Often in in front of a warm front (before it gets there) the weather is ______.
-
Dry and clear due to limited cloud cover and winds that blow away all of the clouds from the cold front just ahead.
-
Rainy due to increased low level moisture that rises over the warm front and is carried ahead .
-
Warmer than after the warm front passes
-
Colder than after the warm front passes
-
choice b, possibly c
-
Choice a, possibly d
Correct Answer
A. choice b, possibly cExplanation
Often in front of a warm front (before it gets there) the weather is rainy due to increased low level moisture that rises over the warm front and is carried ahead. This is because warm fronts typically bring in warmer air, which can hold more moisture. As the warm air rises over the colder air ahead of the front, it cools and condenses, leading to the formation of clouds and precipitation. Additionally, the warm air can also bring in unstable atmospheric conditions, further enhancing the chances of rainfall. Therefore, the weather in front of a warm front is often characterized by rain. It is also possible that the weather is warmer than after the warm front passes, as the warm air is advancing and replacing the colder air.Rate this question:

Within cumulonimbus clouds, ____________.
-
Thunder is the sound lightning exceeding the sound barrier inside and outside the cloud.
-
Downdrafts ideally push the hot air down because it is less dense and easier for the wind to circulate
-
Warm air is lifted in updrafts and cold air is cycled down in downdrafts, which can lead to precipitation on the surface if the cycle is broken.
-
A and e
-
Dense cold air rises and is warmed by the sun at the top, causing it to fall in the form of rain or sometimes snow.
-
A and c
Correct Answer
A. A and cExplanation
Within cumulonimbus clouds, thunder is the sound of lightning exceeding the sound barrier inside and outside the cloud. Warm air is lifted in updrafts and cold air is cycled down in downdrafts, which can lead to precipitation on the surface if the cycle is broken.Rate this question:

Stationary fronts occur when
-
A warm front slams into a cold front and their opposite momentums cause them to stop
-
The wind dies down enough to cause a front to lose its momentum
-
An occluded front disappears
Correct Answer
A. The wind dies down enough to cause a front to lose its momentumExplanation
Stationary fronts occur when the wind dies down enough to cause a front to lose its momentum. This means that the air masses on either side of the front are no longer moving in opposite directions, resulting in the front becoming stationary. The opposing momentums of a warm front slamming into a cold front would actually cause the front to continue moving, not stop. An occluded front disappearing does not necessarily result in a stationary front.Rate this question:

A warm front can typically be associated with ________.
-
Cloud cover
-
Inversion
-
Warm air replacing cold air at the surface
-
Warmer surface temperatures
-
All of the above
Correct Answer
A. All of the aboveExplanation
A warm front is a boundary between warm and cold air masses, and as it moves, it brings changes in weather conditions. It is typically associated with cloud cover because warm air rising over cold air creates condensation and cloud formation. Inversion can also be associated with a warm front, as it occurs when a layer of warm air is trapped above a layer of cooler air, causing temperature inversion. Warm air replacing cold air at the surface is another characteristic of a warm front, as the warm air mass moves in and pushes the colder air out. Lastly, warmer surface temperatures are commonly observed when a warm front passes through an area.Rate this question:

A meteorologist is mapping the station model for his region. He indicates that the temperature in Albany, NY is 40 degrees Fahrenheit with winds southwest at 30 mph on his station model- evident by 3 full tic marks on the wind vane. The dew point is set at 37 degrees F and the partly cloudy city is denoted on his model by shading in 1/2 of the model. The wind is blowing to the Northeast and his arrow is pointing to the Southwest.He did not make an error in labeling the Station Model for Albany.
-
True
-
False
Correct Answer
A. FalseExplanation
The meteorologist did make an error in labeling the Station Model for Albany. The wind direction is indicated by the direction the arrow is pointing, which is to the Southwest. However, the wind direction is stated to be blowing to the Northeast. This is contradictory information and indicates an error in labeling the station model.Rate this question:

