CH. 1-3 TRUE/FALSE
Farmers use an index called the harvesting index as a guide to planting and for determining the approximate dates when a crop will be ready for harvesting.
FALSE
If more molecules are packed into an air column, it becomes denser, the air weighs less, and the surface pressure goes down.
FALSE
In most areas, the warmest time of the day about five feet above the ground usually occurs around noon.
FALSE
Occasionally, the air temperature in the atmosphere may actually decrease with height, producing a condition known as a temperature inversion.
FALSE
Radiant energy, or radiation, travels in the form of waves that move through a medium from high temperature areas to low temperature areas
FALSE
Rain often occurs at areas of high surface pressure.
FALSE
The atmosphere that originally surrounded Earth was probably similar to the air we breathe today.
FALSE
The atmospheric absorption of radiation produced by a thin layer of clouds in the upper atmosphere is popularly called the greenhouse effect.
FALSE
The concentration of oxygen varies greatly from place to place, and from time to time.
FALSE
The global balancing of the surplus of energy trapped by the Earth in the mid-latitudes with the deficit of energy in the northern and southern latitudes has little effect on our weather and climate.
FALSE
The human body's perception of temperature, called the relative body index, changes with varying atmospheric conditions.
FALSE
The term weather refers to the accumulation of daily and seasonal atmospheric events over a long period of time
FALSE
Thermometers and other instruments are usually housed in an enclosure called a weather box.
FALSE
When all other factors are the same, the faster the wind blows, the greater the heat loss, and the colder we feel. This is known as sensible temperature.
FALSE
When the solar wind encounters Earth's magnetic field, it severely deforms it into a teardrop-shaped cavity known as the magnetotail.
FALSE
Charged particles (ions and electrons) traveling through space in the form of plasma are referred to as space weather.
FALSE
Check My Work Many common sayings about the weather, such as "red sky at morning, sailor take warning; red sky at night, sailor's delight," are rooted in careful observation, and are considered to be products of the scientific method.
FALSE
During July, northern latitudes of the Northern Hemisphere have less daylight hours than in the middle latitudes.
FALSE
Earth's atmosphere is a relatively thin, gaseous envelope comprised mostly of carbon dioxide and oxygen.
FALSE
Snow is a good absorber but a bad emitter of infrared energy
TRUE
Solar wind particles interacts with our atmosphere to produce auroral displays and solar storms.
TRUE
The annual temperature ranges over interior continental land masses are much larger than those over large bodies of water.
TRUE
The cooling degree-day is used during warm weather by builders to estimate the energy needed to cool indoor air to a comfortable level.
TRUE
The heat energy required to change a substance, such as water, from one state to another is called latent heat.
TRUE
The height of the tropopause varies: it is normally found at higher elevations over equatorial regions, and it decreases in elevation as we travel poleward.
TRUE
The seasons occur as a result of the angle at which sunlight strikes Earth's surface (due to Earth's tilt) and the duration of sunlight at a particular latitude (daylight hours).
TRUE
The transfer of heat energy by atmospheric and oceanic circulations prevents low latitudes from steadily becoming warmer and high latitudes from steadily growing colder.
TRUE
This book, your body, flowers, trees, air, Earth, and the stars are all radiating a wide range of electromagnetic waves.
TRUE
We assume that volcanoes spewed out the same gases long ago as they do today creating Earth's second atmosphere composed of mostly water vapor, carbon dioxide, and nitrogen.
TRUE
A radiation inversion is more likely to occur on a clear night with very little or no wind.
FALSE
Absolute zero refers to zero degrees on the centigrade scale, the point at which water freezes at normal atmospheric pressure.
FALSE
An unseasonably warm spell around the middle of autumn is referred to as the fall equinox.
FALSE
Arthritic pain is often relieved when rising humidity is accompanied by falling pressures.
FALSE
A bimetallic thermometer consists of two different pieces of metal (usually brass and iron) welded together to form a single strip.
TRUE
Although our atmosphere extends upward for many hundreds of kilometers, it gets progressively thinner with altitude.
TRUE
Areas of high and low pressure, and the swirling air around them, are the major weather producers for the middle latitudes.
TRUE
As cooler air sinks, it becomes heated and subsequently rises, and the cycle is repeated. In meteorology, this vertical exchange of heat is called convection.
TRUE
Because of Earth's rotation, the winds are deflected from their path toward the right in the Northern Hemisphere.
TRUE
Besides carbon dioxide, other greenhouse gases include methane, nitrous oxide (laughing gas), and chlorofluorocarbons.
TRUE
Doppler radars rely on signals returning to the station after bouncing off of precipitation
TRUE
Headaches are common for local populations on days where there are hazy skies or when there is a thin, bright overcast layer of high clouds.
TRUE
In many areas of the far western United States, only sparse vegetation grows on south-facing slopes, with dense vegetation growing on the north facing slopes.
TRUE
It is not the greenhouse effect itself that is of concern, but the enhancement of it due to increasing levels of greenhouse gases.
TRUE
Longitude is considered an important control of temperature.
TRUE
Maximum and minimum thermometers are liquid-in-glass devices used for determining daily maximum and minimum temperatures, respectively.
TRUE
Objects that selectively absorb and emit radiation, such as gases in our atmosphere, are known as selective absorbers
TRUE
Potential energy is the stored energy an object has due to its mass and height above a surface.
TRUE
