b. Coastal flooding
c. Regional climate change
d. Buildings toppled by shaking ground
11. Farmers in the middle section of the country grow crops that feed many people. Suppose that
over a period of several years, the region receives far less rainfall than normal, reducing the size

13. Richter Scale for Earthquakes
Magnitude
1-2
3-4
5
6
Effects
Not felt, but recorded on seismographs
Felt, but causes no damage
Felt by most people, minor damage
Damage to weakened buildings or other weak
structures within 10 km from epicenter
7
Major damage to structures within 100 km of
epicenter
8
Very destructive injury or loss of life possible
over a range of several hundred kilometers
9
Extremely rare and very destructive; damage
may reach as much as 1000 km from epicenter
An earthquake occurs in the United States. People as much as 150 km away feel the shaking
caused by the earthquake, but major damage to buildings and other structures is limited to an
area within 80 km of the epicenter. The magnitude of the earthquake is -a. 5
b. 6
c. 7
d. 8
14. While walking along a beach, you observe a large pile of sand near a row of rocks. The next
day, the pile of sand is gone, and the sand that remains appears wet. The disappearance of the
large sand pile is the result of -a. Chemical weathering
b. Mechanical weathering
c. Erosion
d. Deposition
15. Which event probably would not occur as a result of an earthquake?
a. Tsunami occurring across the ocean
b. F4 tornadoes forming near the epicenter
c. Mountains near the epicenter getting taller or shorter
d. Temporary equilibrium at the fault
16. Why is Texas a prime target for hurricanes that can cause catastrophic damage?
a. Texas is a very large area
b. Texas lies in the path of hurricanes that move in from the Atlantic Ocean
c. Texas borders a large area of warm water, the Gulf of Mexico
d. Texas has a mild climate throughout the year
17. In August of 1999, Hurricane Bret formed in the Bay of Campeche and moved slowly northward
across the western Gulf of Mexico. The hurricane strengthened to a 140-mph hurricane, while
approaching the south Texas coast some 70 miles east of Brownsville. The hurricane made
landfall on Padre Island with 115 mph winds. Bret’s strong winds were confined to a small area
and only affected a sparsely populated region. The hurricane caused about $60 million in
damage, but no deaths. It was the first hurricane to affect south Texas since Hurricane Allen in
1980.
What was the most likely reason Hurricane Bret did not cause any deaths?
a. The winds were not that powerful
b. The hurricane was spread out over a large area
c. Few people live in the area where the hurricane struck
d. People were very cautious after experiencing Hurricane Allen
18. What went into the atmosphere in 1815 that caused worldwide temperatures to fall the
following summer?
a. Moisture from a vast flood
b. Debris from a meteor shower
c. Volcanic dust and ash
d. Increased carbon dioxide from burning fossil fuels
19. Chemical weathering is a type of weathering that physically breaks rock into smaller pieces
a. True
b. False
20. When wind carrying sediments slows down it deposits (drops) sediments to the ground. This is
called:
a. Mechanical Weathering
b. Chemical weathering
c. Erosion
d. Deposition
