Where are the days and nights of equal length all year long?
At the equator
When it is January and winter in the Northern Hemisphere, it is ____ and ____ in the Southern Hemisphere.
January; summer
Water heats up ____ and cools off ____ than land.
More slowly, more slowly
Two objects, A and B, have the same mass but the specific heat of A is larger than B. If both objects absorb equal amounts of energy,
B will become warmer than A
The wind-chill factor:
Relates body heat loss with wind to an equivalent temperature with no wind
The sun is directly overhead at Mexico City (latitude 19°N):
Twice a year
The primary cause of a radiation inversion is:
Infrared radiation emitted by the earth's surface
The maximum in daytime surface temperature typically occurs ____ the earth receives its most intense solar radiation.
After
The main reason(s) for warm summers in middle latitudes is that:
The sun is higher in the sky and we receive more direct solar radiation, The days are longer
The lowest temperature is usually observed:
Around sunrise
The latitude at which there is a yearly balance between incoming and outgoing radiation is about ____.
37 DERGREES
The largest annual ranges of temperatures are found:
At polar latitudes over land
The lag in daily temperature refers to the time lag between the:
Time of maximum solar radiation and the time of maximum temperature
The earth is tilted at an angle of 23.5° with respect to the plane of its orbit around the sun. If the amount of tilt were increased to 40°, we would expect in middle latitudes:
Hotter summers and colder winters than at present
The deepest radiation inversion would be observed:
In polar regions in winter
Suppose yesterday morning you noticed ice crystals (frost) on the grass, yet the minimum temperature reported in the newspaper was only 35°F. The most likely reason for this apparent discrepancy is that:
Temperature readings are taken in instrument shelters more than 5 feet above the ground
Radiational cooling typically occurs:
At night
Over the earth as a whole, one would expect to observe the smallest variation in temperature from day to day and from month to month:
231/2o north latitude (tropic of cancer)
On a clear, calm night, the ground and air above cool mainly by which process?
Radiation
More solar radiation is received at the:
At the surface
Longer days are generally associated with:
More rain fall
Lines connecting points of equal temperature are called:
Isotherms
Incoming solar radiation in middle latitudes is less in winter than in summer because:
A and b only
the tilt of the earth on its axis.
