Chapter 2 - Insolation and Temperature Flashcards
Incoming solar radiation through shortwaves is termed as ________
Insolation
Long-wave electromagnetic radiation in the form of heat emitted from the earth’s surface and atmosphere
Terrestrial Radiation
In the polar regions, the heat gain is less that the heat loss. Hence this region is known as ________
Region of deficit heat
The energy which make things or objects hot
Heat
Distribution of temperature across the latitudes over the surface of the earth is called
Horizontal distibution
Lines connecting points that have equal temperatures
Isotherms
A wind system involving a huge convection current between continent and ocean
Monsoon
As one ascents in the atmosphere, steadily decreasing temperatures are encountered. This decrease of temperature with higher altitudes in the air is known as ________
Vertical Temperature Gradient
Term that refers to the rate at which temperature varies in the vertical
Lapse Rate
When two objects of unequal temperature come in contact with each other, heat energy flow from the warmer object to the cooler object, this process of heat transfer is known as ________
Conduction
Zone that receive the maximum annual insolation
Tropical region
The angle of incidence formed by the sun’s ray with the tangent of the earth’s circle at a point is called
Angle of incidence
Process by which solar energy reaches the earth and loses the energy to outer space
Radiation
Transfer of heat by movement of a mass substance from one place to another, generally vertical.
Convection
Movement of air masses from one region to another
Advection
Indicates the relative degree of heat of a substance
Temperature
Winds in the tropics, they generally come from the east
Trade Winds
Difference between average temperatures of warmest and the coldest month is known as ________
Annual range of temperature
Lapse rate of nonrising air is referred to as ________
Environmental Lapse Rate
Type Lapse Rate which involves temperature changes due to the rising or sinking of an air parcel
Adiabatic Lapse Rate
The tropical receives maximum amount of insulation and gradually decreases
True
The longer the path of the sun’s rays, the greater is the amount of reflection and absorption of heat by the atmosphere
True
Shorter duration of day leads to receipt of less insolation
true
When the source of heat transmits heat directly to an object through heat waves, it is known as terrestrial radiation
True
Atmosphere is transparent shortwaves and opaque to long waves
True
All objects hot or cold emit radiant energy continuously
True
Hotter objects radiate moe energy than colder objects
True
Air is a poor conductor of heat
True
Heating of air leads to expansion
True
In the polar regions heat gain is less than heat loss
True
