|
Interacting natural processes |
Processes that operate together to shape the environment -May include how processes operate at different rates and scales to create variation (spatial and/or temporal) |
|
|
Geographic environment |
Features and characteristics of a specific area |
|
|
What interacting process are we studying? |
The formation of an andesitic stratovolcano in the TVC (e.g. Mt Ruapehu) through interacting natural processes |
|
|
What are the 3 points that must be covered? |
1) How interacting processes operate to produce features in the TVC 3) Temporal variation in the operation of the interacting processes (e.g. how the operation of the processes change through time) |
|
|
Andesitic lava erupts out of |
the vent of the volcano to form layers in the stratovolcano (V) |
|
|
When was the last lava eruption of Mt. Ruapehu? |
2005 |
|
|
Fissure/crack in volcano for what purpose? |
For lava to travel to the surface (V) |
|
|
Magma pocket is formed where in andesitic volcanoes? |
Partway down the plate boundary (V) |
|
|
Magma chamber forms how? |
Forms through the 2 plates rubbing together with one sub-ducting (Pacific Plate) below the other to cause friction (P.T) |
|
|
What do convection currents do? |
They move in the mantle and drag tectonic plates around (P.T) |
|
|
What is a caldera? |
A very large depression caused by the collapse of the magma chamber of a rhyolitic volcano |
|
|
Caldera example |
Lake Taupo |
|
|
What is an andesitic stratovolcano? |
Andesitic = type of lava between basic and acidic rhyolite and basalt, strato = [many] layers |
