Questions and Answers
- 1.
Where do hurricanes form?
- A.
On Lakes
- B.
Over The Ocean
- C.
On Land
- D.
On Islands
Correct Answer
B. Over The OceanExplanation
Hurricanes form over the ocean because they require warm, moist air to fuel their development. The warm ocean water provides the necessary energy for the hurricane to intensify and grow. As the warm air rises, it creates an area of low pressure, and surrounding air rushes in to fill the void. This process continues, causing the storm to rotate and strengthen. Once a hurricane makes landfall, it begins to weaken due to the loss of warm ocean water as its energy source. Therefore, hurricanes primarily form over the ocean.Rate this question:

What event can cause much damage from the shaking of the Earth's crust?
- A.
Hurricane
- B.
Tornado
- C.
Thunderstorm
- D.
Earthquake
Correct Answer
D. EarthquakeExplanation
An earthquake can cause much damage from the shaking of the Earth's crust. Earthquakes occur when there is a sudden release of energy in the Earth's crust, resulting in seismic waves that shake the ground. These vibrations can cause buildings and infrastructure to collapse, landslides, tsunamis, and other destructive effects. Unlike hurricanes, tornadoes, and thunderstorms, which primarily cause damage through wind and precipitation, earthquakes specifically result in shaking and ground displacement, making them the correct answer for this question.Rate this question:

What happens when hot and cold water meet?
- A.
The Hot Water Floats On Top
- B.
The Cold Water Floats On Top
- C.
The Two Mix Equally
- D.
The Hot Water Disappears
Correct Answer
A. The Hot Water Floats On TopExplanation
When hot and cold water meet, the hot water floats on top. This is because hot water is less dense than cold water. As water is heated, its molecules move faster and spread out, causing the water to expand and become less dense. On the other hand, cold water has slower-moving molecules and is more dense. Therefore, when hot and cold water are combined, the less dense hot water rises to the top while the denser cold water sinks to the bottom.Rate this question:
