As the magnitude of natural disasters increases their frequency of occurrence
Correct Answer
B. Decreases
Explanation
As the magnitude of natural disasters increases, their frequency of occurrence decreases. This is because larger and more severe natural disasters tend to happen less frequently compared to smaller ones. For example, major earthquakes or hurricanes are less common than smaller earthquakes or storms. This can be attributed to the fact that the conditions required for larger disasters to occur are less likely to happen frequently. Therefore, as the magnitude of natural disasters increases, their frequency decreases.
2.
What cloud form is a sign of tornado formation?
Correct Answer
A. Wall Cloud
Explanation
A wall cloud is a cloud form that is often associated with tornado formation. It is a large, lowering cloud that extends from the base of a thunderstorm. The presence of a wall cloud indicates that the storm is capable of producing a tornado. Wall clouds are typically characterized by their dark, rotating appearance and can be a warning sign for severe weather.
3.
Earthquakes are found at which three types of fault lines?
Correct Answer
B. Convergent, Divergent, Transform
Explanation
Earthquakes are found at three types of fault lines: convergent, divergent, and transform. Convergent fault lines occur when two tectonic plates collide, causing one plate to be forced beneath the other, resulting in intense pressure and earthquakes. Divergent fault lines occur when two tectonic plates move away from each other, creating a gap where magma rises to the surface, causing earthquakes. Transform fault lines occur when two tectonic plates slide past each other horizontally, causing friction and earthquakes. Therefore, the correct answer is convergent, divergent, and transform fault lines.
4.
Tsunamis are caused by:
Correct Answer
A. Seismic activity, submarine landslides, cosmic impacts
Explanation
Tsunamis are caused by seismic activity, submarine landslides, and cosmic impacts. Seismic activity refers to earthquakes that occur beneath the ocean floor, causing the movement of tectonic plates and resulting in the displacement of water. Submarine landslides can also trigger tsunamis when large amounts of sediment or rock slide down the continental slope and displace water. In rare cases, cosmic impacts such as meteorite impacts can generate tsunamis by creating huge waves in the ocean.
5.
What should you do if you are caught in the open, and a tornado is present?
Correct Answer
D. Lay in a ditch
Explanation
If you are caught in the open and a tornado is present, the safest option is to lay in a ditch. This is because a ditch provides some protection against the strong winds and flying debris associated with a tornado. By laying in a ditch, you can reduce the risk of being directly hit by debris and increase your chances of survival. Seeking shelter in a car or laying in an open field can expose you to greater danger as these options offer less protection from the tornado's destructive forces.
6.
In which direction do tornados rotate in North America?
Correct Answer
C. Both
Explanation
Tornadoes in North America can rotate in both clockwise and counterclockwise directions. This is because tornadoes are influenced by the interaction of various weather systems, including the larger-scale atmospheric circulation patterns, local wind patterns, and the topography of the region. These factors can cause tornadoes to rotate in different directions, making it possible for tornadoes in North America to rotate both clockwise and counterclockwise.

Explanation
The word "volcano" comes from the name Vulcan, who was believed to be the god of fire in Roman mythology. This is because volcanoes are known for their fiery eruptions, spewing out molten lava and ash. The association between volcanoes and fire is evident in the destructive and fiery nature of volcanic activity, making "Fire" the correct answer.
9.
What is a major cause of hurricane formation?
Correct Answer
A. Warm ocean water
Explanation
Warm ocean water is a major cause of hurricane formation because it provides the necessary energy and moisture for the development and intensification of tropical storms. As warm air rises from the ocean surface, it creates an area of low pressure, which then draws in more warm air and moisture from the surrounding area. This process continues to fuel the storm, causing it to grow stronger and potentially develop into a hurricane. Therefore, warm ocean water is a crucial ingredient in the formation and intensification of hurricanes.

If you are outdoors when an earthquake hits, move away from buildings and utility wires.
Correct Answer
A. True
Explanation
During an earthquake, buildings and utility wires can pose a significant risk to safety. Buildings may collapse or have falling debris, while utility wires can break and cause electrocution hazards. Therefore, it is crucial to move away from these potential dangers and find an open space when an earthquake occurs. This will help to minimize the risk of injury or harm caused by collapsing structures or live wires.
13.
The epicenter of an earthquake is the farthest area its vibrations reach to.
Correct Answer
B. False
Explanation
The explanation for the given correct answer is that the epicenter of an earthquake is actually the point on the Earth's surface directly above the focus or origin of the earthquake. It is not the farthest area that the vibrations reach to, but rather the point where the seismic waves originate and spread out from.
14.
Tornadoes can occur without a visible funnel.
Correct Answer
A. True
Explanation
Tornadoes can occur without a visible funnel because not all tornadoes have a visible condensation funnel. Some tornadoes may be obscured by rain, dust, or low cloud cover, making the funnel difficult to see. Additionally, tornadoes can form as a result of strong rotation within a thunderstorm, even if a visible funnel does not develop. Therefore, it is possible for tornadoes to occur without a visible funnel.
15.
The correct order of the phases of hurricane development is tropical wave, tropical depression, tropical storm & hurricane.
Correct Answer
A. True
Explanation
The correct order of the phases of hurricane development is as follows: tropical wave, tropical depression, tropical storm, and hurricane. A tropical wave is a disturbance in the tropical atmosphere, which can potentially develop into a tropical depression. A tropical depression is a low-pressure system with organized thunderstorms but lacks a closed circulation. If the tropical depression intensifies further, it becomes a tropical storm, characterized by stronger winds and a more defined circulation. Finally, if the tropical storm continues to strengthen, it reaches hurricane status, with even stronger winds and a well-defined eye at its center. Therefore, the given statement is true.
16.

_______________ is the most turbulent part of a hurricane ‘s anatomy
Correct Answer
Eyewall
Explanation
The eyewall is the most turbulent part of a hurricane's anatomy. It is a ring of intense thunderstorms that surrounds the eye of the hurricane. The eyewall is where the strongest winds and heaviest rainfall occur, making it the most dangerous and destructive part of the storm. The intense updrafts and downdrafts within the eyewall create a continuous cycle of rising warm air and sinking cold air, fueling the storm's strength and causing the violent weather conditions associated with hurricanes.
22.
_______________ scale is used to measure the intensity of a tornado.
Correct Answer
Fujita
Explanation
Fujita scale is used to measure the intensity of a tornado. The scale was developed by Dr. Tetsuya Theodore Fujita, a Japanese-American meteorologist, in 1971. It categorizes tornadoes based on the damage they cause, ranging from F0 (weakest) to F5 (strongest). The scale takes into account the estimated wind speed and the type of damage observed. It is widely used by meteorologists and researchers to assess the strength and impact of tornadoes.
23.
The tornado that forms over warm water is called a _____________.
Correct Answer
Waterspout
Explanation
A waterspout is a type of tornado that forms over warm water. It is characterized by a funnel-shaped cloud that extends from the water's surface to the base of a cumuliform cloud above. Waterspouts are typically weaker than land tornadoes but can still pose a threat to boats and coastal areas. They are commonly seen in tropical or subtropical regions where warm ocean waters provide the necessary energy for their formation.
24.
The amount of ground displacement in an earthquake is called the _________.
Correct Answer
Slip
Explanation
The amount of ground displacement in an earthquake is called the slip. Slip refers to the movement that occurs along a fault line during an earthquake, causing one side of the fault to move relative to the other. This displacement can result in the release of energy in the form of seismic waves, leading to the shaking and destruction associated with earthquakes.
