CARD SORT – (sort into effect, description and reason)
The shape of the land
changes as parts get
smoother and other
steeper.
RELIEF
RIVERS
Craters form where
eruptions begin. Over
time these basins fill
with rainwater to
form lakes.
Lava flows can fill
valleys making the
relief smoother or
erode loose material
making them steeper.
SOILS POSITIVE
CLIMATE
Some landforms are
blown apart by the
eruption or the top of
mountains is
reduced.
Over a long time soils
become more fertile
VEGETATION
The particles in the
air block out the sun
and react with water
vapour to produce
mild acids.
Extreme explosive
eruptions will change
rock into ash and
form huge craters or
calderas.
Trees are flattened by
huge pyroclastic
flows or burnt by
advancing lava.
LANDFORMS
DESTROYED
Minerals are
deposited in the soils
such as Iron that
makes them more
fertile over time.
In the short term
soils are infertile
The ash covers the
soil and strips them
of essential minerals
so nothing can grow.
LANDFORMS
CREATED
Volcanic eruptions
can cause red skies
and heavy acidic
rainfall.
The course of a river
is likely to change
during an eruption
Forests will be
destroyed
SOILS NEGATIVE
Rivers are blocked by
lava flows or debris
dumped by lahars.
New lakes are formed
in old crater sites

(WHY)
1. Sort out the cards into the categories above
2. For each line provide an example using a case study
3. Then use this as a basis to answer the question.
Fully explain how your extreme natural event has effected the
natural environment in different ways using case study
evidence.
