Name a type of sand dune that could form in each of these conditions: an area with abundant sand supply and winds that blow from a constant direction, an area with bidirectional winds blowing from neighboring quadrants (such as northwesterly and southwesterly), and an area with winds that blow from varying directions
Transverse dunes form where abundant sand is blown by constant winds. Bidirectional winds can produce longitudinal dunes. If the wind direction is extremely variable, star dunes can form.

Coastal California is famous for fog and smog (fog mixed with smoke). Why is the California coast foggy/smoggy, whereas Houston, Texas, which is at similar latitude, might get occasional smog from too many cars, but fog is relatively rare?
A) Warm air in Texas rises to make clouds and not fog, whereas in California cold water from the ocean mixes with warm water from the land to generate fog. B) The ocean is warm off the Texas coast, but a cold current running offshore California generates fog when the cold, moist air is drawn ashore by a sea breeze. C) There isn't really any fog; it is all just smog from too many cars in California. D) Cold currents along the Texas coast inhibit fog, whereas the ocean is warm off California.
When water is pumped from a well it creates a cone-of-depression. What is the basic reason this sometimes causes problems?
A. it reverses the natural direction of groundwater flow B. it causes increased pressure within the aquifer C. it slows the natural rate of groundwater flow D. it causes the water table to become flat E. it causes the potentiometric surface to merge with the water table
