重點概念 Important Concepts

第五題 Question 5

正確答案 Correct Answer:C

重點概念 Important Concepts

  • 限制通道 Restricted Access
  • 電纜 Power line
  • 沼林 Mangrove

第六題 Question 6

正確答案 Correct Answer:C ( 62% )

重點概念 Important Concepts

第七題 Question 7

正確答案 Correct Answer:B

重點概念 Important Concepts

  • 錯動型 / 保守板塊邊界
    Transform / Conservative Plate Boundary
  • 圖中為聖安德列斯斷層,由剪切力所造成,沒有俯衝,亦沒有額外岩漿,因此並不會導致活躍的火山作用
    San Andreas Fault is shown above, which is formed by shearing force. Since there is no subduction, no extra magma is produced. Hence, active vulcanicity would not be resulted.

第八題 Question 8

正確答案 Correct Answer:A

重點概念 Important Concepts

  • 地殼為固態;而內地核和外地核則分別為固態和液態
    Crust is solid while Inner Core and Outer Core are solid and liquid respectively.
  • 地球的密度由外至內是越來越高
    The density of the earth is getting higher and higher from the outside to the inside.
  • 地殼的主要化學成分為矽、鋁和鎂,地核則為鐵和鎳
    Crust is mainly composed by Silica, Aluminum and Magnesium, while Core is mainly composed by Iron and Nickel.

第九題 Question 9

正確答案 Correct Answer:D ( 54% )

重點概念 Important Concepts

第十題 Question 10

正確答案 Correct Answer:A ( 47% )

重點概念 Important Concepts

  • 河盆坡度與河道徑流量成正相關
    坡度越斜,下滲越少,地表徑流越多,河道徑流量便越多。
    Slope gradient is positively related with the amount of channel flow
    With steeper slope gradient, there is less infiltration and more surface runoff, leading to an increase in the amount of channel flow.

  • 岩石透水性與河道徑流量成負相關
    透水性越高,下滲越多,地表徑流越少,河道徑流量便越少。
    Rock permeability is NEGATIVELY related with the amount of channel flow
    When rock is more permeable, more water can infiltrate, resulting in less surface runoff, and in turn channel flow.

  • 植被覆蓋密度與河道徑流量成負相關
    植被覆蓋密度越高,截留和下滲越多,地表徑流越少,河道徑流量便越少。
    Density of vegetation cover is NEGATIVELY related with the amount of channel flow
    When there is more vegetation cover, more water is intercepted and infiltrated, resulting in less surface runoff, and in turn channel flow.

提點 Reminder

  • 河盆 / 集水區大小與河道徑流量成正相關
    Size of drainage basin / catchment area is POSTIVELY related with the amount of channel flow
  • 若您未能正確回答本題,請重温「水循環」和「河流能量」的部分。
    If you fail answering this question, please review the “water cycle” and “the energy of a river” in your textbook.

第十四題 Question 14

正確答案 Correct Answer:C ( 74% )

重點概念 Important Concepts

  • X 計劃是行人專用區。
    Scheme X is pedestrian zone.

  • 行人專用區能改善行人的安全及流通情況。
    Pedestrian zone can improve pedestrian safety and mobility.

  • 該地區道路交通排放的空氣污染物能被有效減少。
    Air pollutants emitted by road traffic can be reduced in the area.

  • 徵收高額牌照費、燃油稅等措施可以減低私家車的使用,但行人專用區不能。
    Measures like imposing high license fees, fuel taxes can discourage the use of private cars, but pedestrian zones cannot.

第十五題 Question 15

正確答案 Correct Answer:A ( 65% )

重點概念 Important Concepts

第十六題 Question 16

正確答案 Correct Answer:D ( 28% )

重點概念 Important Concepts

  • 當硝酸鹽化肥被沖入河流或湖泊並積累時,這會增加水中的營養物質水平,即富養化。
    When nitrate fertilisers are washed into and accumulate in rivers or lakes, this will increase the level of nutrients in water, knowing as eutrophication.
  • 當化學肥料滲透到地下水中時,水就會被污染。
    When fertilisers percolate into ground water, water will be polluted.
  • 南加州炎熱乾燥的夏季會令受污染的地下水經由毛細作用上升到地表。
    The hot dry summer in Southern California leads to the rising of contaminated groundwater towards the land surface due to the capillary effect.
  • 當水蒸發時,鹽分會留在土地表面,導致土壤鹽化。
    When water evaporates, the salts are left on the surface of the land, causing salinization.

第十七題 Question 17

正確答案 Correct Answer : A ( 29% )

重點概念 Important Concepts

  • 人口高速增長和貧窮都會增加開採自然資源的需要,如肉牛放牧、商業種植園、商業伐木等,從而導致高濫伐林木率
    Both high population growth and poverty would result in the need for extraction of natural resources, including cattle ranching, commercial plantation, commercial logging, etc. All these eventually lead to high rate of deforestation
  • 香港考評局指城市化為巴西亞馬遜雨林裏高濫伐林木率的「主要原因」,而巴西境內的濫伐林木亦並非由急速的城市化所導致
