What does europa smell like?
Nothing it has no atmosphere above the surface and below the surface there may be water oceans, however, human beings cannot smell underwater.
Where do volcanoes that are far from the margins of the tectonic plates appear?
These volcanoes are believed to be above local 'hot spots' on the surface. Hawaii would be the prime example. Most volcanoes occur above the subduction zones at a merging plate boundary. But volcanoes also appear directly at the expanding junction of a pair of plates. Iceland, and some of the South Atlantic islands are examples of this.
How much of the Earths surface is made from volcanoes?
Lava being the unsolidified molten rock material deposited on the surface of Earth? A fraction of a fraction of a fraction of a percent. As defined as a solidified rock, the percentage of Earth's crust is over 66% hardened lava, in the form of basalt.
Are the active Hawaiian volcanoes situated directly above a major boundary between two of the Earth's largest tectonic plates?
No. The Hawaiian Islands are situated directly above what's called a "hot spot." A hot spot is an area under the tectonic plate where magma gathers, gradually gaining pressure until it's released above the surface forming volcanoes and subsequently islands.
Which of the above of boundaries can produce volcanoes?
convergent
What are islands arc volcanoes?
Island arc volcanoes are islands that form in chains underwater and emerge above the surface for form a series of islands.
Is there a place where it is always above 100 degrees Celsius?
Yes. Surface of the sun. Volcanoes and volcanic vents.
What is likely to occur on the earth's surface where it lies above the edges of crustal plates?
volcanoes,earthquakes,mountains

What is volcano islands?
Volcano Islands are the remains of dormant or still active volcanoes that have formed islands of land above the surface of the sea.
Are there volcanoes oceans earthquakes on mercury?
None of the above. By all evidence obtained so far, satellite mappings, etc, Mercury as an "active" planet closed up shop long ago.
What is the name for magma that has erupted?
Lava. Note: Magma cant erupt, volcanoes do. Magma is just the word for molten rock beneath the earths surface, lava is for molten rock above the earths surface.
How are underwater volcanoes different from volcanoes that are above sea level?
jks
Is the vast majority of the world's volcanoes are above sea level?
The vast majority of the world's volcanoes are above sea level.
What is a level of the ocean's surface?
I Want to now what the level of the ocean's surface is
Why does surface runoff flow towards the ocean?
Because the oceans are at sea level and the rivers are always above sea level, meaning that water flows downhill.
