Marine west-coast climates are NOT
A) mild climates with a small annual temperature range. B) plentifully moist year round. C) found in places like Kodiak, Alaska. D) commonly found in low latitudes.
Which of the following is not a typical stage in the evolution of a Basin and Range type region?
A) Water erodes the mountains and deposits sediment in the adjacent basins. B) Sediment slowly moves downhill to the sea where it is ultimately deposited. C) Alluvial fans and bajadas form along the mountain fronts. D) Salt flats or playas and occasional playa lakes form.
The amphoteric reaction between two water molecules is endothermic, which means that this reaction requires the input of energy in order to proceed: Energy + H2O + H2O ? H3O+ + OH- The warmer the temperature of the water, the more thermal
energy is available for this reaction, and the more hydronium and hydroxide ions are formed. Based on this information, should the value of Kw be expected to increase, decrease, or stay the same with increasing temperature? A) The value of Kw will stay the same since it is a constant. B) The value of Kw will decrease since there are more hydronium ions than hydroxide ions. C) The value of Kw will increase since the rise in temperature allows for a higher concentration of both ions. D) The value of Kw will decrease since there are more hydroxide ions than hydronium ions.
Which of the following describes the air at the surface around a strengthening low-pressure area, and aloft, above the system?
