What is the main factor causing the salinity of the Everglades to change?
climate change
flood control levees
transportation canals
snake populations
This is for connections academy please i need help
I have the answers!!
1. Climate change
2. python
3. Both species’ populations were affected by human actions that caused environmental changes.
4. Captive-bred whooping cranes have been introduced to natural environments.
5. Burmese python numbers increased, and mammal populations decreased.
100%
Climate Change
we could not find the information in the lesson either. I did a google search and just took the test and this is the correct answer.
Midnight is correct
The main factor causing the salinity of the Everglades to change is the construction of flood control levees and transportation canals. These human-made structures were designed to control and divert water flow in the region, but they have significantly altered the natural water balance of the Everglades.
To understand this better, let's break it down step by step:
1. Climate Change: While climate change does have an impact on the entire planet, it is not the primary factor causing changes in the salinity of the Everglades. However, it can indirectly affect the Everglades by altering rainfall patterns and increasing the frequency of extreme weather events like hurricanes, which can influence water levels and salinity in the region.
2. Flood Control Levees: The construction of flood control levees is one major factor contributing to the changes in salinity. Levees were built to protect human settlements from flooding by containing water within certain areas. However, these structures disrupt the natural flow of freshwater across the Everglades. As a result, water that used to flow through the Everglades more evenly is now often diverted away or held back, leading to reduced freshwater input and increased salinity in parts of the ecosystem.
3. Transportation Canals: Similarly, transportation canals have been constructed to facilitate water management and provide water supply for urban areas. These canals also alter the flow of freshwater within the Everglades, leading to changes in salinity levels. The canals often redirect freshwater away from the Everglades, leaving some areas with less freshwater input and higher salinity levels.
4. Snake Populations: While snake populations, especially invasive species like the Burmese python, can have ecological impacts in the Everglades, they are not the main factor causing changes in salinity levels. Snake populations might affect the natural balance in the ecosystem by preying on native species, but their influence on salinity is not significant compared to the human-made alterations mentioned earlier.
So, in summary, the primary factors causing changes in the salinity of the Everglades are the construction of flood control levees and transportation canals, which disrupt the natural water flow and decrease freshwater input.
