WHY DOES ICELAND HAVE SEVERAL ACTIVE VOLCANOES? |
BECAUSE IT SITS RIGHT ON THE PLATE MARGIN CALLED "The Mid-Atlantic Ridge". . Here, the molten magma escapes to the surface as the 2 plates move apart. It cools down to form the rocks that make up the island. |
|

WHAT IS A CENTRAL VENT ERUPTION? |
IT IS AN ERUPTION WHERE MAGMA REACHES THE SURFACE THROUGH A SINGLE HOLE. These eruptions produce large amounts of red-hot lava together with ash and rocks blasted high into the air. They form the typical volcano shape. |

WHAT IS A FISSURE ERUPTION? |
IT IS AN ERUPTION THROUGH A LONG CRACK IN THE GROUND. RATHER THAN FORMING A VOLCANO, FISSURE ERUPTIONS TEND TO FORM AN EXTENSIVE FLAT SURFACE CALLED "A PLATEAU". |
|
|
HOW ARE VOLCANOES OF ICELAND MONITORED BY THE SCIENTISTS ON THE GROUND? |
They study patterns of small earthquakes, look for slight bulges on the side of volcanoes, monitor levels of gases in craters. Maps identify possible danger areas and people are evacuated if an eruption is likely. Satellites above the Earth look at volcanoes for minute increases in temperature. |

|
NAME ANY 4 BENEFITS OF VOLCANIC ACTIVITY |
1. About 44% of Iceland's total energy comes from geothermal energy (generates electricity) 2. Some 85% of homes are heated by the natural hot water piped to the houses. 3. Spent water from the heating of houses is used to melt snow on pavements & car parks. 4. Vegetable greenhouses are heated using geothermal energy. |
