- 10. The characteristic blue waters of Cape Greco are a result of the seabed composition and the clarity of the water. While not directly involved in cave formation, the surrounding environment is crucial. What contributes to the clarity of the water at Cape Greco?
A) Frequent storms
B) Presence of seagrass beds and sandy bottoms
C) Pollution from boats
D) High sediment runoff

A) Feed the local marine life
B) Leave behind any collected rocks
C) Avoid touching or disturbing the rock formations
D) Swim directly into large caves without caution
- 13. The term 'sea arch' is often associated with the evolution of sea caves. Sea arches form when erosion continues to widen a cave's entrance or when two caves meet. What is a sea arch?
A) A deep underwater trench
B) A rock formation spanning across the water
C) A circular pool of water
D) A natural bridge on land
- 14. The unique light conditions within sea caves can create striking visual effects, especially when sunlight penetrates the water. What phenomenon can be observed in some sea caves due to light refraction?
A) Rainbow formation
B) Mirages
C) Aurora borealis
D) Bioluminescence
- 15. The process of erosion that forms sea caves is a slow but powerful force of nature. Understanding this process helps in appreciating the geological timescale. How long does it typically take for a significant sea cave to form?
A) A few days
B) A few decades
C) A few months
D) Thousands of years
- 16. The geological history of Cape Greco indicates periods of geological activity that have shaped its landscape. While sea caves are a result of ongoing erosion, the underlying geology is a product of past events. What broad geological process formed the landmass of Cyprus?
A) Volcanic eruptions
B) Meteorite impacts
C) Continental drift over millions of years
D) Tectonic plate movement
- 17. The presence of fossils within the limestone at Cape Greco can provide clues about past environments. These fossils are remnants of ancient life. What type of marine organisms are commonly found as fossils in the limestone of this region?
A) Mammoths
B) Dinosaurs
C) Amphibians
D) Shellfish and corals
- 18. The accessibility of some sea caves at Cape Greco allows for exploration. However, it's crucial to be aware of potential hazards. What is a primary safety concern when exploring sea caves?
A) Changing tides and wave surges
B) Sudden temperature drops
C) Abundant land predators
D) High altitude sickness
- 19. The ecological importance of sea caves extends to their role as shelter for marine life. This includes providing refuge from predators and harsh weather conditions. What are sea caves often referred to as for certain marine species?
