Match the area with its description.
A. Southern Highlands
B. Southern Lowlands
C. Northern Lowlands ✔Correct Answer-A. Higher rainfall than the other regions, volcanic and
metamorphic rock, deepest water table
B. Consistent rainfall with some seasonal variability, abundant limestone, deep water table
C. Rainfall was strongly seasonal, abundant limestone, shallow water table
Cenotes were abundant in the rainy Southern Highlands where limestone is abundant.
✔Correct Answer-False, they were abundant in the Northern and Southern lowlands
What technology was developed and natural features were used to access and store water?
✔Correct Answer-A. Drilled wells (up to 90 ft deep)
B. Aguadas
C. Chultuns
D. Cenotes
E. Lakes and freshwater lagoons
F. Water seals such as impermeable clay, stone, or plaster to help retain water.
G. Cities with infrastructure built to channel, collect, and sometimes get rid of water.
What are the advantages of raised bed agriculture? ✔Correct Answer-A. The beds are self-
watering
B. The aquatic animals living in the canals can also be collected for food
D. The fertile soil from the canals can be put on the beds to replenish nutrients
Only used in lowlands.
What are the advantages of terraced agriculture? ✔Correct Answer-A. They work in mountain
areas with rocky soil and steep slopes
D. The terracing helps retain soil
They did not act as a reservoir during dry season, and topsoil/nutrients were not permanently
retained.
What are the advantages of the milpa-forest garden agriculture? ✔Correct Answer-A. About
two-thirds of the farmland is actually maintained as forest
B. The cycle of slash and burn, growing mixed crops, and then allowing the forest to regrow
helps recycle and retain soil nutrients
C. This type of farming supports biodiversity including wild animal life
, D. There are few issues with erosion since the soil is not plowed
E. It provides additional valuable goods and services such as building supplies and medicines
The milpa-forest garden technique is highly productive and sustainable; therefore, it seems
unlikely that environmental degradation was a driver of Maya collapse. ✔Correct Answer-True
Which statement is false?
A. The ancient Maya civilization left extensive deciphered written texts
B. The Maya made stone tools out of obsidian
C. Ancient Maya culture was lost entirely with its collapse
D. Trade with neighboring societies was not a factor in the Maya collapse
E. The Maya homeland is a seasonal tropical rainforest with risk of droughts and hurricanes
✔Correct Answer-C. Ancient Maya culture was lost entirely with its collapse
What were the limitations of Maya agriculture according to Diamond? ✔Correct Answer-A.
Corn agriculture was less productive
B. The humid climate made it difficult to store corn
C. In some areas, there were water shortages resulting from the local geological features (low
water table and limestone) and occasional droughts
D. The dominant crop, corn, yielded little protein
F. The Maya had no animal-powered transport or plows
What were the consequences of the agricultural limitations according to Diamond? ✔Correct
Answer-A. There was limited duration and distance possible for their military campaigns.
B. Maya society remained politically divided among small kingdoms that would go in and out of
conflict with each other.
C. Maya cities remained small, mostly less than one square mile in area and with populations
less than 50,000 people.
D. A Maya farmer could produce only twice the needs of himself and his family, so at least 70%
of Maya society consisted of peasant farmers to supply enough food for their entire society.
Deforestation can lead to hillside erosion, reduced soil fertility, and a man-made drought.
✔Correct Answer-True
Lake sediment cores were used to identify drought conditions from gypsum and oxygen isotope
measurements as well as deforestation from pollen records. ✔Correct Answer-True
What nuances complicate the story of Maya collapse? ✔Correct Answer-A. There were
smaller collapses before and after the larger "Classic" collapse that occurred in ~ A.D. 800.
B. Many cities experienced "power cycling" where the leadership changed hands but the
population itself remained the same.
C. There were hundreds of thousands of Maya who survived the collapse and lived to fight the
Spaniards.
D. Cities in different areas where the Maya lived rose and fell at different times.
