An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.This is in contract to a dormant volcano, which is an active volcano that is not erupting, but supposed to erupt again. An active volcano is a volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant.
The Big Boom :P
You measure the amount of baking soda put in he volcano
Calderas form during massive explosve volcanic eruptions. In such eruptions so much material is expelled that it leaves a large empty space under the volcano. The volcano then collapses into this space, forming a giant crater.
Cinder Cone also known as Ash-cinder Volcano · Cone-shaped volcano · Steep side · Lava flows through a single vent · Usually a bowl-shaped crater at the top · Erupts into the air · Lava fragments forms cinders · Examples - Mount Tabor, Mount Zion Composite or Strato Volcano - most common volcano · Steep-coned volcano · Viscous slow moving lava · Emits gases, ash, pumice, silica lava · Eruptions can cause deadly mudflows · Examples: Mount St. Helens in Washington State, USA; Mount Pinatubo in the Phillippines Flood or Plateau Basalt also known as Fissure Volcano · Very liquid lava · Flows are widespread · Gentle basaltic slope of lava · Example: Columbia River Plateau Lava Dome · Rounded volcano · Lava barely flows · Example: Mount Pelee in Martinique Rhyolite Caldera Complex also known as Caldera Volcano · Most explosive volcanoes · Large volumes of magma erupts at once · Volcano collapses after explosive period · Example: Yellowstone, Wyoming, USA; Lake Taupo, New Zealand Shield Volcano · gently-sloping volcano · emits mostly basaltic (fluid) lava · gentle eruptions · explosions are minimal · can be very large · example: Mount Kilauea in Hawaii
It changes over many years with weathering and erosion
Factors such as the type of eruption (explosive or effusive), the composition of the magma, and the presence of glaciers or erosion can all contribute to changing the shape of a volcano. Expansive eruptions can lead to the collapse of the volcano's summit, while erosion can alter its overall profile over time.
No. Weathering will gradually destroy a volcano that has nor erupted for a long time.
yes
Extrusive volcanic features, such as lava flows and volcanic cones, can undergo changes over time due to weathering and erosion. Weathering breaks down the rock material, while erosion removes the material, shaping the landforms. This process can result in the gradual leveling of volcanic cones and altering the appearance of lava flows.
Soil erosion
An island made from a volcano can become smaller over time when the volcano is no longer active due to erosion processes like weathering, waves, and sediment transport. These processes gradually break down the volcanic rock and carry it away, decreasing the size of the island over time.
The Okefenokee Swamp was formed by a combination of weathering and erosion processes over thousands of years, primarily due to the accumulation of organic material and the presence of a low-lying basin. It was not directly created by destructive forces like earthquakes, volcanoes, or impacts of organisms.
That's a very good question.
Yes
This type of volcano is described as dormant. Another level is inactive. This describes a volcano for which there is no record of eruption (unlike dormant), and the volcano's shape and structure is beginning to change due to weathering and erosion.
They both are natural disasters.
