Where does air pressure go?
- A.
Air pressure goes nowhere
- B.
Air pressure always flows from areas of low pressure to areas of high pressure
- C.
Air pressure always flows from areas of high pressure to areas of low pressure
- D.
Air Pressure is too fat to go anywhere.
Correct Answer
C. Air pressure always flows from areas of high pressure to areas of low pressureExplanation
Air pressure always flows from areas of high pressure to areas of low pressure. This is because air molecules move from an area of higher concentration (higher pressure) to an area of lower concentration (lower pressure). This movement creates a pressure gradient, causing air to flow from areas of high pressure to areas of low pressure. This is the fundamental principle behind wind and weather patterns, as air moves to equalize pressure imbalances in the atmosphere.Rate this question:

What is another name for a high pressure system?
Correct Answer
Anticyclone
Cyclone
Tropical AirExplanation
An anticyclone is another name for a high pressure system. In an anticyclone, the air pressure at the center is higher than the surrounding areas, causing the air to sink and diverge outward. This creates stable and clear weather conditions. On the other hand, a cyclone is a low pressure system with air flowing inward and upward, resulting in unstable weather conditions. Tropical air refers to warm and humid air masses found in tropical regions, but it is not specifically associated with high pressure systems.Rate this question:

What are the different forces caused by the rotation of the earth called?
- A.
The Coriolis Effect
- B.
The Trade Winds
- C.
The Walker Circulation
Correct Answer
A. The Coriolis EffectExplanation
The Coriolis Effect refers to the different forces caused by the rotation of the Earth. As the Earth rotates, objects moving over its surface are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection is due to the rotation of the Earth and the conservation of angular momentum. The Coriolis Effect influences various phenomena, such as the rotation of cyclones and anticyclones, the direction of ocean currents, and the movement of projectiles. It is an important concept in meteorology and fluid dynamics.Rate this question:

Which Two Statements are Correct?
- A.
The winds go outwards and backwards in both high and low pressure systems.
- B.
The winds go inwards and upwards in a low pressure system
- C.
The winds always go the same way.
- D.
The winds go downwards and outwards in a high pressure system
- E.
The winds go downwards and outwards in a low pressure system.
Correct Answer(s)
B. The winds go inwards and upwards in a low pressure system
D. The winds go downwards and outwards in a high pressure systemExplanation
In a low pressure system, the air rises and creates a region of lower pressure. As a result, the surrounding air flows inward towards the center of the low pressure system. This inward movement of air is what causes the winds to go inwards in a low pressure system.
On the other hand, in a high pressure system, the air descends and creates a region of higher pressure. This descending air causes the surrounding air to flow outward away from the center of the high pressure system. This outward movement of air is what causes the winds to go downwards and outwards in a high pressure system.Rate this question:
-

Which way will the winds move in the Northern Hemisphere?
- A.
Clockwise
- B.
Anti Clockwise
- C.
Left
- D.
Right
- E.
Both Ways
Correct Answer
B. Anti ClockwiseExplanation
In the Northern Hemisphere, the winds move in an anti-clockwise direction. This is due to the Coriolis effect, which is caused by the rotation of the Earth. As the Earth rotates, the winds are deflected to the right in the Northern Hemisphere, causing them to move in an anti-clockwise direction around areas of low pressure. This is opposite to the direction of movement in the Southern Hemisphere, where the winds move in a clockwise direction.Rate this question:
-
- 6.
Which way do the winds move in the Southern Hemisphere?
- A.
Towards the Equator
- B.
Left
- C.
Horizontally
- D.
Clockwise
- E.
Anti Clockwise
Correct Answer
D. ClockwiseExplanation
In the Southern Hemisphere, the winds move in a clockwise direction. This is due to the Coriolis effect, which is caused by the rotation of the Earth. As the Earth rotates, the winds are deflected to the left in the Southern Hemisphere, causing them to move in a clockwise direction. This is opposite to the Northern Hemisphere, where the winds move in a counterclockwise direction.Rate this question:

C. They generally stay in the 900 hpa area.
D. Air near the centre of a low pressure system is unstable
E. Associated with unsettled weather, cloudy conditions, wind, cyclones and periods of rain.Explanation
Low pressure systems are associated with unsettled weather, cloudy conditions, wind, cyclones, and periods of rain. They generally stay in the 900 hpa area and never go above 1013 hpa. The air near the center of a low pressure system is unstable, which contributes to the formation of clouds, precipitation, and atmospheric disturbances.Rate this question:

Is this statement true for high pressure systems or low pressure systems?"Associated with constant good weather, cloudless skies and dry conditions"
- A.
High pressure systems
- B.
Low pressure systems
- C.
None
- D.
Both
Correct Answer
A. High pressure systemsExplanation
High pressure systems are associated with constant good weather, cloudless skies, and dry conditions. This is because high pressure systems are characterized by sinking air which inhibits cloud formation and leads to stable atmospheric conditions. The sinking air also prevents the formation of precipitation, resulting in dry conditions. Therefore, the statement is true for high pressure systems.Rate this question:

- E.
The closer the lines, the stronger the wind
Correct Answer(s)
A. Show lines of equal air pressure
B. Are measured in hectopascals
E. The closer the lines, the stronger the windExplanation
Isobars are lines on a weather map that connect points of equal air pressure. They are used to show areas of high and low pressure. The measurement of air pressure is commonly done in hectopascals. The closer the isobar lines are to each other, the stronger the wind is in that area. Therefore, the three correct statements are: isobars show lines of equal air pressure, isobars are measured in hectopascals, and the closer the isobar lines, the stronger the wind.Rate this question:
