VOLUME= 5cm*10cm*2cm =100cm^3
but density of iron=7.874g/cm^3
mass=7.874g*100 =787.4g
mass of that block = 787.4g
Result rocks poor what heat lave transmit
Answer:
On land, volcanoes form when one tectonic plate moves under another. Water trapped in the rocks in this plate gets squeezed out. This causes some rock to melt. The melted rock, or magma, is lighter than the surrounding rock and rises up.
Hope this helped.
