Step 1
Step 2
Give an advantage and a disadvantage, to local communities, of a nearby limestone quarry.
Answer
Advantage: Quarrying limestone creates local jobs and can boost the local economy through the sale of materials.
Disadvantage: Quarrying can lead to environmental degradation, including loss of biodiversity and disruption of local habitats.
Step 3
Step 4
Describe how the limestone was originally formed and has become the cliff face shown in the photograph.
Answer
Limestone was originally formed from the accumulation of sediments, including shells and marine organisms, at the bottom of ancient seas. Over millions of years, these sediments compacted and cemented together, forming limestone. Geological actions, such as tectonic uplift, have then forced these limestone layers upwards, creating the cliff face observed in the photograph. Erosion over time further shaped the cliff, revealing the limestone structure.
