Heat is a measure of the average kinetic energy possessed by molecules. is synonymous with temperature. is a transfer of energy from areas with high temperatures to those with low temperatures. measures the total kinetic energy in a substance.

is a transfer of energy from areas with high temperatures to those with low temperatures.

The energy associated with motion is called: 1. kinetic energy. 2. potential energy. 3. vibrational energy. 4. molecular motion energy.

kinetic energy.

The wavelengths emitted by the earth are: 1. shorter than those emitted by the Sun. 2. shorter than those emitted by the Sun. 3. longer than those emitted by the Sun. 4. about the same as those emitted by the Sun except when the Sun is experiencing sunspots.

longer than those emitted by the Sun

Earth is closest to the Sun during: 1. Southern hemisphere autumn. 2. Southern hemisphere winter. 3. Northern hemisphere winter. 4 Northern hemisphere summer.

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

Earth's rotational axis maintains polarity (points in the same direction) throughout the year. One-half of Earth is illuminated at all times during the year. The line between the two halves is called the 1 Albedo 2 Plane of Ecliptic 3 Circle of illumination 4 Solstice

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.
