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

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.

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 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?
