Task 1流程圖

(A)段

There are four sources of nitrogen in the ground water.

1. Most nitrogen in the ground water comes from industrial leaks from storage tanks and wastewater ponds.

2. Next,watse disposal in landfill, the second highest source, also contributes a a lot of nitrogen to the ground.

3. The third important/significant is fertiliser and household liquid waste from domestic and market gardens.(直接把圖片資訊挑明出來)

4. Coastal vegetation produces little nitrogen through nitrogen oxidisation by lightning and nitrogen fixation by vegetation.

(B)段

After nitrogen enter the water table, the nitrogen can be recycled in 4 ways.

The majority of nitrogen in the groundwater moves/goes/runs along the saltwater interface and is discharged at / arrives at / reaches  the groundwater discharge zone, where the land meets the ocean. The other 3 ways to recycle the

nitrogen in the groundwater are denitrification, ammonia degassing and nitrate uptake by soil particles.

3. Electricity Generation (Revised Version)

Given is the diagram illustrating the process of generating hydro-electric power involving the natural resource as well as certain human-built equipment.

First of all, the sun evaporates the seawater, transforming it into clouds. Then, when it rains, the water arrives at the ground in the form of rain and will be stored in the reservoir for the purpose of electricity generation. Also, a dam is built to prevent the water from leaking out.

 Afterwards, the water can go through the valve when it is opened. This movement forces a turbine to rotate and sends the water to the pump and finally the water returns to the reservoir. Then, a new cycle will begin. 

Through this water recycle process, electricity is produced and then transmitted to the transformer station by high voltage cables. The transformer station is responsible to provide the urban facilities, including schools and hospitals, with power through underground cables.

Overall, ....(結論請自己寫)
