Why is the giants causeway hexagonal




















Incredibly, the stones are built not by a genius mathematician or engineer but by mother nature. The plinths here are in fact igneous basalt columns , created when molten lava comes up from inside the earth and cools.

As the rock cools it contracts, and this changing shape means that as it solidifies the rock must crack to release the pressure similar to the way that an ice cube warms, contracts and cracks when you put it into your drink. German physicists have devised a new model to help explain just how those neat geometric patterns emerge through natural processes. This sparked a lively debate about just how the causeway may have formed.

Scientists were inclined to search for less mythical explanations, reasoning that perhaps ordinary men had built the causeway, armed with pick and chisels. In , a French scientist named Demarest suggested volcanic activity might be the culprit, and this remains the accepted explanation. Those columnar joints were formed some 60 million years ago, as molten lava from a massive eruption flowed into the sea, cooling rapidly and shrinking into the hexagonal columns.

Heidi Henderson. The Giant's Causeway is a spectacular expanse of interlocking hexagonal basalt columns formed from volcanic eruptions during the Paleocene some million years ago. These columns tell a story of the cooling and freezing of the lava flows that formed them.

As lava at the surface cools and freezes, it also shrinks as its molecules rearrange themselves into a solid structure. This happens much more quickly at the surface where the lava comes in contact with moist, cool air. As the basalt cools and shrinks, pressure increases in intensity and cracks begin to form.

A way to dissipate this huge stress is to crack at an angle of degrees, the angle that gives us a hexagon. Found in Vietnam, Ghen Da Dia column rocks form a star design, unlike the other columns which form hexagons.

Located near the southeastern border of the Czech Republic with Germany, these beautiful columns provide visitors with picturesque views.

A range of mountains orchestrates this region with magnificent columns formed years back. This range of mountains consists of sandstone sedimentary rocks forming a crystalline basement. During this formation, lava broke through the sandstone and solidified to create basalt columns leading to the creation of this great feature in the Czech Republic.

These gorgeous cliffs can be visibly seen below the Reynisfjall Mountain. These columns can be found at the rear end of the mysterious black sand beach. Columns here rise to 66 meters above the waters. Reynisdrangar acts as a trademark for Vik in Myrdal, which is a village in Iceland. It is believed that two trolls had been pulling a ship to the beach, but they were not successful.

The elves were ambushed by sunlight in the morning, and they now turned into stone according to myths about trolls getting caught up by sunlight at dawn. A basalt rock formation that resembles a city wall and also looking like monoliths on land can be observed on the Taiwan Strait. The wall is 10 meters high and meters long in the water. Columns here resemble numerous pillars that have been put together. The basaltic features are a tremendous phenomenal since most of these features are seen above the water, but this is underwater.

Visit this great feature in Taiwan to enjoy the great sensation. Flores Island is found in the Western group of Azores. If there is a place you should visit, is this enchanting place. This Island in Portugal is characterized by an extremely rugged and heavily indented coastline. Flores is known to have magnificent waterfalls, streams, and striking columns. The Island is tiny, and you can discover it in a short period.

Explore the beautiful landscapes of this fascinating Island as you walk at the top of the basalt pillars. Litlanesfoss is the waterfall you will encounter as you move upstream to Hengifoss. It is notably the most exciting waterfall and geological phenomenon that one could ever find in Iceland. Spectacular columnar basalt outcrops the waterfall and stands at feet above the ground.

What happens at the lower tier. The waterfall and the columns do form the most magical phenomena in Iceland worth your time and money. Litlanesfoss is by far the most scenic waterfall orchestrated with the wondrous columnar jointing. Found 23 km just east of Armenia is an outstanding gorge with quite a dramatic topography. Along the sidelines of this gorge are fantastically arranged columns of basalt that were carved out by a river that cuts through the canyon known as Goght River.

The area is simply a ravine made of cliffs of hexagonal volcanic rock columns. The St. They are four tiny Islands found on the coast of Malpe, Karnataka, India. These islands are famous because of the columnar basaltic lava that was formed as a result of volcanic activities. Studies have shown that the basalt here was created as a result of sub-aerial subvolcanic.
