Geography Key words
- OCEANIC TRENCH
- A long narrow but very deep
depression in the ocean floor,
where at the junction of 2 plates,
1 plate dives steeply beneath
another & penetrates the mantle
- Penetrate: forcing
into something
- Penetrate: forcing

- SUBDUCTION ZONE
- A subduction zone is a
region of the Earth's crust
where tectonic plates meet.
(E.g: Where a continental
plate meets an oceanic
plate). Subduction zones
occur where plates collide

- OCEAN PLATE
- An ocean plate is a
tectonic plate mainly
underneath the ocean & a
continental plate is mainly
underneath a continent
- An ocean plate is a
tectonic plate mainly
underneath the ocean & a
continental plate is mainly
underneath a continent
- DIVERGENT
- When plates pull apart, earth
fractures & breaks causing
shallow earthquakes along the
plate boundary. When they are
getting separated, a new crust
is formed from magma that
rises to the Earth's surface
between the 2 plates. (New
land & islands are formed)
- E.g: the Mid-Atlantic ridge (the
major site of volcanic &
earthquake activity), or the
East-African Rift Valley (is
opening up & new land is being
formed in the bottom of the valley

- CONVERGENT
- A convergent plate boundary (sometimes called a
destructive plate boundary) occurs when oceanic &
continental plates move together. The oceanic plate
is forced under the lighter continental plate. Friction
causes melting of the oceanic plate & may trigger
earthquakes. Magma rises up through cracks &
erupts onto the surface. (Land gets destroyed)
- Are recognised by: A
very deep ocean trench,
large numbers of
earthquakes & also large
numbers of volcanoes
- Example:
subduction, of the
Nazca plate
beneath the South
American plate, to
form the Andes

- HUMAN
- Human geography
focuses on the study of
human interaction with the
environment, its cultural,
social & economical
aspects. Can also be
something man-made,
e.g: a building, etc.

physical structure,
atmosphere, soil, rock, water,
& related natural processes

service in relation to
the amount of money,
time or effort spent

with the relation of physical &

production of raw materials & their
manufacture into finished products

emphasis on social factors
