This is due to the abundance of active volcanoes in these countries; hence, they are identified to be in the\_\_\_\_\_ A. Atlantic Ring of Fire B. Pacific Ring of Fire 2\. What do you call a weak to violent shaking of the ground that is produced by the sudden movement of rock materials below the earth's surface? A. earthquake B. seismic waves 3\.

A fault is a thin zone of crushed rock between two blocks of rock and can be any length, from centimeters to thousands of kilometers.

The West Valley fault which crosses from DRT, Bulacan to Calamba, Laguna is an example of\_\_\_\_\_\_ A. active fault B. inactive fault 14\. What kind of scientists can help us understand the earthquake and what instrument will he use to study the earth? A. Meteorologist and barometer B. Seismologist and seismometer 15\.

What makes it crucial for Ashlyn that she locate the earthquake\'s epicenter? A. to identify the origin of the earthquake B.to tell where the breaking of rock begins 17\. What characteristic is described if the focus of the description is the effects of the earthquake on people, structures, and the surroundings? A. intensity B. magnitude 18\. How do scientists learn about the physical properties of the Earth\'s different layers? A. They measure seismic waves and make inferences based on changes in wave speeds. B. They ask major political leaders' opinions about scientific research 19\. When the rocks suddenly snap, the stored energy is released. The released energy that can be calculated by the scientist is called\_\_\_\_ A. intensity B. Magnitude 20\. Surface waves can only travel through the surface of the Earth while the body waves such as primary and secondary waves can travel through the Earth's inner layers. A. false B. true 21\. Which of the following sequences correctly lists the different arrivals of seismic waves from **first to last**? A. Primary waves \-\-- Secondary waves\-\-- Surface waves B. Primary waves\-\--Surface waves\-\--Secondary waves 22\. S-waves can travel only in solids. Which of the following observations will prove that the outer core of the earth is molten or liquid? A. The visibility of the P-waves as they travel along the core of the Earth B. The disappearance of the S-waves as they travel along the outer core of the Earth. 23\. In which part of the Pacific Ocean is the term typhoon used? A. Northwestern Pacific Ocean B. Northeastern Pacific Ocean 24\. Which of the following best explain why Philippines is prone to typhoons? A. Philippines is a tropical country. B. Philippines is geographically located along the Pacific region near the equator 25\. Which is the correct sequence of tropical cyclone categories based on a low to high speed of the wind? A. Tropical depression -- Tropical storm -- Severe tropical storm -- Typhoon -- Super typhoon B. Tropical storm - Super typhoon -- Tropical depression -- Severe tropical- storm -- Typhoon 26\. Which of the following gives the correct meaning of PAGASA? A. Philippine Atmospheric, Geophysical, and Astronomical Services Authority B. Philippine Atmospheric, Geophysical, and Astronomical Services Administration 27\. According to PAGASA, approximately how many tropical cyclones enter the PAR each year? A. 15 B. 20 C. 25 28\. Why do tropical cyclones weaken as they hit the lands? A. More water vapor in the area B.
