Betsy was located at what latitude and
longitude point on the above map?
270N, 750W
2. On September 6 Betsy was located at
320 N, 760 W. On September 7 Betsy
was located at 330 N, 770 W. In what
city do you predict Betsy made landfall?
Morehead
3. Predict what date Betsy made landfall.
Sept 8
4. List several possible effects of a
volcanic eruption.
Relocation of animals, burned
vegetation, and ash blocking sunlight.
5. Many times during an earthquake, fires erupt in cities near the earthquake zone. Predict what may cause
those fires to burn.
Gas lines underneath the city can break cause fuel to leak and burn
6. While watching the news you see a story about a fast moving storm that uprooted trees and snapped power
lines in a small neighborhood. None of the other surrounding neighborhoods were affected. What type of
catastrophic event is most likely responsible for this type of damage?
tornado
7. What types of catastrophic events can cause widespread flooding?
Hurricane
8. What is weathering?
The breaking down of rock into sediments
9. List several examples of mechanical (physical) weathering.
Rocks split in half by water freezing and thawing, waves crashing on rocks
10. List several examples of chemical weathering.
Acid rain dissolving rocks, rusting of rocks
11. What size of sediments is deposited first: large or small?
Large then small
12. What causes most of the erosion that occurs along the Gulf of Mexico?
Waves
13. In which Texas ecoregion is Houston located?

16. Which ecoregion would you expect to be impacted the most by hurricanes?
Gulf Coast
17. Which of the following catastrophic events is most likely responsible for large amounts of beach erosion?
Hurricane
18. Study the diagram to the right showing an island
before and after a hurricane. What most likely caused
the changes to the island seen in the diagram?
Ocean waves caused by hurricanes eroded sand from
the beaches
19. What is a possible effect of humans pumping out
too much groundwater?
The land above the groundwater will begin to sink/sinkhole
20. What happens to surface water when humans dump
chemicals and trash in it?
It becomes polluted
21. What is a possible result of humans pumping too much
groundwater out of the aquifer in the diagram to the right?
The water level in the lake will decrease
22. An area that drains to a common waterway, such as a stream, lake, estuary, wetland, aquifer, or even the
ocean, is called a(n)…