The air is frigid cold and dry. Which air mass is it from?
-
CP
-
MP
-
CT
-
AP
-
MC
-
CA
Correct Answer
A. CAExplanation
The air mass is identified as cA because it is described as frigid cold and dry. The "c" in cA represents continental, indicating that the air mass originated over a landmass rather than an ocean. The "A" in cA signifies that the air mass is very cold. Therefore, cA is the most suitable choice based on the given description.Rate this question:

Cold front
-
None of these
Correct Answer
A. Stationary frontExplanation
The given diagram represents a stationary front. A stationary front occurs when warm and cold air masses meet but neither advances. In the diagram, the "^" symbol represents warm air rising, while the "_" symbol represents cold air sinking. The "^" and "_" symbols alternating in the diagram indicate that warm and cold air masses are not moving, suggesting a stationary front. Therefore, the correct answer is a stationary front.Rate this question:

The Troposphere _______.
-
Is the most dense
-
Is the least dense
-
Is the warmest of the first 5
-
Is where the jet stream is ( in tropopause)
-
Is where the ozone layer is (in tropopause)
-
A and d
-
All but b
Correct Answer
A. A and dExplanation
The troposphere is the lowest layer of the Earth's atmosphere and is where weather occurs. It is characterized by decreasing temperature with increasing altitude and contains the majority of the Earth's air mass. The troposphere is the most dense layer of the atmosphere because it is closer to the Earth's surface where air molecules are more tightly packed. Additionally, the jet stream, a fast-moving, narrow air current, is located within the troposphere. Therefore, options "a" and "d" are correct as they both describe characteristics of the troposphere.Rate this question:

It is quicker flying to New York from Los Angeles.
-
True
-
False
Correct Answer
A. TrueExplanation
Flying from Los Angeles to New York is quicker compared to other modes of transportation such as driving or taking a train. This is because flying allows for a direct and non-stop journey, resulting in a shorter travel time. The distance between the two cities is approximately 2,451 miles, and a flight can typically take around 5-6 hours, depending on factors like weather conditions and flight speed. On the other hand, driving or taking a train would require significantly more time, often taking several days to complete the journey. Therefore, the statement is true.Rate this question:

The ozone layer is a thick layer of O3 that, over the last 30 years, has been damaged by CO2 and CO (among many others) primarily from human activity, with factors such as excessive idling and fossil fuel incineration adding to the chaos.
-
True
-
False
Correct Answer
A. FalseExplanation
The explanation for the given answer (False) is that the ozone layer is primarily damaged by substances such as chlorofluorocarbons (CFCs) and not by CO2 and CO. While CO2 and CO are greenhouse gases that contribute to climate change, they do not directly harm the ozone layer. The ozone layer depletion is mainly caused by human-made chemicals like CFCs, which were commonly used in aerosol sprays and refrigerants. Excessive idling and fossil fuel incineration may contribute to air pollution and climate change, but they do not directly affect the ozone layer.Rate this question:

The Antarctic circle's ozone levels have been increasing at an alarmingly fast rate over the last 30 years.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false because the ozone levels in the Antarctic circle have been decreasing, not increasing, over the last 30 years. This is due to the presence of ozone-depleting substances in the atmosphere, such as chlorofluorocarbons (CFCs), which have caused a hole in the ozone layer over Antarctica. The decrease in ozone levels is a cause for concern as it leads to increased ultraviolet (UV) radiation reaching the Earth's surface, which can have harmful effects on human health and the environment.Rate this question:

The majority of the air is made of carbon dioxide and argon.
-
True
-
False
Correct Answer
A. FalseExplanation
The explanation for the answer "False" is that the majority of the air is actually made up of nitrogen (about 78%) and oxygen (about 21%). Carbon dioxide and argon make up only a very small percentage of the air, with carbon dioxide being present in trace amounts (about 0.04%) and argon accounting for less than 1%. Therefore, the statement that the majority of the air is made of carbon dioxide and argon is incorrect.Rate this question:
