What is the cause of volcanic activity on Jupiter's Moon Io?

Answer 1

Because it contains allot of elemental sulphur in its makeup (which has a low melting point) and because the gravity of Jupiter distorts it as it orbits Jupiter in an elliptical orbit (this is the source of the energy).

Answer 2

Yes, it is true. Because the gravitational force decreases with distance of the side of Jupiter. The shots of Io revealed seven active volcanic volcanoes.

Edit: That's roughly the answer, but it's not very clear. Jupiter's gravitational effect is large because the moon is so close.

Also the side of Io nearest to Jupiter experiences a bigger force than the

far side. Io always has the same face to Jupiter, just like our Moon.

What's really important is that Io has a fairly "eccentric" orbit, meaning

its distance from Jupiter changes quite a lot. This leads to changes in the

gravitational effects, causing the inside of Io to "flex". That's what makes

the volcanoes.

So, the simple answer to the question is "yes". I'm sorry, but I can't

make the explanation any shorter.

Answer 3

The tidal heating produced by Io's forced orbital eccentricity has led the moon to become one of the most volcanically active worlds in the Solar System, with hundreds of volcanic centres and extensive lava flows. During a major eruption, lava flows tens or even hundreds of kilometres long can be produced, consisting mostly of basalt silicate lavas with either mafic or ultramafic (magnesium-rich) compositions. As a by-product of this activity, sulfur, sulfur dioxide gas and silicate pyroclastic material (like ash) are blown up to 200 km (120 mi) into space, producing large, umbrella-shaped plumes, painting the surrounding terrain in red, black, and white, and providing material for Io's patchy atmosphere and Jupiter's extensive magnetosphere.

Answer 4

Tidal heating causes the volcanic activity on Jupiter's moon Lo. It is the heating of the interior of one planetary body caused by stresses induced from the gravitational pull of another.

Answer 5

Jupiter's moon Io is volcanically active due to Jupiter's gravity. Jupiter's gravity pulls and squeezes on Io keeping it internally molten and active from the friction.
