The Earths crust is unstable,

especially at plate margins.

Distribution of plates, contrasts between

continental and oceanic plates.

Destructive, constructive andconservative plate margins.

G

ni!ue landforms occur atplate margins.

"ocation and formation of foldmountains, ocean trenches, compositevolcanoes, and shield volcanoes.

#

$eople use these landforms asa resource and adapt to the

conditions within them.

% case study of one range of foldmountains. The ways they are used &

farming, 'E$, mining, tourism and howpeople adapt to limited communications,steep relief and poor soils.

*olcanoes are ha+ards resultingfrom tectonic activity. Theirprimary and secondary eectsare positive as well asnegative. #esponses change inthe aftermath of an eruption.

Characteristics of dierent types ofvolcanoes. % case study of a volcaniceruption & its cause- primary andsecondary eects- positive and negativeimpacts- immediate and long termresponses. onitoring and predictingeruptions.

Supervolcanoes are on a muchbigger scale than othervolcanoes and an eruptionwould have globalconse!uences.
