• When thick magma and large amounts of gas build
  up under the surface, volcano eruptions can
  happen. They can be explosive, expelling lava,
  rocks and ash into the air. Less gas and more
  thick magma usually mean a less dramatic
  eruption, often causing streams of lava to ooze
  from the vent.

• Mauna Loais Earth's Largest Volcano
• Rising gradually to more than 4 km above sea
  level, Mauna Loa is the largest volcano on our
  planet. The enormous volcano covers half of the
  state of Hawaii and by itself amounts to about 85
  percent of all the other Hawaiian Islands
  combined.
• Mauna Loa is among Earth's most active volcanoes,
  having erupted 39 times.

• About 1,900 volcanoes on Earth are considered
  active, meaning they show some level of activity
  and are likely to explode again. Many other
  volcanoes are dormant, showing no current signs
  of exploding but likely to become active at some
  point in the future. Others are considered
  extinct.

• Venus has more volcanoes than any other planet in
  the solar system. Over 1600 major volcanoes or
  volcanic features are known and there are many,
  many more smaller volcanoes. (No one has yet
  counted them all, but the total number may be
  over 100,000 or even over 1,000,000).

• Volcanoes affect people in many ways, some are
  good, some are not. Some of the bad ways are that
  houses, buildings, roads, and fields can get
  covered with ash. If the ash fall is really heavy
  it can make it impossible to breathe.
• Lava flows are almost always too slow to run over
  people, but they can certainly run over houses,
  roads, and any other structures.
• Some of the good ways that volcanoes affect
  people include producing spectacular scenery, and
  producing very rich soils for farming.
