Newton’s second law of motion
The “force exerted on an object equals its mass times the acceleration produced” is a description of: Buys-Ballot’s law the isobaric law hydrostatic equilibrium a biology question Newton’s second law of motion Answer: Newton’s second law of motion Answer: Newton’s second law of motion

Lines connecting points of equal pressure are called:

The friction of fluid flow is called:

in the early morning around midnight in the afternoon just after sunset just before sunrise Answer: in the afternoon Answer: in the afternoon

An instrument used to measure wind speed is called a (an):

in a wavy pattern from west to east
The jet stream flows: directly from west to east directly from east to west from the equator toward the poles in a wavy pattern from west to east in a variety of directions depending on airplane traffic Answer: in a wavy pattern from west to east Answer: in a wavy pattern from west to east

During a major El Niño event:
Peruvian fishermen harvest a record number of fish near Christmas time. extensive ocean warming occurs over the tropical Pacific the Northeast trade winds increase in strength California experiences severe drought conditions refugees from costal countries enter the United States illegally Answer: extensive ocean warming occurs over the tropical Pacific Answer: extensive ocean warming occurs over the tropical Pacific

The majority of the United States lies within this wind belt:

Fronts are associated with:
poor self-esteem negative feedback high pressure political pressure low pressure Answer: low pressure Answer: low pressure

In winter, thunderstorms are most likely to form along:
warm fronts stationary fronts cold fronts occluded fronts cornfields Answer: cold fronts Answer: cold fronts

The development or strengthening of a middle latitude storm system is called:

An upper-level pool of cold air that has broken away from the main flow is called:
a shortwave a wave cyclone a lee-side low a cut-off low a tragedy Answer: a cut-off low Answer: a cut-off low

Developing low pressure areas generally have _____ air near the surface and _____ air aloft. diverging, converging converging, diverging converging, converging diverging, diverging conducting, convecting Answer: converging, diverging Answer: converging, diverging

The least accurate forecast method of predicting the weather two days into the future during changeable weather conditions usually is the: trend method prediction by weather types persistence forecast numerical weather prediction analogue method Answer: persistence forecast Answer: persistence forecast

A weather warning indicates that:
the atmospheric conditions are favorable for hazardous weather over a particular region hazardous weather is likely to occur within the forecast area during the next 24 hours hazardous weather is either likely or imminent or occurring within a forecast area road conditions are expected to be impassable for the entire time of the warning. hazardous weather is frequently observed in a particular region. Answer: hazardous weather is either likely or imminent or occurring within a forecast area Answer: hazardous weather is either likely or imminent or occurring within a forecast area

When making a forecast, a meteorologist typically examines __________.
surface charts upper-air charts radar displays satellite imagery all of the above Answer: All of the above Answer: All of the above

there is a chance of tornadoes tomorrow
A weather watch would probably be issued for which of the following conditions? there is a chance of tornadoes tomorrow Presently, extremely high winds are occurring at mountain summits A tornado has been sighted at the outskirts of town heavy snow has been falling over the forecast area a parade is scheduled in town on Friday Answer: there is a chance of tornadoes tomorrow Answer: there is a chance of tornadoes tomorrow

Which forecasting method assumes that weather systems will move in the same direction and at the same speed as they have been moving? persistence forecast probability forecast climatological forecast weather type forecast steady state (trend) forecast Answer: steady state (trend) forecast Answer: steady state (trend) forecast

may or may not show skill
An accurate forecast: never shows skill requires complex computer equipment always shows skill may or may not show skill is aired on the local evening news Answer: may or may not show skill Answer: may or may not show skill

All thunderstorms require ________.
rising air Divergence of the air aloft surface heating hot, humid air lifting along some barrier such as a mountain or front Answer: rising air Answer: rising air

The initial stage of an ordinary thunderstorm is the __________.

Ordinary thunderstorms only last about one hour and begin to dissipate when:
lightning neutralizes all the electrical charge in a cloud when all the precipitation particles in the cloud turn to ice when solar heating at the ground begins to decrease when the downdraft spreads throughout the cloud and cuts off the updraft. none of the above Answer: when the downdraft spreads throughout the cloud and cuts off the updraft. Answer: when the downdraft spreads throughout the cloud and cuts off the updraft.

An ordinary thunderstorm is a:
scattered or isolated storm that is not severe thunderstorm that does not produce lightening or thunder thunderstorm that has a tilted updraft and downdraft thunderstorm that does not produce hail figment of the imagination Answer: scattered or isolated storm that is not severe Answer: scattered or isolated storm that is not severe
