 Doppler radar shows a vertical rotating column of air with high wind speed. Which is most likely occurring? 

• the formation of a hurricane 

• the formation of a tornado 

• approaching warm front 

• approaching snowstorm 

Why is it important to monitor the atmosphere during and after natural events, such as forest fires and volcanic eruptions? 

• These events increase the amount of oxygen, which may contribute to a decrease in respiratory illness. 

• These events decrease the amount of dust, which may contribute to and increase in respiratory illness. 

• These events increase the level of harmful particles, which may contribute to an increase in respiratory illness. 

• These events decrease the amount of greenhouse gases, which may contribute to a decrease in respiratory illness 

This chart shows the relationship between temperature and altitude within each layer of Earth's atmosphere. Which comparison between layers of the atmosphere is accurate? 

• Temperature increases at high altitude in the troposphere because, unlike the other layers, it contains the ozone layer. 

• Temperature decreases at high altitude in the stratosphere because, unlike the other layers, it contains the ionosphere 

• Temperature decreases at high altitude in the mesosphere because, unlike the other layers, it contains the ozone layer 

• Temperature increases at high altitude in the thermosphere because, unlike the other layers, it contains the ionosphere.

Which weather conditions are associated with El Nino?

• increased temperature, increased precipitation

• decreased temperature, increased precipitation

• increased temperature, decreased precipitation

• decreased temperature, decreased precipitation

Which best describes El Nino?

• The water in the Pacific Ocean gets warmer than normal and causes fewer hurricanes to form

• The water in the Pacific Ocean gets colder than normal and causes more hurricanes to form.

• The water in the Pacific Ocean gets colder than normal, and the flow of the jet stream is disrupted

• The water in the Pacific Ocean gets warmer than normal, and the flow of the jet stream is disrupted.

During El Nino, what happens to the amount of precipitation a region receives?

• There is no precipitation

• The amount of precipitation increases

• The amount of precipitation decreases

• The amount of precipitation does not change
