Cinder cone
Cinder cone is a cone shaped volcano
A cinder cone or scoria cone is a steep conical hill of loose pyroclastic fragments
Cinder cones are the simplest type of volcano
They are built from particles and blobs of congealed lava ejected from a single vent.
Cinder cones tend to be small, like hill-sized volcanoes When lava that is in cinder cone is highly charged with gas bubbles erupts from a vent under pressure, it tends to shoot straight up into the air.
Cache Hill is a cinder cone in northern British Columbia, Canada. It is thought to have last erupted in the Holocene period.
Mount Eden is a scoria cone in Auckland in New Zealand.
Mount Leura is a 313 metre scoria cone surrounding a dry crater
Cinder cone volcanoes are just one of many types of volcanoes. A cinder cone, or scoria cone, is a steep conical hill made in large part of pyroclastic fragments. They are the simplest type of volcano and tend to be small and hill like. They are built …show more content…
They are formed by lava flows of low-viscosity, so over time and flow after flow, it is what makes the mountain grow.
Shield volcanoes are broad, domed shaped volcanoes with long, gently sloped sides.
Shield volcanoes form like any volcanoes. They’re spots on the Earth where magma from inside the Earth has reached the surface, and becomes lava, ash and volcanic gasses. Over the course of many eruptions, a volcano builds up layer by layer until the magma chamber underneath it goes empty. Eruptions at shield volcanoes are only explosive if water somehow gets into the vent.
Rangitoto island is a shield volcanoes in Auckland in New Zealand. It erupted around 550 years ago.
Kohala is the oldest of five volcanoes that make up the island of Hawaii.[3] Kohala is an estimated one million years old—so old that it experienced, and recorded, a reversal of magnetic field 780,000 years ago. And it have last erupted 120,000 years
