Variations in solar insolation

How is the lower atmosphere primarily warmed?

• Direct absorption of solar energy.

• Energy radiated upward from the Earth's surface.

• Heat generated by human activities.

• Convection currents from the upper atmosphere.

During the daily cycle, when does the maximum atmospheric temperature typically occur relative to the peak solar radiation?

• At the same time as peak solar radiation.

• Several hours before peak solar radiation.

• Several hours after peak solar radiation.

• At sunrise.

Which factor contributes to high latitudes absorbing less solar energy compared to low latitudes, given an equal amount of incoming solar energy?

• The higher concentration of solar energy at high latitudes.

• The higher angle of incidence of sunlight at high latitudes.

• The increased reflection of solar energy due to higher albedo from snow and ice.

• The shorter path sunlight travels through the atmosphere at high latitudes.

What is the net energy balance in the atmosphere at low latitudes compared to high latitudes?

• Net loss of heat at low latitudes and net gain at high latitudes.

• Net gain of heat at low latitudes and net loss at high latitudes.

• Equal energy balance at all latitudes.

• Net gain of heat at both low and high latitudes.

• II'm starting to get this.

• I feel like there is more to know.
