Unit 7 Weather and Climate

A weather balloon is launched to collect data in the atmosphere. Which of the following sets of instruments, and their corresponding measurements, would most logically be attached to the balloon?

• A thermometer measuring temperature, a barometer measuring pressure, and a hygrometer measuring humidity.

• A speedometer measuring wind speed, a voltmeter measuring voltage, and a seismometer measuring earthquakes.

• A hydrometer measuring water density, a spectrometer measuring light, and an accelerometer measuring movement.

• A thermometer measuring pressure, a barometer measuring humidity, and a hygrometer measuring temperature.

What happens to a weather balloon as it ascends in the atmosphere?

• It expands due to the decrease in external atmospheric pressure.

• It contracts as it gets colder.

• It releases gas, causing it to shrink.

• It is compressed by the surrounding air.

Compare and contrast the movement of cold fronts and warm fronts. How does each affect the weather? Choose the statement that best summarizes the differences.

• Cold fronts move faster and produce rapid temperature and weather changes, while warm fronts move more slowly, causing gradual temperature increases and prolonged precipitation.

• Warm fronts move faster and produce rapid temperature and weather changes, while cold fronts move more slowly, causing gradual temperature increases and prolonged precipitation.

• Both cold and warm fronts move at the same pace and lead to similar weather effects.

• Neither cold fronts nor warm fronts significantly affect weather patterns.

What is a stationary front and what happens when it is over an area?

• It is a boundary between two air masses that remains stationary, often leading to prolonged rainy weather.

• It is a rapidly moving cold front that causes sudden changes in weather.

• It is a high-pressure system that stabilizes atmospheric conditions.

• It is a tropical front that brings continuous heavy rainfall.

A student observes wispy, high-altitude clouds in the sky. Identify the type of clouds and their weather implication.

• Cirrus clouds; they indicate fair weather with a potential change

• Cirrostratus clouds; they indicate an overcast sky

• Cumulus clouds; they indicate good weather

• Nimbostratus clouds; they indicate continuous rain

Convection currents influence weather patterns on Earth by transporting heat and moisture.

• They transport heat and moisture.

• They create stable atmospheric layers.

• They cause no physical changes.

• They only influence ocean currents.
