Answer:
What happened in 1929 that helped end Florida's land boom was the Stock Market Crash.
Step-by-step explanation:
The Florida land boom was a real estate boom that took place in the 1920s in the US state of Florida.
In the early 1920s, Florida became popular as a living and recreational area. For this reason, substantial investments were made in land, hotels, homes and roads. Large land reclamation projects were set up over time. Parts of the Everglades (the wetlands in south Florida) were drained and artificial islands were built off the coast of Miami. When prices rose even further, even swamp areas that were not even at the sea or near a city were resold for big money. At the end of 1925 it went wrong and this real estate bubble burst.
In 1926, a hurricane devastated the area, leading to bankruptcy to urban projects such as Isola di Lolando. Another hurricane in 1928 and the Stock Market Crash of 1929 deepened the recessionary trend, which merged with the Great Depression that would soon take over the entire country. A year later a plague of flies Ceratitis capitata deepened the crisis of the tourist and agricultural sector.
