Answer:
A)
Explanation:
I found the rest of your question.
A. increased water scarcity B. overfishing C. decreased soil salinity D. deforestation
Overfishing, decreased soil salinity and deforestation are concerns about agricultural production and its effect but the increased water scarcity is not.
Overfishing is considering a fish species from the water and because of that population of fish is lack which is not good.
Soil salinity can stop the plant from growing and also the quality of water.
Deforestation is the removal of forests or trees and it has a big effect on agricultural production.
Answer:
to provide a reference system
Explanation:
The equator and prim meridian used on maps provides a reference system for determining location and navigating the earth.
- An equator is the only line of latitude that is a great circle.
- Prime meridian is a line of longitude that is 0°
- When both are used, they can form the basis of a reference system to determine places on earth.
- Using these lines, we can assign values of coordinates to the earth surface to facilitate location determination.
The equator and prime meridian are used on maps to provide a reference system.
a) <u>TWO important causes for the variation in the temperature and/or salinity of an estuary as follows:</u>
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) <u>TWO roles that coastal wetlands play Ecologically</u>
- they provide a habitat for various wildlife
- provide nutrient cycling, or soak up excess nutrients.
<u>TWO roles that wetlands play Economically</u>
- they provide a location for fishing and other sources of recreation
- reduce flooding and erosion.
c) <u>THREE ways in which humans have had a negative impact on or have degraded coastal wetlands as follows:</u>
- They have removed wetlands for agricultural purposes
- more use of groundwater, which reduces the balance of the ecosystem
- have 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.
<u>Explanation:</u>
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.
