In the Earth’s orbit when it is FARTHEST from the Sun on the 3rd or 4th of July.

22
Q

Plane of The Ecliptic

A

two-dimensional surface in which the Earth’s orbit around the Sun occurs.

23
Q

(PERI)helion

A

The point in the Earth’s orbit when it is CLOSEST to the Sun

24
Q

Revolution

A

The Earth around the Sun. Takes 365 1/4 days to complete one cycle.

25
Q

Rotation

A

The spinning of the Earth

26
Q

Seasonality

A

The quality or fact of varying with or depending on the season or time of year.

27
Q

Tropic of Cancer

A

Latitude of 23.5° North.

28
Q

Tropic of Capricorn

A

Latitude of 23.5° South.

29
Q

Solstice

A

The Sun is at 23.5° North or South. For the Northern Hemisphere it’s on June 21 or 22 (Summer Solstice). In the Southern Hemisphere it’s December 21 or 22 (Winter Solstice).

30
Q

UV Radiation

A

A form of non-ionizing radiation that is emitted by the sun and artificial sources

31
Q

Equinox

A

Two days during the year when the declination of the Sun is at the equator.
All locations on our planet (except the poles) experience equal (12 hour) day and night.

32
Q

Earth’s Tilt

A

The angle a planet’s rotation axis makes with the plane of its orbit.

33
Q

Atmospheric Composition

A

The chemical abundance in the earth’s atmosphere of its constituents including nitrogen, oxygen, argon, carbon dioxide, water vapor, ozone, neon, helium, krypton, methane, hydrogen and nitrous oxide.

34
Q

Electromagnetic Spectrum

A

The quantity of radiation that is emitted from a body

35
Q

Range of Visible Light

A

The human eye can view, the human eye can detect wavelengths from 380 to 700 nanometers.

36
Q

Role of Water Vapor in the Atmosphere

A

The most important greenhouse gas in the atmosphere

37
Q

Solar Constant

A

The average quantity of solar insolation received by a horizontal surface at 1370 Watts per square meter.

38
Q

Greenhouse Effect

A

The trapping of the sun’s warmth in a planet’s lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface.

39
Q

Short Wave Radiation

A

Wavelength between 0.1 and 0.7

40
Q

Long Wave Radiation

A

wavelength between 0.7 and 100

Unstable toxic gas formed from oxygen having three atoms in its molecule (O3).

43
Q

Montreal Protocol

A

Treaty signed in 1987 by 24 nations to cut the emissions

44
Q

Thematic Map

A

The geographical distribution of one phenomenon or the spatial associations

45
Q

Prime Meridian

A

The location from which meridians of longitude are measured.

46
Q

Circle of Illumination

A

A line that bisects areas on the Earth receiving sunlight and those areas in darkness. Cuts the spherical Earth into lighted and dark halves.

47
Q

Constant Gases

A

The gas constant is the constant of proportionality that relates the energy scale

48
Q

Inert Gases

A

A gas that does not readily undergo chemical reactions with other chemical substances and therefore does not readily form chemical compounds

49
Q

Time Zone

A

A zone on the terrestrial globe that is approximately 15° longitude wide and extends from pole to pole and within which a uniform clock time is used.

50
Q

Conduction, Convection and Radiation

A

Conduction-
Consists of energy transfer directly from atom to atom and represents the flow of energy along a temperature gradient.
Convection-
The movement of a gas or a fluid in chaotic vertical mass motions because of heating.
Radiation-

51
Q

Albedo

A

Is the reflectivity of a surface.

52
Q

Structure of The Atmosphere

A

The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are…
1. the troposphere
2. the stratosphere
3. the mesosphere
4. the thermosphere.
5. the exosphere.

53
Q

Hypoxic Conditions and Fish

A

Unable to sustain life, these areas, called dead zones, may cause die-offs of fish, shellfish, corals, and aquatic plants.
