PHYSICAL SCIENCE 105 Earth System Assignment Provide a comprehensive yet concise response to the following ques8ons. Please place your responses on a separate sheet of paper. 1.
Mars is 140,000,000 miles from the Earth. If you traveled in an airplane travelling at 550 miles per hour, how long would it take to get to this planet? What about Saturn, which lies 790,000,000 miles away? What about Neptune, which lies at 2,700,000,000 miles away? Provide your answers in years. So for the first problem, divide 140,000,000 miles by 550 miles/hr. This yields a value but it is in hours and we wat 8me in years. So, divide your value by 8,760 (the number of hours in 1 year) and you will get your final answer. 140,000,000 miles / 550 miles/ hour = 254,545.455 hours. 245,545.455 hours / 8760 hours per year = 28 years Mars = 28.03 years Saturn = 163.97 years Neptune = 560.4 years 2.
The Voyager spacecraT is currently travelling at approximately 39,000 miles per hour. If it travelled this rate consistently from Earth, how long would it take to get the Proxima Centauri (the closest star outside our solar system; 4.25 light-years away)? (Note: 1 light year is approximately 6 trillion miles) 25.5 trillion/39,000= 653,846,154 hours 653,846,154/8760= 74,639.97 years 3.
The length of recorded history for humans is approximately 5,000 years. How does this compare with the length of geologic 8me? What percentage of 8me is represented by human recorded history? 5000/4.6 billion= 0.000001 = 0.0001% of Jme is human history
4.
Provide an example of how an event in one Earth system affects another part of the Earth system. Rain, which is from the hydrosphere, increases plant growth, which is the biosphere.
5.
Humans are part of the Earth system. List at least two examples of how you, in par8cular, influence one or more of Earth’s major spheres. We use our heaJng unit in our home, burning gas, which pollutes the atmosphere. I also create waste through use of products in my everyday life, adding to landfills & polluJng the biosphere
