Northern hemisphere winter
The process of ________ involves the movement or circulation of a mass or substance. 1. radiation 2. conduction 3. convection 4. kinetic energy
convection
Objects with higher temperatures: 1. emit only shortwave radiation. 2. emit more shortwave radiation than cooler objects do. 3. emit most of their energy in the form of longwave energy. 4. radiate less total energy than cooler objects radiate.
emit more shortwave radiation than cooler objects do.
Low sun angles result in reduced solar energy because: energy is spread over a larger area. Sun - Earth distance is greater. absorption is reduced. day lengths are shorter.
energy is spread over a larger area.
Based on the analemma (in your book), what is the approximate location of the solar declination on August 26? 10° N 10° S 23.5° N 18°N
10° N
Suppose the albedo of a planet is measured to be 40 percent. This means that: 1 60 percent of the Sun's energy is reflected. 2 40 percent of the Sun's energy is absorbed. 3 40 percent of the Sun's energy is reflected. 4 more energy is reflected than absorbed.
40 percent of the Sun's energy is reflected

The transfer of thermal energy from one material to another by direct contact is conduction covection radiation avection
conduction
The primary cause of Earth's seasons is: changes in atmospheric thickness. varying orbital speed. tilt of Earth's rotation axis, which causes sun angles and daylight length to vary. regular changes in radiation emitted by the Sun. varying distance from the Sun, which changes how much radiation Earth receives from the Sun.
tilt of Earth's rotation axis, which causes sun angles and daylight length to vary.
