A tropical storm hits Florida, bringing heavy rain for days. The local rivers are overflowing. After the storm, what would we MOST expect to find in regard to the salinity of local lagoons?
(1 point)
Responses
decreased salinity because a large amount of salt water would flow in
decreased salinity because a large amount of salt water would flow in
decreased salinity because a large amount of fresh water would flow in
decreased salinity because a large amount of fresh water would flow in
increased salinity because a large amount of salt water would flow in
increased salinity because a large amount of salt water would flow in
increased salinity because a large amount of fresh water would flow in

increased salinity because a large amount of salt water would flow in
increased salinity because a large amount of salt water would flow in
increased salinity because a large amount of fresh water would flow in
After the storm, we would MOST expect to find decreased salinity because a large amount of fresh water would flow in. The heavy rain would increase the amount of fresh water entering the lagoons, diluting the salinity.
Tim is snorkeling in kelp forests in South Africa and collecting water samples. Assuming the water there is healthy, what can Tim MOST likely predict about it?

The water will be warm and high in dissolved oxygen.
The water will be warm and high in dissolved oxygen.
The water will be cold and high in dissolved oxygen.
The water will be cold and high in dissolved oxygen.
The water will be warm and high in dissolved carbon dioxide.
The water will be warm and high in dissolved carbon dioxide.

The water will be warm and high in dissolved carbon dioxide.
The water will be cold and high in dissolved carbon dioxide.
Tim can MOST likely predict that the water will be cold and high in dissolved oxygen. Kelp forests typically thrive in colder, nutrient-rich waters, and these environments often have high levels of dissolved oxygen due to the photosynthetic activity of the kelp.
