Have you recently tried to schedule a meeting with your coworkers and found it difficult to find a time when everyone is available? If this is the case, then you know how precious the time together can be and how important it is to have effective and efficient meetings. To put time spent in meetings into perspective, I often remind myself that while in a meeting, you are really using that time spent multiplied by the number of people in the room.
(plural active volcanos or active volcanoes). ( 1 geology) A volcano that has erupted in the last 10,000 years, not necessarily venting lava or gases now. 2  Link/Cite.
A volcano is a mountain where lava (hot, liquid rock) comes from a magma chamber under the ground. Most volcanoes have a volcanic crater at the top. When a volcano is active, materials come out of it.The materials include lava, steam, gaseous sulfur compounds, ash and broken rock pieces.When there is enough pressure, it causes the volcano to erupt. The pressure blows off the top of the volcano.The magma comes out, sometimes quickly and sometimes slowly.hese volcanoes are formed by low-silica (i.e. basic) lava. Shield volcanoes are built out of layers of lava from continual eruptions (without explosions). Because the lava is so fluid, it spreads out, often over a wide area.
