Processes active in TVC

land building processes responsible for many of the landforms at the TVC

volcanism, folding and faulting

processes that are responsible for wearing down the land

erosion, transportation and deposition

glacial (ice)

aeolian (wind)

fluvial (rivers)

caused by 2 plates pushing against each other and the softer rock is pushed and squeezed by the harder rock causing it to bend and twist to form series of hills and valleys

Kaimanawa Ranges

the movement of parts of the earths surface along areas of weakness known as fault lines, this results in earthquakes which move land in large solid blocks of rock

Rotorua-Taupo volcanic zone

rock is broken down into finer fragments that can be moved elsewhere by energy agents such as wind, water or ice

temperature, water, wind and plants

when the energy of an agent is high meaning that sediment can be picked up and carried along with the wind/water/ice

when the energy of an agent is low meaning that any sediment carried is dropped or deposited

fluvial processes

aeolian processes

glacial processes

ice hollows out rock using freeze-thaw action and as a result a U shaped valley is left behind

Whangaehu, Whakapapa and Mangatepopo

running water erodes into land surfaces and transports the products of erosion and deposits them

abrasion, hydraulic action and attrition

solution, suspension, saltation, and traction

river speed isn’t enough to carry sediment and it is deposited, this mainly occurs in the lower parts of the river
