U5 disasters test review.pptx
This document contains a review test over natural disruptive events such as lightning, hurricanes, tornadoes, volcanic eruptions, droughts, and more. It includes multiple choice and short answer questions testing knowledge of how these events form, their impacts, measurement scales, and key terms. For example, it asks how hurricanes are named (alphabetically), how they are ranked (based on 5 categories of wind speed), and vehicles used to monitor them (ships, satellites, airplanes).

- 1. Natural Disruptive Events Test Review (Unit 5) 2014-2015
- 2. Lightning is formedwhen excited electrons in the clouds are attracted to positive charges within a cloud, between clouds, or on the ground. What type of energy is released when this happens? light and sound
- 3. Hurricanes are formedwhen ocean temperatures exceed 80°F. What type of energy is this? Thermal (heat)
- 4. Tornado warnings areissued when tornadoes have been sighted in an area. When do you think tornado watches are issued? When conditions are right for tornadoes to form.
- 5. What effects doesa volcanic eruption have on the local environment? • Ash and dust in the air can affect plants and animals in the area • Lava flow can kill trees and other vegetation • Coral reefs can be destroyed by lava flow into the ocean
- 6. Explain why hurricane season in the Atlantic Ocean is from June to November. The ocean temperatures must be warmer than 80°F. The summer months have the warmest temperatures.
- 7. Name at least1 condition that upgrades a thunderstorm to “severe”. 1. Hail that is ¾” or bigger 2. Wind gusts greater than 58 mph 3. Tornado formation
- 8. Name at least1 condition that must be present for a hurricane to form. • Ocean temperature greater than 80°F • Winds of similar speed blowing in the same direction • Drop in atmospheric temperature as winds move upwards • Location: just north of the equator over the ocean • Dry winds blowing off the African coast
- 9. When a tropicalstorm reaches the criteria to be classified as a hurricane, it is given a name. How are hurricanes named? Alphabetically
- 10. Tropical storms areclassified as hurricanes when wind speeds reach … 74 mph
- 11. The center ofmany tropical weather patterns is called … the eye.
- 12. Which describes adrought? A.A very long period of heavy rain B.High temperatures for an extended period of time C.A large wave generated by an earthquake D.An extended period of very dry conditions D
- 13. What structure inGalveston was built to protect the island from storm surges? A.The Hotel Galvez B.The Seawall C.UTMB D.Moody Gardens E.Schlitterbahn Water Park B
- 14. Tornadoes are measured on the _____ scale. A.Seismic B.Fujita (EF) C.Richter D.Doppler E.Metric F. Category B
- 15. Hurricanes are ranked according to wind speed. How many categories are there for ranking hurricanes? 5
- 16. Hurricanes are calledby another name when they occur in the Southern Pacific Ocean, the Indian Ocean, and near Australia. What is that name? cyclone
- 17. Of all thenatural disruptive events we have learned about, which has the most widespread negative effect on Texas ecosystems? hurrican es
- 18. Name at least1 vehicle or tool scientists use to monitor hurricane activity. Ships Satellites Airplane s
- 19. Which part ofvolcanic eruptions is responsible for affecting Earth’s weather and climate? Dust and ash ejected into the atmosphere upon eruption
- 20. Cyclone: a tropicalstorm that forms in the Southern Pacific or Indian Ocean Typhoon: a storm that forms in the Northwest Pacific (near Japan) Hurricane: severe tropical storm that forms over the North Atlantic Ocean What do all these storms have in common? They all form over an ocean.
- 21. Earth’s atmosphere isfound _____________. surroundin g the planet
- 22. As severe stormscome ashore, they push large volumes of water onto the land, threatening lives, and causing flooding and property damage. What is this flood called? Storm surge
- 23. Blizzards dump enormous amounts of snow on land. What is an effect that might follow a blizzard? flooding
- 24. Tornado Alley stretchesfrom Nebraska to Texas. Why is this region prone to tornado activity? Conditions in tornado alley are favorable for tornado formation. During the summer, the plains of Middle America get very hot (creating updrafts) and there are many thunderstorms. Tornadoes form during thunderstorms, when unstable hot air near the ground rises and meets the cooler air above in the thunder clouds. Tornadoes can form at any time of the year, but most of them form from March to August (in the Northern Hemisphere). The flatter landscape allows storms to travel without mountains or other landforms to block them.
- 25. Which storms have overall stronger winds: hurricanes or tornadoes? tornadoes
- 26. Where can droughts occur? In any area and climate where there is a lack of precipitation over a long period of time.
- 27. What are the2 most destructive parts of a hurricane? wind and water
- 28. Most tornadoes occurin the late afternoon. Why? The ground is hotter because it has had more time to absorb
