GEOG1900 CSCC Exam 1 complete
Questions and correct Answers
What are the climatic controls - correct answer-✅Latitude, continentality / oceanicity, topography
Which hemispheres are the Tropic of Cancer and the Tropic of Capricorn respectively - correct answer-
✅Cancer-North
Capricorn-South
What is an isoline - correct answer-✅a line that connects points of equal value
What is an isotherm - correct answer-✅A line that connects points of equal temperature
What is an isobar - correct answer-✅Line on a weather chart which connects areas of equal/constant
barometric pressure
What is an isohyet - correct answer-✅a line on a map connecting points having the same amount of
rainfall in a given period.
precision vs accuracy - correct answer-✅precision is consistency of output whereas accuracy is
alignment with the targeted value or goal
What are sub-solar points - correct answer-✅Place that gets directly under the sun. Only between the
tropics
Radiation - correct answer-✅is the only form of energy that transfers across open space; this is as
electromagnetic waves
Define Insolation - correct answer-✅Incoming Solar Radiation
What happens to some insolation - correct answer-✅It gets scattered
Which kind of wavelength does the Sun and Earth emit respectively - correct answer-✅Sun-short
Earth-Long
Albedo - correct answer-✅the relative brightness of a surface; the fraction of solar radiation that is
reflected. The whiter the more albedo
Specific heat / thermal capacity - correct answer-✅the amount of heat energy required to increase the
temp of a substance
Conduction - correct answer-✅Heat flow requiring physical contact
Convection - correct answer-✅heat transfer by the movement of a fluid. Typically cyclical up and down
Advection - correct answer-✅horizontal convection
homosphere - correct answer-✅generally a uniform chemical composition of constant, variant gases
and aerosols; homopause (or turbosphere) at 80 kms.
Homopause - correct answer-✅transition point between hemisphere and heterosphere
heterosphere - correct answer-✅distinct layers of gas ordered by molecular weight
Inactive gases - correct answer-✅nitrogen, argon
active gases - correct answer-✅oxygen, co2, methane
aerosol - correct answer-✅particles of solid or liquid suspended in air needed for the formation of
clouds
Troposphere - correct answer-✅The lowest layer of Earth's atmosphere where humans live and weather
happens
Stratosphere - correct answer-✅Where the Ozone is and where it warms with altitude
specific humidity - correct answer-✅the maximum amount of water vapor an air parcel can hold
dew point - correct answer-✅The temperature at which condensation begins. the temperature at which
air reaches saturation without a pressure change
relative humidity - correct answer-✅The amount of water vapor in the air at any given time is usually
less than that required to saturate the air. Expressed as a percentage.
