Groundwater occurrence and movement has no direct influence on: a. earthquake activity b. land subsidence c. land slide potential d. hydraulic conductivity e. soil formation f. none of the above 3. In terms of Earth's water budget, groundwater ranks a. higher b. lower 4. Ultimately, the hydrological cycle is driven by: a. geothermal energy fluxes toward Earth's surface b. orographic rainfall due to abrupt changes in elevation c. solar energy fluxes toward Earth's surface d. adiabatic cooling in the atmosphere 5. In the equation below, the variable "Var" refers to: a. void ratio b. pressure head c. hydraulic conductivity d. intrinsic permeability than glaciers and ice caps: P Var = p.g

Deep water- waves with constant wavelength Wave movement Approaching shore- waves touch bottom (wavelength decreases) Surf zone (breakers form) Waves touch bottom as they encounter water depths that are less than half a wavelength C E B 00000 00000 Depth is >½ wavelength 0000 0000 Velocity decreases (wave height increases)

Activity 12.1: Wave Characteristics Pg 200 1. Refer to Figure 12.1 and select the letter that identifies each of the following.wave crestwave troughwavelengthwave heightwave base 2. Below what depth would a submarine have to submerge so that it would not be swayed by surface waves with a wavelength of 24 meters?____ mActivity 12.2: Deep Versus Shallow Water Waves Pgs 201-202Refer to Figure 12.1 to answer the following questions. 1. Do particles in deep-water waves trace out circular or elliptical paths? 2. Near the shore in shallow water, do water particles trace out circular or elliptical  3. In shallow water, are water particles in the wave crest ahead of or behind those at the bottom of the wave? 4. As waves approach the shore, do their heights increase or decrease? Do wavelengths become longer or shorter? 5. In the surf zone, is the water in the crest of a wave falling forward or standing still? 6. What is the velocity of deep-water waves that have a wavelength of 46 meters and a…
