WHAT IS VOLCANO? WHAT ARE THE TYPES OF VOLCANOES ?
WHAT IS ACTIVE VOLCANO?
Answers
Answer:
☆A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.
☆Geologists generally group volcanoes into four main kinds--cinder cones, composite volcanoes, shield volcanoes, and lava domes.
☆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. An erupting volcano is an active volcano that is having an eruption... A dormant volcano is an active volcano that is not erupting, but supposed to erupt again.
Explanation:
I hope this answer will help you.
LAVA – Lava is the liquid rock (magma) that flows out of a volcano. Lava glows red hot to white hot as it flows.
ACTIVE VOLCANO – An active volcano is one that erupts regularly.
DORMANT VOLCANO – A dormant volcano is one that has not erupted for many years, although there is still some activity deep inside.
A fissure vent, also known as a volcanic fissure, eruption fissure or simply a fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity. The vent is often a few metres wide and may be many kilometres long. ... Fissure vents are often part of the structure of shield volcanoes.
extinct volacanoes are called dead volcanoe
volcano-- a mountain or hilly tropical ,cronical, having a creter or can't through which lava, rock, fregments, hot vapour and gas are or have been erected from the Earth...
TYPES OF VOLCANOS:
cinder cone.
stravolcano.
Mount rainier.
Mount Fuji.
Lava dome.
Mauna loa.
FOUR MAJOR TYPES:
clinder cone volcano...
composite volcanos...
shield valcanos......
Lava domes.....
