What is a volcano Britannica?
volcano, vent in the crust of Earth or another planet or satellite, from which issue eruptions of molten rock, hot rock fragments, and hot gases. In other cases, entrapped gases tear the magma into shreds and hurl viscous clots of lava into the air.
What do Hornitos mean?
: a low oven-shaped mound in volcanic regions that emits smoke and vapors.
What is a volcano kid friendly definition?
A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.
What is the 5 description of volcano?
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. In an eruption, gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lava flows, hot ash flows, mudslides, avalanches, falling ash and floods.
What causes a volcano?
Most of the world’s volcanoes are found around the edges of tectonic plates, both on land and in the oceans. On land, volcanoes form when one tectonic plate moves under another. When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
Is a Hornitos?
Hornitos are conical structures built up by lava ejected through an opening in the crust of a lava flow. Hornitos are similar to spatter cones but are rootless, meaning they were once a source of lava but that source was not directly associated with a true vent or magma source.
How much alcohol is in Hornitos?

What can you say about volcano?
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. In an eruption, gases and rock shoot up through the opening and spill over or fill the air with lava fragments. More than 80% of the earth’s surface is volcanic in origin.
What is volcano explain?
What is a volcano? Volcanoes are openings, or vents where lava, tephra (small rocks), and steam erupt on to the Earth’s surface. Many mountains form by folding, faulting, uplift, and erosion of the Earth’s crust. Volcanic terrain, however, is built by the slow accumulation of erupted lava.
What are the 7 parts of a volcano?
A cross section of a composite volcano reveals alternating layers of rock and ash: (1) magma chamber, (2) bedrock, (3) pipe, (4) ash layers, (5) lava layers, (6) lava flow, (7) vent, (8) lava, (9) ash cloud. Frequently there is a large crater at the top from the last eruption.
What are 10 facts about volcano?
Top 10 Facts About Volcanoes
- Volcanoes are openings of the Earth’s surface.
- The word volcano comes from the word ‘vulcan’.
- Volcanoes can be active, dormant or extinct.
- The liquid inside the volcano is called magma.
- Lava is the liquid that is expelled from the volcano.
- Lava is very, very hot!
How tall is a hornito in a volcano?
(Photo: Tom Pfeiffer) Hornito (Spanish) = “Little oven”. Volcanic hornitos are small (usually a few meters high) rootless spatter cones that form on the surface of a (usually basaltic pahoehoe) lava flow.
What is the meaning of the word hornito?
/hɔrˈni toʊz; Spanish ɔrˈni tɔs/. Geology. a low oven-shaped mound of congealed lava, common in some volcanic districts, emitting hot smoke and vapors in the final stages of activity.
How are Hornitos formed in a lava flow?
Hornito (Spanish) = “Little oven”. Volcanic hornitos are small (usually a few meters high) rootless spatter cones that form on the surface of a (usually basaltic pahoehoe) lava flow. A hornito develops when lava is forced up through an opening in the cooled surface of a flow (a skylight) and then accumulates around the opening.
What is the kids definition of a volcano?
Kids Definition of volcano. 1 : an opening in the earth’s crust from which hot or melted rock and steam erupt. 2 : a hill or mountain composed of material thrown out in a volcanic eruption.
