Types of Mountains: Volcanic Mountains
- Volcanic Mountains - Volcanoes
that are Mountains:
These mountains are actually volcanoes.
- How Volcanic Mountains are Formed:
- Built Up by Ejected Material: They are formed from materials
that erupt from cracks (fissures) in the Earth's surface.
- What's Ejected? This material includes:
- Molten lava: Hot, liquid rock from inside
the Earth.
- Volcanic bombs: Big pieces of rock.
- Cinders, ashes, dust: Smaller bits of rock and ash.
- Liquid mud: Mud mixed with volcanic stuff.
- Layered Cone Shape: This material falls around the
volcano's opening (vent) and builds up in layers, making a cone shape.
(See Fig. 22 in your text).
- "Mountains of Accumulation": Volcanic mountains are also called "mountains of accumulation" because they are built up over time from volcanic materials.
- Where are they found?
- Circum-Pacific Belt: They are common around the Circum-Pacific
Belt, also known as the "Ring of Fire" around the Pacific
Ocean. This area has many volcanoes.
- Examples of Volcanic Mountains:
- Mt. Fuji (Japan)
- Mt. Mayon (Philippines)
- Mt. Merapi (Sumatra, Indonesia)
- Mt. Agung (Bali, Indonesia)
- Mt. Catopaxi (Ecuador)
In Simple
Words: Volcanic
mountains are simply volcanoes that have grown so big they become mountains.
They are made from layers of lava, ash, and rock that erupt from inside the
Earth and pile up around the opening of the volcano, forming a cone shape. Many
famous volcanoes around the Pacific Ocean are examples of volcanic mountains.
