Questions and Answers

Which of the following scenarios best exemplifies the interaction between the hydrosphere and the lithosphere?

  • The erosion of a riverbed, leading to the transportation of sediment downstream. (correct)
  • The formation of clouds due to evaporation from a lake.
  • The release of oxygen into the atmosphere by phytoplankton in the ocean.
  • The absorption of ultraviolet radiation by the ozone layer in the stratosphere.

If the Earth's rotation were to slow down significantly, which of the following changes to atmospheric processes would be MOST likely to occur?

  • An increase in the concentration of greenhouse gases in the atmosphere.
  • A strengthening of the jet stream, resulting in faster air currents.
  • A decrease in the intensity of solar radiation reaching the surface.
  • A weakening of the Coriolis effect, leading to less deflection of wind patterns. (correct)

Which of the following processes primarily contributes to the transfer of heat from the Earth's surface to the upper troposphere?

  • Conduction
  • Advection
  • Radiation
  • Convection (correct)

How would increased volcanic activity, releasing large amounts of ash and gases into the atmosphere, MOST directly impact the hydrosphere?
