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
