet Earth, or any other planet in our Solar System(or even the Sun)? Is it possible to measure/calculate this? G. What is it about earth that helps sustain life, that isn't seen on other planets? Furthermore, how specific is the exact mix of components that are integral for the sustainment of life? H. Why do planets rotate around the Sun in the same direction and at the same level? I. When will the West Coast of the United States (particularly Los Angeles) will be completely submerged due to plates tectonic?

9 Rank your top 3 questions A. Our planetary system is always shown with all the planets aligned on one plane (ie. the alignment is flat). Is this accurate? If so, why are all our planets aligned like this? Does this pattern extend out to our galaxies? To our Universe? B. How does Earth's interior work, and how does it affect the surface? C. Are there any hidden planets in our solar system that we have not yet discovered? D. How did the earth evolve from the origin into the current form? E. How was the first animal (living creature with perception) created? Whether the egg or the chicken came first? F. How does the Sun affect our climate on Earth? G. Can we predict when the next meteor will impact Earth or other nearby planets? If so how should we respond? H. How did Earth become a planet that was suitable for people to live? I. How will a gravity well created by a celestial body affect other celestial bodies around?
