Mysterious Sea Caves Some of the most miraculous and mysterious caves known are sea caves. These caves are formed using the power of waves pounding against the shoreline. Sea caves are full of suspense. Come and lets travel through the flooded, underground, and fairytale caves made by waves. Sea caves can start as the smallest crack or weak spot on a cliff side. The wind and waves (which can carry sand) beat on the crack or weak spot until it falls off the cliff side. A sea cave can also be created by waves washing up the shore producing caverns, which are typically as deep as the waves can go. While it doesn't matter what kind of rock is along the shoreline, it helps the formation of the cave if the rock is softer. Caves that already exist and are widened by water erosion are called karst caves. You can find these caves near or opening on the shoreline. Don't you think that would be a great place for pirates to hide treasure? Actually, people do explore caves using boats, or walk in during low tide, but you better make sure that the tide is low and be sure you are wearing the right equipment. The power of a wave is stronger inside a cave. Water at the entrance can be very rough. Once inside the sea cave, you may see the mineral, Calcite, which is white. Calcite can be dry and look like white patches on sea cave walls. Remember a lot of what you find depends on the tide being high or low. If you look inside a sea cave, you would see a lot of life. Most of the life would be microorganisms, meaning they are to small to see. Most of these micro organisms are called extremophiles. They are able to live in places that others can't. There is a lot of other life in a sea cave. There are many gooseneck barnacles in a sea cave. There are also less common creatures in sea caves, like a small leopard shark. Most of the animals in a sea cave are blind. Even if they were not blind, it won't do them much good. Not much light gets into a sea cave. There is light only at the entrance, it is very dangerous. Some of the sea life help with weathering, like the sea star. The longest sea cave by volume is the Riko Riko Cave. According to its last scan about a year or two ago, it is over 7,800,000 cubic feet large! It only has a length of about 550 feet. The cave is mostly underwater with only about 35% of it above water, but its entrance is big enough to let a 50 foot boat inside! This is one very large cave. The longest sea cave on record is the Painted Cave in the United Kingdom. it is about 1,800 feet long! The entrance is big enough for a boat that is 40 feet tall. This cave is long, but it only has a volume 56% that of the Riko Riko Cave. It is about 65% above water. Now this is one long cave! When you think of a blowhole, you think of a whale. A geological blowhole is created when the sea cave goes toward land and water pressure builds up. When the weather is calm the blowhole can be a well, but when when the pressure builds up it sprout into a beautiful fountain of water. When the weather gets rough a blowhole turns into a out of control water fountain. A blowhole is usually located at the end of a sea cave. Waves enter the sea cave and all of the water goes toward the funnel and leads to the blowhole. Blowholes around the world are attractions that draw millions of people's attention every year. |
