Module 5 Flashcards
What is Gondwana?
An ancient supercontinent that included what now are the continents of South America, Africa, Antarctica, Australia, the Indian subcontinent, and Zealandia.
What tectonic plates does New Zealand straddle?
New Zealand straddles the boundary between two tectonic plates: the Pacific Plate and the Indo-Australian Plate. The North Island of New Zealand sits on the Australian Plate, while the South Island lies on the Pacific Plate. This tectonic boundary is known as the Alpine Fault, which runs along the western side of the South Island.
How are mountains formed?
The collision and convergence of tectonic plates resulted in the uplifting of rocks and the formation of mountain ranges. Glacial erosion during the Pleistocene epoch further sculpted these mountains, creating rugged peaks and valleys.
How long ago did what is now New Zealand start to separate from Australia?
85 million years ago
What factors affected the New Zealand landscape in the last 5 million years?
By a combination of tectonic activity, glacial and interglacial periods, volcanic eruptions, and erosion. Tectonic forces continued to shape the landforms, while glacial periods sculpted the mountains and valleys through erosion.
When did humans arrive in Aotearoa, and how do we know?
1250-1300 AD.
We know this through archaeological evidence, such as tools, weapons, and other cultural characteristics of Polynesian culture
How long after human arrival were moa hunted to extinction?
200 years
- What were the main species that went extinct during the Māori period?
- moa
- haast’s eagle
- giant weta
What are the major environmental impacts that occurred after Māori arrival?
Deforestation - clearing large areas for cultivation
Hunting and fishing - exploited resources leading to decline or extinction in species
Introduction of invasive species - Polynesian rat (kiore) and the domestic dog
What does Kaitiakitanga mean?
Guardianship - it is the obligation, arising from the kin relationship, to nurture or care for a person or thing.
What does Taonga mean?
Treasure - where kaitiaki obligations exist, they do so in relation to taonga, - that is, to anything that is treasured.
What is the key difference between Mātauranga Māori and the European knowledge system?
European philosophy placed humanity at the top of a hierarchy, above ‘nature’. Māori philosophy places humanity within ‘nature’, with recognition of connections and responsibilities.
What were the effects of Māori interaction with the environment?
-habitat modification (burning forests)
-extinction of vulnerable species
-integration of new species
- human mediated changes in species distributions
What is Rāhui?
the temporary ban or closed season placed on an area or resource, has been used by Māori to manage resources for generations. This allowed those populations of species to relocate from that change in the environment.
Which species introduced to Aotearoa by humans, but excluding humans themselves, is directly responsible for the greatest number of extinctions of species endemic to Aotearoa?
Kiore, Pacific rat/Polynesian rat (Rattus exulans)
