GEOLOGY 1500 FINAL EXAM
(FARRIS) QUESTIONS WITH
CORRECT ANSWERS!!
Why is water important? - ANSWERIt shapes our planet through weathering and
erosion and is a major key to life on earth. Water is required for life on earth.
What are the chemical properties and phases of water? - ANSWERH2o, gas, liquid,
solid
What is the water table, and what is its relationship to surface water - ANSWERAn
underground boundary between the soiul surface and the area where groundwater
saturates spaces between sediments and cracks in rocks. Surface water and ground
water are usually connected in one way or another.
What is the difference between porosity and permeability - ANSWERPorosity is the
volume of empty space in a material, and is usually expressed as a percentage.
Permeability is the degree to which pore spaces are connected.
What qualifies as a desert? - ANSWERArea that receives less than 10in of rainfall
per year and has no permanent standing water
Describe the various types of deserts and where they form. - ANSWERSubtropical
deserts- largest deserts outside of the polesEquator -0 degrees latitude Sahara,
arabian, kalahari also goes through mexico
Rainshadow desertsAreas where mountains prevent clouds from making it past
causing area behind to never recive rainfall ex californiac
Coastal deserts. Cool air over cold ocean water holds little moisture Driest desert in
america the atacam in south America
Interior deserts- Air loses moisture as it crosses continentsLand far from ocean
moisture can be arid ex gobi desert
Polar desertsAbove 66 degrees N and S latitude there is little moisture, air circulation
carries dry air to polar regions its so cold that air cant hold moisture
Describe three different types of aquifers. - ANSWERUnconfined- closes to the
surface high porosity and permeability. aquitard- low porosity and permeability
middle layer, confined- lowest
How does pumping influences groundwater? - ANSWERRemoving water from an
aquifer faster than it is being recharged causes water table drawdown.
How does pollution enter and interact with ground water and aquifer systems -
ANSWERContamination travels through groundwater in the form of a plume
