All environmental conditions in the coastal regions tend to vary on the basis of hours and season.

The are several conditions like salinity which vary hourly, due to tides. Secondly, the temperature varies based on the period of year. The solar radiation also deferrers in winters. Ecologically they give habitat to various wildlife also provide nutrient cycling, provide a location for fishing, and secondly, reduce flooding and erosion activity. The 3 ways like the removal of wetlands for agricultural purposes. Overuse of groundwater, Water pollution, and hunting the birds. Overuse of groundwater can decline by user fees to those who use it, increasing the wildlife refuges, that will restrict available land for the groundwater.

Answer from: crystaldewar55C

a) TWO important causes for the variation in the temperature and/or salinity of an estuary as follows:

Salinity will vary hourly, because of the tides. Temperature will vary depending on the time of year. Solar radiation, different in winter than in summer, changes the temperature.

b) TWO roles that coastal wetlands play Ecologically

they provide a habitat for various wildlifeprovide nutrient cycling, or soak up excess nutrients.

TWO roles that wetlands play Economically

they provide a location for fishing and other sources of recreationreduce flooding and erosion.

c) THREE ways in which humans have had a negative impact on or have degraded coastal wetlands as follows:

They have removed wetlands for agricultural purposesmore use of groundwater, which reduces the balance of the ecosystemhave water pollution, plants harvest, and birds hunt.

d) Overused groundwater can be reduced by charging user fees to those who use it, as well as increasing the number of wildlife refugees, which will restrict available land for groundwater use.

Explanation:

Estuary is a land form that formed in the lower course of a river where river enters into the sea. Here temperature and salinity varies with solar radiation as the intensity of sun rays different season wise. During the time of tides salinity level does fluctuate.

Wetland is a very important feature of environment. It is also known as the kidney of environment and it acts as a natural habitat for the animals and economically important zone for the fishing. It is also a recreation zone. With increasing population over burden on agricultural land enhances adversities on environment.
