Different Types of Volcanoes
We are learning about different types of volcanoes.
Composite Cone
The volcano is built up of alternate layers of LAVA and ASH. They can explode with great violence.
Mt St Helens - USA
Conelet
Dyke
Crater
Ash layer
Lava Layer Flank eruption

Pyroclastic Flow
Mount Saint Helens, USA
Shield ( Basic) Cone
Shield Volcanoes are enormous featuresbuilt up only from layers of lava. They produce lots of lava but they tent not to erupt violently.
Mauna Loa Hawaii -USA

Layers of Lava Lava Flow
Soufriere Hills, West Indies
Ash and Cinder ConeParacutin - Mexico
Layers of Ash and Cinder
Volcanic Bombs
Pipe
The volcano is built up of layers of ASH. When it erupts it is normally with great explosive force.

We are learning about different types of rocks
Do you think this feature is natural or man-made?
Is it hard or soft rock?What types of rock can you
name?
• Granite• Slate• Marble• Chalk• Limestone• Sandstone• Basalt
Igneous Metamorphic Sedimentary
Made from basalt andShale that has been
pressurised
Made from sand that has been
squashed together
sandstone
marble
schists
basalt
limestone
granite
Made from the shells And skeletons of sea creatures
Squashed together
Made from limestone that has been
subjected to heat and pressure
Made from magma whichHas cooled inside the
Earths crust.

We are learning about the location of different rock
types in the UK
Chalk and Clay
Limestone
The Tees-Exe line
Tees - Exe line
The Tees-Exe line
• The general pattern is the rock to the SE of the line is soft e.g. chalk and clay. Rock to the NW of the line is harder e.g. Granite.
Describe the distribution of rock types in the British
Isles• Talk about the pattern of where
the different rock types are. Use your planner map or an atlas, locating and naming places.
We are learning about different types of weathering and how they affect different
rocks
Do you think this feature is natural or man-made?
Is it hard or soft rock?This rock feature was created
by weathering try to explain how.
We are learning about different the characteristics
and features of granite landscapes
Where is Dartmoor?
How are Tors formed?
