What is the cause of volcanic activity in Iceland?
There are two causes of earthquakes in Iceland. First, it lies on a plate boundary. Movement of the tectonic plates drives some earthquakes. Iceland is volcanically active. The movement of magma underground causes some earthquakes.
Why does iceland volcano lie there?
There are many volcanoes in Iceland because the country is situated on the Mid-Atlantic Ridge where new oceanic crust is being formed all the time. Iceland is one of the few countries in the world which is growing in size every year.
Why can Iceland Japan and New Zealand make use of geothermal energy?
All three are volcanic islands with thermal vents reaching all the way down to the mantle.
Why does Iceland have so much geothermic energy?
Because it sits on top of a spreading fault line which pushes magma upwards heating all the rocks around it this also explains icelands volcanic activity
Which terrestrial planets have had volcanic activity at some point in their histories?
Mercury, Venus, Earth, and Mars have all had volcanic activity at some point in their histories. Volcanic features such as lava flows, volcanic mountains, and calderas can be found on these terrestrial planets, indicating their volcanic past.
How does the presence of volcanic activity of the people in Australia?
It doesn't really, apart from magma moving all the continents Australia is unaffected by any Volcanic activity.
What would happen if there was no volcanic activity?
we would all die
What would happen if there was no volcanic activity on earth at all?

What forms the volcanic island country of Iceland?
Iceland itself is in a very unique geologic setting on earth. There are a combination of forces that are forming and constantly changing Iceland. First of all Iceland sits on top of the mid-atlantic ridge, which is causing the sea floor to spread apart making new land where it is pulling apart. This is a volcanic driven force that causes the sea floor spreading and magma does erupt in the areas that are spreading. The other major factor that is causing the unusually large amount of volcanic activity at Iceland is that it is also on top of a hotspot. Similar to Hawaii, for some reason there is a very hot section of the earths crust underneath Iceland that causes a large amount of magma to form, this creates the volcanoes that are seen in Iceland.
How were the hawaiian islands made?
They were all produced by volcanoes.
Is there any evidence of volcanic activity on Jupiter?
nope no volcanic activity on Jupiter because it's a gas giant so is Saturn, Neptune, and Uranus. Just remember that the planets behind the belt are all gas giants and none of them have volcanic activity because there made out of gas!
Which countries have scoria?
Scoria, a type of volcanic rock, can be found in many countries with volcanic activity, such as Japan, New Zealand, Iceland, and Italy. It is commonly used in landscaping and construction due to its lightweight and porous nature.
