The Auckland Volcanic field

The Auckland volcanic field is made up of 50 basalt volcanoes.
The volcanic field is a hot spot because it in the middle of a tectonic plate, not around the edge.
Some volcanoes in the volcanic field only erupt once which means it is a mono-genetic volcano. There are some other volcanoes such as Rangitoto that erupt more than once these are polygenetic volcanoes.
The Auckland Volacnic field is a 1/4 (quarter) of a million years old.

When One Tree hill erupted its lava flow reached the edge of Mount Smart which made Mount Smart erupt. The lava flow finally found its escape route into the Manukau River Valley. The result was a 4 metre drop in the water level.

Some day in the future I hope there will be no volcanic eruption.
I will hate to see one.



Have you heard of these rocks before?

Igneous rocks are types of rocks that have crystals inside them.
When the molten magma rises to the earths surface it then cools down into Igneous rocks.
The Latin word for 'Igneous' is 'Ignis' which means fire. Pumice is an Igneous rock too.

Sedimentary rocks are made out of tiny grains of sand, clay, rock, plants, and animal skeletons. They fall down onto the ocean floor and over millions years, these are pressed together by the weight of water and layers of sediment on top to make Sedimentary rocks(the word 'sediment' means to 'settle in layers').
They also can have fossils inside them.
Limestone is a Sedimentary rock.

3) Metamorphic ROCKS-
Did you know deep in the earth's crust, rocks are crushed and 'cooked' into new rocks, that's why they are very hard. These rocks are called Metamophic('meta' means 'changed', and 'morph' means 'shape'). Marble is also a Metamorphic rock.

The Legend of Mt Taranaki

How Active is Our earth?

This term we are learning about Active Earth. We were asked to retell the story about the Legend of Mt Taranaki. My group chose to do green screening because we thought it would be a great way to retell the story.

My team members were Mui, Tracey, Mauina Including myself. We worked well as a team. We also had different responsibility. Mauina and Mui did the voice-over and I gathered all the photo's and we all worked on editing the project.

I really enjoyed working on this project and I also loved working with my team. Our group was also pleased with the result that we had. YES! we had the top marks which was 23/25.
