Scientists plan to take measurements to determine the epicenter of a series of moderate tremors along the Alaskan coast. Which tool would be most appropriate for the scientists to use?

• anemometer

• seismograph

• sling psychrometer

• spring scale

Volcanic eruptions are catastrophic events that can lead to loss of life. Which measure should people living near the region of an active volcano take to minimize the loss of life?

• Use seismographs to predict volcanic eruptions

• Install devices to monitor the levels of gases emitted by the volcano.

• Build houses with no vents to avoid contact with lethal gases.

• Build tall houses with steel reinforcements to withstand tremors.

A student makes an earthquake wave box to study how waves travel. He opens one surface of a cardboard box, punches a hole in the top and bottom of the box using a nail, and ties a string across the holes from top to bottom. He then attaches a few paper clips to make vibrations visible on the string. The image shows the experimental setup. The student then places the box on a wooden table, hits the table with a force, and records how the string vibrates. The student now wants to learn if waves can pass through other kinds of materials. What should be the student’s next step?

• Leave the box in the current position, and record how the string vibrates when a greater force is applied

• Place the box upside down, and record how the string vibrates when the table is hit with the same force.

• Cut open another side of the box, and record how the string vibrates when the table is hit with a greater force.

• Use a string made of a different material, and record how it vibrates when the table is hit with the same force.

Engineers use innovative technologies to reduce the impact of earthquakes. One of the technologies is shown.The isolation bearings help the building retain its original shape and not collapse when the ground moves due to an earthquake. What is the impact of using this technology widely?

• It helps reduce the loss of lives due to building collapses.

• It helps predict an earthquake before it hits a region.

• It helps make building structures earthquake-free.

• It helps reduce the cost of building structures.

A tsunami is:

• a spinning windstorm that forms over the ocean with high wind speeds.

• a series of ocean waves usually following an earthquake or volcanic eruption.

• a vibration deep within the Earth or at its surface that causes cracking and subsidence.

• when magma rises through the Earth's surface and releases tons of ash and gases.

One region of the world that is very exposed to volcanoes, tsunamis, and earthquakes is called:

• the Ring of Fire.

• the North and South Pole.

• the United States.

• Eastern Europe.

Why is it beneficial to be able to predict when and where natural hazards will occur as much as possible?

• Communities can be notified to evacuate

• So that we can stop them from happening again

• So that scientists know where to go in order to study them

• So that we can harness their power for renewable energy
