Types Of Volcanoes 📖

Question 1

Four major types of volcanoes

Answer 1

Cinder cone, composite volcanoes, shield volcanoes, lava domes

Question 2

Lava and Lahar Flow

Answer 2

Molten rock and midflows flowing down the side of the volcano

Question 3

Composite Cone Volcano (Mount Pinatubo)

Answer 3

What shape : triangular cone shape
What was the lava like : viscous sticky lava
Frequency and magnitude of the eruptions : released poisonous gases like nitrogen oxide.

Question 4

Shield Volcano (Queen Mary’s Peak).

Answer 4

What shape : Sheila circular shape
What was the lava like : runny lava, spreads down the slope.
Frequency and magnitude: small eruptions erupted in 2004 category 6 volcano 10 million tons of magma.
What plate boundaries do the form on : South American and African plate

Question 5

Divergent

Answer 5

Types of crust : oceanic and oceanic
Plate movement : plates move apart
Major landforms : crates ocean ridge
Tectonic activity : Volcanoes and earthquakes not very violent, volcanoes also less destructive.

Question 5

Convergent

Answer 5

Types of crust : oceanic and continental
Plate movement : plates are collided and the crust is subducted under the other continental plate.
Major landforms : mountains e.g. Andes in South America
Tectonic activity: big earthquakes and volcanoes

Question 5

Collision

Answer 5

Types of crust : continental and continental
Plate movement : when two continental plates collide, forced upwards and downwards.
Major landforms : fold mountains e.g. Himalayas
Tectonic activity : large earthquakes because of friction

Question 5

Conservative

Answer 5

Types of crust : continental and continental
Plate movement : when two continental plates move alongside each other
Major landforms : no major landforms
Tectonic activity : huge build up so massive earthquakes occur
