Question

Near the top of the troposphere, what forces balance to describe the movement of air masses?

coriolos force, pressure gradient force, friction

coriolis force, friction

pressure gradient force only

coriolis force, pressure gradient force

pressure gradient force, friction

Which is the largest sink of CO2 in the Earth System (on small time scales)?

anthropogenic activity

deep ocean storage

photosynthesis

weathering

ocean-atmosphere exchange

From an infrared satellite, why might Australia (in the summer) appear different than the adjacent ocean?

desert albedo is lower than the ocean albedo; therefore it reflects less light back to space

it is warmer than the surrounding ocean; therefore it emits radiation at a longer wavelength

australia is warmer than the surrounging ocean; therefore it emits radiation at a shorter wavelength than the ocean

it is colder than the surrounding ocean; therefore it emits radiation at a longer wavelength

much of australia is light colored desert; therefore it reflects more light back to space

1) coriolis force, pressure gradient force

these two forces affect the wind directions, frictional force came in to play when wind go around large objects

2)photosynthesis

during the photosynthsis plants use atmospheric CO2 to prepare glucos in presence of sunlight, and store this in the plant body.

3)australia is warmer than the surrounging ocean; therefore it emits radiation at a shorter wavelength than the ocean.

as the temperature increases the wavelength of emitted radiation decreases.
