What would happen to Earth's atmospheric temperature if the amount of incoming shortwave radiation from the Sun decreased and was less than the longwave radiation lost to space?
Atmospheric temperature would decrease.
What would happen to Earth's atmospheric temperature if the amount of shortwave radiation reflected at Earth's surface increased significantly?
Atmospheric temperature would decrease.

Atmospheric temperature would increase.
What would happen to Earth's atmospheric temperature if the amount of shortwave radiation reflected by clouds decreased significantly?
Atmospheric temperature would increase.
What would happen to Earth's atmospheric temperature if the amount of incoming shortwave radiation from the Sun was the same as the longwave radiation lost to space?
Atmospheric temperature would remain the same.

How does the inclination of Earth's axis (relative to the plane of its orbit) change over the course of a year?
The inclination of Earth's axis does not change.
External Heat Engine
powered by the sun that drives the earths fluid envelopes ( ex: the atmosphere and hydrosphere)
Only some shortwave radiation from the Sun reaches Earth's surface. What is the leading cause of this radiation loss?
reflection by clouds
Albedo
reflectivity
If a home uses a large supply of solar panels to generate electricity, but has no battery system, surplus electricity that is produced is usually __________.
released into the power grid for others to use, generating a credit to the homeowner
Closed system
system shut off from surrounding environment -self contained in that energy and or matter does not enter or leave the system
T
temperature
Which of the following is a challenge to using solar-generated electricity in places not connected to a power grid?
the lack of efficient and inexpensive battery technology

Which of the following statements about Earth's solstices is correct?
The December solstice is the time of year when Earth's geographic South Pole is leaning most directly toward the Sun.
Which of the following would indicate that a home is using solar power to generate electricity and is NOT using batteries?
There are solar panels on the roof and power lines going to the home.
What characteristic best describes the areas with the lowest levels of reflected shortwave radiation in both June in the Northern Hemisphere and December in the Southern Hemisphere?
areas of open water Water's ability to absorb energy along with the high Sun angles during the respective high-sun seasons in each hemisphere contribute to the low levels of reflected shortwave radiation.
