INTRODUCTION
You have now completed Storms, the first part of Catastrophic Events. After each part of this module, you will be assessed on your ability to show what you know and what you can do as it relates to natural catastrophic events.
The assessment in this lesson is divided into two parts. During Part A of the assessment, you will observe a paper helix, or spiral, above a hot lamp and record your observations of the paper helix. You will be asked to describe what the helix tells you about how air moves.
For Part B of the assessment, you will be asked to complete multiple-choice and short-answer questions about tornadoes, hurricanes, ocean currents, and other weather-related events. You will review diagrams and interpret data plotted on a graph. Finally, using three weather maps, you will write a weather report and forecast the weather for your hometown. Your teacher will use the results of this assess-ment to determine how well you can apply the concepts, knowledge, and skills you have learned in the first part of the module.

Listen as your teacher describes Part A of the assessment.3.
Watch as your teacher holds the paperhelix above the lamp, as shown in Figure 8.1. Record your observations on Student Sheet 8.1a. How is the movement of the helix like the vortex of a storm?

Your teacher will distribute the questionsand the answer sheet for Part B of the assessment. Do not write on the sheet of questions. It will be used by other classes throughout the day. Your teacher will go over each part of the assessment with you.
5.
Begin the assessment when your teacherdirects you to do so.
6.
Turn in your assessment after you havefinished all the questions.

REFLECTING ON WHAT YOU’VE DONE
1.
Review your scored assessment with theteacher.
2.
Discuss with the class how you can applywhat you have learned in Storms to your daily life. Answer one or more of these questions:
A. What have you learned about weather that will help you in the things you do each day?
B. How do you think being more informed about severe weather helps reduce the risks associated with these events? C. What are the benefits of using the NOAA Weather Radio?
3.
Look at your group concept map andbrainstorming list from Lesson 1. Do you want to add anything to the list? Can you answer any of your earlier questions now? Do you have any new questions that you want to add?
activity might include shifting of the ground surface, changes in the type of gas that comes from the ground, and changes in how the ground conducts electricity. Some people even say that changes in animal behavior are a sign of earthquake activity.
As both hurricanes and tornadoes do, earth-quakes create their own risks. People who live where strong earthquakes occur are at risk. They could experience personal injury, property damage, and disruption of daily life. Risks asso-ciated with earthquakes include the destruction of buildings, the breakage of gas pipes and elec-tric lines leading to fires, and the loss of phone service and water. Earthquake hazards include Like some of the other catastrophic events that
you are studying during this module, earth-quakes have had a part in shaping and reshap-ing the earth since long before recorded history. They do so by vibration or movement of part of the earth’s surface.
When an earthquake strikes, it often does so without warning. In this way it is different from a hurricane, whose path of destruction can be monitored and often predicted. Even after an earthquake has begun, there is often no way to tell how long it will last or how strong it will be. In this way it is similar to a tornado.
Geologists are trying to determine the type of activity that means an earthquake is likely. This

cracks and gaps in the soil, land-slides, changes in the course of rivers and streams, and tsunamis. Geologists have tried to reduce the risks associated with earthquakes by mapping active faults. A fault is a fracture along a plane in the earth’s crust where there has been movement. In Parkfield, California, for
In 1994 in Los Angeles, gas from broken gas pipes burned even as water from broken water pipes flooded a street after an earthquake.

after such disasters happen, many people build and rebuild their homes and businesses. Developing policies and programs can help reduce the risks related to public safety. These include, for example, special building codes in earthquake-prone regions and organizations such as the Federal Emergency Management Agency that teach people about the dangers of
natural hazards.
QUESTION
Which natural catastrophic event would you like to study in greater detail? Prepare for Lesson 9 by making a list of your ideas. example, seismologists began monitoring activity
along the San Andreas Fault in 1980. Between 1857 and 1966, earthquakes had occurred there every 20 years or so, almost like clockwork. By setting up sensitive equipment along the fault, scientists hoped to determine the type of activity that leads to an earthquake and to increase their chances of correctly predicting the next earth-quake in Parkfield.
Scientists now know where earthquakes, vol-canoes, hurricanes, tornadoes, and floods occur most often. Although all of these natural haz-ards can bring serious risks to humans, great numbers of people continue to live in cities where such events are likely to happen. And
