This EarthCache will take you to a sea cave, to log the find you will need to explore inside and see what the sea has to say.
Sea caves are formed from the forces of the sea, waves seething at the rock face of a coastline sometimes produce huge caverns, which are typically not very long. They are as long as the water reaches. The existence of this caves is not dependent on the kind of rock. Of course, it helps if the rock is weaker.
Typically sea caves are formed using a weakness in the rocks, like faults, other sediments or weaker layers. Faults in the rock sometimes produce chains of caves; everywhere the fault reaches the seashore.
Sometimes faults, existing caves, or weaknesses in the rock produce a small hole to the surface. The water swashing into the sea caves build up a high pressure inside the cave, which emerges in form of water and air from the small hole. This is called a blowhole. They are found all over the world along the coasts.
Sea caves are formed by the power of the ocean attacking zones of weakness in coastal sea cliffs. The weak zone is usually a fault, or fractured zone formed during slippage. Another type of weak zone is formed where dissimilar types of rocks are inter-bedded and one is weaker than the other. Typically this is a dike, or intrusive vein of more easily eroded rock found within a stronger host rock. The cave may begin as a very narrow crack into which waves can penetrate and exert tremendous force, cracking the rock from within. Sand and rock carried by waves produce additional erosive power on the cave's walls
Caves may be found in a wide variety of host rocks, ranging from sedimentary, metamorphic or igneous, but caves in the latter tend to be larger due to the greater strength of the host rock.
Most sea-cave walls are irregular and chunky, reflecting an erosional process where the rock is fractured piece by piece. However, some caves have portions where the walls are rounded and smoothed, typically floored with cobbles, as result from the swirling motion of the surf zone.
It's posible to exit the cave two other ways than you went in. not a requirment but if you're more adventours the option is there.
logging requirments.
1. Along the left wall you will notice something, what is it and why do you think this happend?
2. As you move into the cave you will see / feel the cobbled floor in the surf zone as you move from swimming to walking, describe the cobles?
3. from the outside, can you identify a blowhole? where is it?
4. from the sea cave illustration can you identify any other fetures?
To get to the cave i've seen pepole swim, kayak and hire peddle boats from Ayia Napa. The yellow submarine boat tour also stops here if you are not so athletic.
DO NOT ATTEMPT THE CACHE IN BAD WEATHER OR IF YOU ARE NOT 100% SURE OF THE CONDITIONS.
