Types of volcanoes
What is a cinder cone volcano made of?
Is made up of small rock particles, or cinders.
How can we prepare for volcanic eruptions?
What is a vent where is it located?
They are located near the peak of the mountain. Is an opening exposed on the earth's surface where volcanic material is emitted.
How are volcanoes formed?
when hot molten rock, ash and gases escape from an opening in the Earth's surface.
True or flase: ash ejected by the volcano acts as a good fertiliser for soils.
TRUE!
What is a shield volcano?
This type of volcano is made up of layers of lava rocks. Low viscosity in lava
What to do during a volcano warning:
What are craters?
Craters are bowl-shaped depressions. Is an approximately circular depression in the ground caused by volcanic activity.
Explain the role of tectonic plates in the formation of volcanoes
As the denser plate edge moves downward, the pressure and temperature surrounding it increases
Name four major health threats from a volcanic eruption
Suffocation, water contamination, respiratory illness, burns
What is a composite volcano?
Is made up of layers of lava flows alternating with layers of ash, cinders, and rocks. It has multiple vents
Define Subduction Zone. Where is it located?
Sobduction occurs where two plates are converging on one another. Occur all around the edge of the Pacific Ocean.
Name three positive effects
Rising magma brings valuable minerals to the surface. It helps cool off the earth removing heat from its interior. Volcanoes make islands and add to the continents.
Which type of volcanic landform is the most destructive?
Composite volcano
Name 3 parts of a volcano
Vent, Eruption cloud, crater, acid rain, lava flow, subduction zone
Types of weather changes
Volcanoes can change the weather. They can cause rain, thunder and lightning.
