Will Zealandia become a continent?
Scientists confirmed the existence of an eighth continent, called Zealandia, under New Zealand and the surrounding ocean in 2017. Because 94\% of Zealandia’s 2 million square miles are underwater, mapping the continent is challenging.
Can we make a new continent?
It is possible, in some places, to build some real continents. If the ocean is shallow enough, we can excavate matter from the bottom and move it to create high mountains, reaching above surface. This technology might prove expensive, but at least we can create some real islands and in some cases real continents.
Could the eighth continent be there in the world?
An eighth continent, called Zealandia, is hidden under New Zealand and the surrounding Pacific. Since 94\% of Zealandia is submerged, discerning the continent’s age and mapping it is difficult. New research suggests Zealandia is 1 billion years old, about twice as old as geologists thought.
How old is Zealandia?
Zealandia broke off from Antarctica about 100 million years ago, and then from Australia about 80 million years ago. Zealandia is about half the size of Australia, but only 7 percent of it is above sea level.
What animals live in Zealandia?
Birds
- Black shag (kawau pū) (Phalacrocorax carbo novaehollandiae)
- Fantail, North Island (piwakawaka) (Rhipidura fulginosa placabilis)
- Falcon, New Zealand (kārearea) (Falco novaeseelandiae)
- Grey warbler, New Zealand (riroriro) (Gerygone igata)
- Little black shag (kawau tūī) (Phalacrocorax sulcirostris)
How fast is NZ sinking?
“The data also show inland areas of the South Island and the Southern Alps are rising by up to 6mm per year, while in the Rotorua area there is a remarkable subsidence rate of 15 mm per year.
Is Zealandia a new continent?
A team of geologists pitched the scientific case for judging this a new continent in the March/April issue of GSA Today. Zealandia is a continuous expanse of continental crust. It covers some 4.9 million square kilometers (1.9 million square miles). That’s about the size of the Indian subcontinent.
What is the history of Zealandia?
Zealandia probably began as part of the southeastern edge of the supercontinent Gondwana before it began peeling off around 100 million years ago. This breakup stretched, thinned and distorted Zealandia, which ultimately lowered the region below sea level. Journal: N. Mortimer et al. Zealandia: Earth’s hidden continent.
What is the name of the new continent under the ocean?
Zealandia The name for a proposed new continent that sits largely submerged beneath the ocean. If confirmed, it would be the smallest continent. The only easily visible parts of it are New Zealand and New Caledonia. These islands rise east of Australia in the Southern Hemisphere.
Why study the geology of Zealandia?
It also could aid in the study of how geologic forces reshape landmasses over time. Zealandia probably began as part of the southeastern edge of the supercontinent Gondwana before it began peeling off around 100 million years ago. This breakup stretched, thinned and distorted Zealandia, which ultimately lowered the region below sea level.
