Earth Space Essay
Earth Space Science Mid-Term Essay
Questions
1. Describe the three types of map projections. How are they made and which is the best for which application? 2. You see lumps of ice the size of meatballs falling from the sky. What form of precipitation are you seeing? Explain how it formed. What proof do scientist have that it formed this way? 3. What do the inner planets have in common? What is one unique characteristic of each planet? Explain your answer. 4. Define apparent magnitude and absolute magnitude. Two stars are same size and same distance from earth, but one has a higher apparent magnitude than the other. Explain why. 5. Why is Hydrogen important to a star? How does helium form? Why might an old star have a greater percentage of helium than a younger star?
Answers 1. –If you wrapped a cylinder paper around a lighted globe and traced the outlines of continents, oceans, parallels, and meridians[Cylindrical Projection]
-a projection made by placing a sheet of paper against a transparent, lighted globe such that the paper touches the globe at only one point [Azimuthal projection]
-a projection made by placing a paper cone over a lighted globe so that the axis of the cone aligns with the axis of the globe [conic projection] 2. I am Seeing Hail. Updraft convection currents carry the raindrop back into freezing cloud regions, where layer after layer of supercooled water is added to the frozen. The scientist have proof of this because if you cut it in half you can see the layers 3. –They are all Terrestrial planets
Mercury- Closest to the sun
Venus- has an orbital period of 225 days
Earth- Has water
Mars- Has history of water 4. Apparent magnitude: is the brightness as seen from earth
Absolute magnitude: is the actual brightness of a star
One star is brighter because it is brighter
