Physical Geology 101 1 27. Running Water I (p. 424-436; 440-444) Hydrosphere How much of the Earth s surface is covered by water? ________ Earth's water is collectively called the _________________ and is stored in a number of so-called _________________ as follows: 1. ____________________ 2. ____________________ 3. ____________________ 4. ____________________ 5. ____________________ 6. ____________________ 7. ____________________ Most of the world s water is in the oceans (i.e. most water is salty). How much? ________ The second largest accumulation of water, about 2.1%, is stored in ________________ In other words, about 74% of the world s fresh water supply is ________________ Out of all the liquid fresh water we have, about 99% of it is stored ________________ Although very little of the Earth's water flows through rivers, running water is the most important geologic process for modifying the Earth's land surface. Huge volumes of water move through Earth's rivers each year. The constant shifting or recycling of water from the oceans, to the atmosphere, to the continents, and back to the oceans is called the ______________________. On a local scale there may be sudden fluctuations, such as floods or droughts. Individual reservoirs may also have prolonged changes due to global climate changes. The processes by which water travels between the reservoirs include: ___________________: water changes from a liquid to a gas, driven by the Sun's energy ___________________: water taken up by plant roots then moves into the atmosphere ___________________: atmospheric water vapor changes into a solid or liquid ___________________: condensed water that falls to the ground (rain, snow or hail) ___________________: water that is transported across the land surface (e.g. in rivers) ___________________: water that seeps into the ground The amount of time that water molecules spend in any reservoir is called the: _________________________ What is the residence time in the following reservoirs? Oceans and ice sheets: ____________________

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
