Billions of years ago. No people were around, then, so there is no record of the event.
yes cinder cone volcano are made from magma
Paricutin Volcano in Mexico is a rare example of a volcano that is entirely made of tephra, which are fragments of volcanic rock ejected during an eruption. It emerged in 1943 from a cornfield and grew rapidly, reaching a height of over 1,300 feet before becoming dormant in 1952.
cinder cone volcano
A Stratovolcano is a steep volcano made mostly of layers of ash, lava and cinders. Stratovolcanoes have a tendency to be very explosive and produce significant quantities of ash.
A cinder cone volcano typically has basaltic lava, which is low in silica content and flows easily. This results in the formation of steep-sided cones made of mostly cinders and volcanic ash.
Mount Parícutin is a cinder cone volcano, not a composite shield volcano. It formed through a single eruption in 1943 and is made up mainly of pyroclastic material such as ash, cinders, and lava flows, typical of cinder cone volcanoes.
Cinder cone
A cinder cone volcano is steep-sided with slopes made of small, jagged rocks that are usually dark in color.
A hot spot volcano is a volcano is one that forms as a result of an extra hot area of the mantle just beneath the crust. Such volcanoes are often far from plate boundaries. A cinder cone volcano is a relatively small volcano with steep slopes made of cinders. The two are not mutually exclusive: some cinder cone volcanoes are associated with hot spots.
Some famous cinder cone volcanoes include Paricutin in Mexico, Sunset Crater in Arizona, and Capulin Volcano in New Mexico. These volcanoes are characterized by their small size and steep-sloped cones composed of loose volcanic fragments known as cinders.
Glassy volcanic fragments with many trapped air bubbles.
A cinder cone volcano is made from particles and globs of lava thrown from a single opening in the crust. This type of volcano has steep sides and is typically smaller in size compared to other types of volcanoes.
