During the year 2003, the number of earthquakes that occurred was higher than usual. The map shows the locations of some of these earthquakes. Which question does the information on this map help answer?

• How often do earthquakes happen?

• When will the next earthquake happen?

• Where are earthquakes likely in the future?

• What will be the strength of the next?

Tornadoes and flooding are two natural hazards that affect parts of the United States. The map combines data showing the locations where tornadoes were reported in the spring of 2019 and the places where flooding was expected in 2019. Circle the letters of all of the statements that are supported by the data.

• The data show that tornadoes cause flooding.

• The risk areas for tornadoes and floods overlap in many places.

•      The areas where major floods were expected are the areas where the highest number of tornadoes were reported.

• The risk for major floods is affected by geologic features as well as by weather.

•      Floods and tornadoes both have similar risk areas because both hazards share some of the same underlying causes.

After studying many factors in the environment, a scientist developed this graph to predict changes in human population and natural resources. What is the role of science in this study?

• To develop government policies to reduce the use of resources

• To set costs for natural resources according to their availability

• To predict the effects of human population on natural resources

Natural events, such as volcanoes, trapped gas in ice, and decaying plants, have added CO2 to the air. Humans burning coal since the early 1800s has also added CO2 to the air. The graph shows the amount of carbon dioxide in the atmosphere for the past 800,000 years. Which statement is supported by the data in the graph and the information in the paragraph?

• The CO2 levels increased when humans began to burn fossil fuels

• CO2 levels have increased in the past 200 years because of volcanic activity

• The CO2 levels at 200,000 years ago are greater than the levels at 400,000 years ago

A man has a new job that requires him to move to one of four places: Hawaii, Maine, Texas, or Wyoming. The man wishes to live in an area at low risk for earthquakes. This United States map shows the probability of seismic activity that could result in earthquakes. Based on this map, where should the man move for his new job?

• The southeastern part of the state of Texas

• The northeastern portion of the state of Maine

• The easternmost island in the state of Hawaii
