Suppose the albedo of a planter is measure to be 40 percent. This means that
40% of the sun's energy is reflected
During natural processes, hear transfer is always from
warmer to cooler substances
During the Earth's orbit around the Sun, the inclination (tilt) of the Earth's axis
remains constant at 23.5 degrees
Low sun angles result in reduced solar energy bc
energy is spread over a larger area and atmospheric path length is longer
which of the following correctly describes the equinoxes?
days and nights are equal in length in all parts of the world
Flagstaff, AZ is at 35 degrees N latitude. what is the angle of the Sun's noon rays here on March 21
55 degrees
At 45 degrees S latitude, the angle of the noon sun is lowest and the length of daylight is shortest on
June 21
the energy associated with motion is called
kinetic energy
the longest wavelength on the electromagnetic spectrum are
none of these
The wavelengths emitted by the Earth are
longer than those emitted by the sun
On the average, how much of the Sun's energy that is intercepted by the Earth system is reflected to space?
30%
The length of daylight gets progressively longer going south from the equator on
December 21
The spring equinox in the Northern Hemisphere starts on
March 21
The 90 degrees angle rays strike the Tropic of Cancer on
June 21
New York City has its greatest length of daylight on
June 21
The Earth receives energy from the Sun by
radiation
The process of ____ involved the movement of a mass or substance
convection
Wind is an example of
convection
Thermals and advection are both types of
convection
The transfer of heat through matter by molecular collision is called
conduction
Scattering
is responsible for the redness of sunsets
During reflection,
light gets reflected and bent
At what time of the year is the Earth's axis not tilted either toward or away from the Sun?
autumnal equinox
The longest day of the year occurs on
June 21
The surface with the HIGHEST albedo is
snow
Wavelengths of the visible spectrum are between
0.4 and 0.7 micrometers.
The type of energy that is responsible for sunburn is:
ultraviolet
The Earth emits terrestrial radiation
only at night
If an imbalance occurs between incoming and outgoing energy at the Earth's surface
temperatures either increase or decrease
Earth is closest to the Sun during
No. hemisphere winter
Most of the solar energy absorbed by planet Earth and its atmosphere is absorbed by
the earth's surface
What happens to solar radiation as it passes through the atmosphere?
Transmission. Absorption. Atmospheric greenhouse effect. Reflection. Albedo
Which of the following gases does not absorb any portion of incoming solar radiation?
nitrogen
The atmosphere is heated primarily by
absorption of Earth radiation.
Clouds play an important role in the Earth's energy budget because they
reflect solar energy
The Stefan-Boltzman Law states that
All objects with temperatures above 0 Kelvin emit radiation
The primary factor which determines what type and how much radiation an object emits is
temperature
All radiation emitted by the Earth and its atmosphere is in the category of
infrared
The primary cause of Earth's seasons is
inclination of earth's rotation axis
Atmosphere is strongly _____ with respect to terrestrial radiation
absorptive
The atmosphere is nearly _____ with respect to solar radiation.
transparent
Early in January the Earth is closer to the Sun than at any other time of the year. This position is termed...
perihelion
The atmosphere is nearly ______ to terrestrial radiation that has a wavelength between 8 and 11 micrometers
transparent
The absorption of terrestrial radiation by certain gases in the lower atmosphere is called the
greenhouse effect
Which of the following gases is the best absorber of ultraviolet light?
oxygen
