Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Do cinder cone volcanoes usually erupt explosivley?
no , it is moderate to violent eruption throws such as : volcanic ash, cinders, and lava high into the air .
How often do cinder cones erupt?
normally, only once a year! not very often.
Is hot gases the only thing that come out of a cinder volcano?
No. Cinder cone volcanoes erupt fountains of lava, which is how the cinder cone is built up. Cinder cones that are nearing the end of activity may also produce lava flows.
Which statements is not true about cinder cones?
Cinder cones are typically characterized by their steep slopes and conical shape, formed from the accumulation of volcanic debris such as ash and small rocks. A statement that is not true about cinder cones is that they are the largest type of volcano; in fact, they are generally the smallest and simplest type of volcano compared to shield or stratovolcanoes. Additionally, cinder cones usually erupt only once, while some may have multiple eruptions over time.
What type of volcano has lava that primarily consists of basalt?
Both shield volcanoes and cinder cones primarily erupt basaltic lava.
Are cinder cone volcanoes gentle and long-lasting?
No. Cinder cones usually produce relatively explosive eruptions and are short-lived. Some only erupt for a few years before going extinct.
What is the cornfield that became a volcano?
Mt. Paracutin is fabled to have sprung up overnight in a cornfield. Though it was not this rapid, it did grow very fast. It is a cinder-cone volcano, and is made of ash and cinders. Cinder-cones are the fastest forming volcanoes because they do not need a lot of lava to erupt. Cinder-cones are also the fastest to erode away.
How do cinder cone volcanos erupt?
Cinder cone volcanoes erupt explosively, but not as violently as composite volcanoes.
What are characteristics of a cinder cone?
A cinder cone volcano is constructed from pyroclastic materials ejected from a central vent. These pyroclastic materials which include lava, lahars, tuffs & welded tuffs accumulate to form the cone shape we observe in these tyoes of volcanoes. They generally have slopes ranging between 30 to 40 degrees. Cinder cones are generally small volcanoes and do not exceed 500m in height. Cinder cones erupt Andesitic lava which has a relativley high viscosity meaning it is thick and flows slowly. Because of the viscosity of the lava they erupt fairly explosivley.Cinder cones are very small and has lava that is very active and are very explosive
How often do the cinder cone erupt?
Cinder cones typically have sporadic eruptions, occurring every few hundred to few thousand years. The frequency can vary depending on the geological setting and the magma supply beneath the cone. Some cinder cones show no sign of eruption for thousands of years, while others may have more frequent eruptions.
What type of lava do cinder cones have?
Basaltic. There is more gas content than in most basaltic magma so that when a cinder cone erupts, The pressure builds up and makes the eruption somewhat explosive. Tephra, or dried lava/magma, is shot up, and joined to the volcano making it larger.
