Explanation:

1. Mexico City was built on an ancient lake bed.  The Spanish built Mexico City on an island in Lake Texcoco that was drained. Nowadays, a part of the city stands on layers of sand and clay that used to be under the lake. This means the city is vulnerable to earthquakes.

2. Cerro Negro is a volcano placed in León, Nicaragua. Its name comes from its color.

3. Hummingbirds are the smallest birds on the planet and although there are 341 different types of hummingbirds more than 50 of them can be found in Costa Rica.

4. The sale of Panamá hats funded a revolution in Ecuador because Panamá hats are from Ecuador, not Panamá. However, they were often sent to Panama before being shipped to the rest of the world and that generated confusion.
