GEOG 2050 Chapter : Chapter 2 Notes
Document Summary
Inner planets: milky way galaxy, solar system, speed of light, gravity, solar system formation, sun, solar radiation, evolution of the atmosphere, solar radiation, fusion, solar wind. Insolation: universe forms about 13. 5 to 15 billion years ago. Big bang theory: milky way galaxy. And 10. 1 billion years ago: speed of light = about 300,000 km/sec (186,000 miles/sec, light year = about 10 trillion km (about 6 trillion miles) Gravity: attractive force between objects with mass, responsible for: Tides and more: rotating solar system begins to form from dust and gas about 4. 6 billion years ago. Heavier materials clump near center to form innermost proto-planets. Lighter materials coalesce near periphery to form outer planets. Earth forms out of iron, nickel, manganese, and silicates. Insolation: rotation, revolution, subsolar point, equilibrium, solar constant, seasons, axial tilt, axial parallelism, sphericity, subsolar point, tropics of cancer/capricorn, arctic/antarctic circles, solstice/equinox, midnight sun, mercury. About 14 c (-89 c to 57. 7 c)
