1.
This weather instrument measures air pressure.
Correct Answer
B. Barometer
Explanation
A barometer is a weather instrument that is specifically designed to measure air pressure. Air pressure is an important factor in determining weather conditions, as it can indicate whether the weather is likely to be fair or stormy. A barometer typically consists of a sealed tube filled with mercury or aneroid capsules that can expand or contract based on changes in air pressure. By measuring these changes, a barometer can provide valuable information about the current and future weather patterns.
2.
This type of weather instrument measures air temperature.
Correct Answer
E. Thermometer
Explanation
A thermometer is a weather instrument that measures air temperature. It consists of a glass tube filled with a liquid, usually mercury or alcohol, that expands or contracts with changes in temperature. As the liquid expands, it rises up the tube, indicating a higher temperature, and as it contracts, it lowers, indicating a lower temperature. This allows meteorologists and scientists to accurately measure and monitor air temperature, which is an important factor in understanding and predicting weather patterns.
3.
This type of weather instrument measures wind direction.
Correct Answer
A. Wind vane
Explanation
A wind vane is a weather instrument specifically designed to measure wind direction. It consists of a rotating arrow or pointer that aligns itself with the direction of the wind. This allows meteorologists and weather enthusiasts to determine the origin of the wind, which is crucial for understanding weather patterns and predicting changes in weather conditions. Unlike other options such as a barometer, rain gauge, anemometer, or thermometer, a wind vane is specifically designed for measuring wind direction.
4.
This type of weather instrument measures winds speed.
Correct Answer
D. Anemometer
Explanation
An anemometer is a weather instrument specifically designed to measure wind speed. It is equipped with cups or blades that rotate when wind blows, and the rotation speed is directly proportional to the wind speed. By measuring the rotation speed, an anemometer can accurately determine the speed of the wind. Therefore, an anemometer is the correct answer for this question.
5.
This type of instrument measures the amount of precipitation.
Correct Answer
C. Rain gauge
Explanation
A rain gauge is a type of instrument specifically designed to measure the amount of precipitation, such as rainfall or snowfall. It is typically a cylindrical container with markings or a measuring scale to indicate the amount of precipitation collected. By using a rain gauge, meteorologists and weather enthusiasts can accurately measure and record the amount of rainfall in a given area, which is crucial for monitoring weather patterns and predicting potential floods or droughts.
6.
This type of instrument measures North, South, East, or West.
Correct Answer
A. Wind vane
Explanation
A wind vane is an instrument that is used to measure the direction of the wind. It consists of a pointer that moves with the wind and indicates the direction in which the wind is blowing. The wind vane is designed to align itself with the wind, allowing for accurate measurement of the wind direction. Therefore, it is the correct instrument to use when measuring North, South, East, or West.
7.
This type of instrument measures in degrees Celsius, Fahrenheit, and kelvin.
Correct Answer
E. Thermometer
Explanation
A thermometer is the correct answer because it is the instrument specifically designed to measure temperature, which is typically measured in degrees Celsius, Fahrenheit, and kelvin. A wind vane measures wind direction, a barometer measures atmospheric pressure, a rain gauge measures rainfall, and an anemometer measures wind speed.
8.
This type of instrument measures in miles per hour.
Correct Answer
D. Anemometer
Explanation
An anemometer is a type of instrument that measures wind speed in miles per hour. It is specifically designed to measure the velocity of the wind, making it the correct answer for this question. A wind vane measures wind direction, a barometer measures atmospheric pressure, a rain gauge measures rainfall, and a thermometer measures temperature.
9.
These two instruments measure in centimeters or inches.
Correct Answer
C. Barometer and rain gauge
Explanation
Barometer and rain gauge are the correct instruments that measure in centimeters or inches. A barometer measures atmospheric pressure, which is often expressed in units of centimeters or inches of mercury. A rain gauge, on the other hand, measures the amount of rainfall in centimeters or inches. Both instruments provide measurements in the specified units, making them the appropriate answer to the question.
10.
This type of instrument measures in degrees Fahrenheit.
Correct Answer
E. Thermometer
Explanation
A thermometer is the correct answer because it is a type of instrument that measures temperature in degrees Fahrenheit. This device is commonly used to measure body temperature, weather conditions, or the temperature of various objects or substances. It typically consists of a glass tube filled with a liquid, such as mercury or alcohol, that expands or contracts based on temperature changes. The temperature is then read from a scale on the thermometer, usually in degrees Fahrenheit or Celsius.
11.
In what direction does a wind point?
Correct Answer
B. Where the wind is coming from
Explanation
Wind direction is defined by the direction from which the wind originates. For example, a north wind blows from the north to the south. This is a standard convention used in meteorology and navigation.
