1.
There are wind symbols (or "Wind Arrows") on the map. The direction that the wind blows is shown by the way the arrow is pointing, and the wind speed is shown by how many 'tails' are on the arrow. Use the legend to find out what wind speed is shown near Townsville (on the NE coast of Australia).
Correct Answer
A. 6-12 km/hr
Explanation
The wind speed shown near Townsville on the NE coast of Australia is 6-12 km/hr. This can be determined by using the legend provided on the map, where it is stated that the wind speed is shown by the number of 'tails' on the arrow. Since the wind symbol near Townsville does not have any tails, it indicates a wind speed of 6-12 km/hr.
2.
What is the wind speed shown in Port Headland?
Correct Answer
B. 33-41 km/hr
Explanation
The wind speed shown in Port Headland is 33-41 km/hr.
3.
The Earth's ___ causes air to flow clockwise around lows...
Correct Answer
A. Rotation
Explanation
The Earth's rotation causes air to flow clockwise around lows. As the Earth rotates, the Coriolis effect comes into play, which deflects moving objects, including air masses. In the Northern Hemisphere, the deflection causes air to curve to the right, resulting in clockwise circulation around low-pressure systems. This rotation is an essential factor in the formation and movement of weather systems, influencing wind patterns and atmospheric circulation globally.
4.
They are often marked on the map with ___ for high...
Correct Answer
C. H
Explanation
The correct answer is H because it is stated in the question that the marks on the map are for high. Since H is the only option that starts with the letter H, it is the most likely choice for the correct answer.
5.
The general movement of air (or ____) is from areas of high pressure to areas of low pressure...
Correct Answer
D. Wind
Explanation
The general movement of air is from areas of high pressure to areas of low pressure. This movement is known as wind. Wind is caused by the uneven heating of the Earth's surface, which creates differences in air pressure. Air moves from high pressure areas to low pressure areas to equalize the pressure, resulting in the formation of wind.
6.
The unit used to ____ air pressure is called a Hectopascal (hPa)
Correct Answer
A. Measure
Explanation
The unit used to measure air pressure is called a Hectopascal (hPa). This unit is commonly used in meteorology and is equivalent to one millibar. It is used to quantify the force exerted by the atmosphere on a given area. By measuring air pressure, scientists and meteorologists can gather important information about weather patterns, air masses, and atmospheric conditions.
7.
On the map, the isobars circle high or low pressure ____.
Correct Answer
A. Areas
Explanation
Isobars are lines on a weather map that connect points of equal atmospheric pressure. They typically form closed loops around high-pressure and low-pressure areas, indicating the regions where the pressure is higher or lower than the surrounding areas. This helps meteorologists predict weather patterns and understand the movement of air masses.
8.
These join points of equal air ___.
Correct Answer
A. Pressure
Explanation
The join points of equal air pressure are where the air pressure is the same. This means that at these points, the air molecules are exerting the same force per unit area. Therefore, the correct answer is "Pressure."
9.
The lines on the weather map are called _____.
Correct Answer
D. Isobars
Explanation
Isobars are lines on a weather map that connect points of equal atmospheric pressure. These lines help meteorologists analyze and predict weather patterns. By observing the spacing and shape of isobars, meteorologists can identify areas of high and low pressure, which are important indicators of weather conditions. Therefore, isobars are the correct term for the lines on a weather map.
10.
The symbol used to depict a cold front is
Correct Answer
B. Line with triangles
Explanation
A cold front is a boundary between two air masses, where a cold air mass is advancing and replacing a warmer air mass. The symbol of a line with triangles is used to depict a cold front on weather maps. The line represents the boundary between the two air masses, and the triangles indicate the direction in which the cold air is moving. This symbol helps meteorologists and weather forecasters identify and track the movement of cold fronts, which often bring changes in weather conditions such as rain, thunderstorms, or cooler temperatures.
