Yes, Europa may be rich in silicates and lightweight water ices. The surface consists of many systems of cracks, and ridges, running for thousands of miles, about 10–25 mi (16–40 km) in width. There are few elevations, and the surface is remarkably free from craters. The ice surface makes the satellite(or moon)of Jupitor one of the most reflective bodies in the solar system. Geologic activity is thought to heat the ice under the surface to near-liquid state, allowing it to gush through in volcanoes of slush and water. It is likely that liquid oceans exist on Europa at depths more than 6 mi (10 km) below the surface, kept liquid by geothermal activity and tidal action. This is suggested by the variable Europan magnetic field observed by the Galileo spacecraft. It is not inconceivable that simple life may exist in the Europan oceans, much in the same way as in Earth's oceans lifeforms congregate near thermal vents.

Europa has lines all over it. This is from the icy surface cracking and water spewing out of the cracks, then freezing again. The lines are called double ridges.

Does scientists think that Europa may have an icy surface an underground ocean active volcanoes or an atmosphere?

Of these four choices, out current understanding of Europa (and remember, everything is subject to change in the light of more recent discoveries) indicates that Europa may have large liquid oceans under a layer of ice. There are interesting surface features that appear to be large ridges; these might have been formed by cracks in the icy surface, and liquid or vapor escaping to the surface - and then freezing into ridges as the cracks close.


What is the name of an icy satellite of Jupiter?

Europa is one of Jupiter's icy satellites (moons)


Could there be life on Jupiter's moon Europa?

Europa is the fourth largest moon of Jupiter. Scientists think that life may exist on Europa because there is evidence that liquid water may exist beneath its icy surface. Europa is pushed and pulled by the high gravity of Jupiter as well as by the gravity of Jupiter's other moons. This makes Europa expand and contract and causes it to heat up and this heat may cause some of Euorpa's icy crust to melt under the surface. So, there may be lakes and oceans of liquid water on Europa. Water is a major requirement for life. If there is liquid water on Europa, there may be life.


What makes europa unique to other moons?

europa's atmosphere consists of oxygen. also, under it's icy surface, is an ocean of liquid water.


Could Europa have life?

Possibly. Europa has an ocean of liquid water under its icy crust, which might have light.


Which of Jupiter's moons possibly contains a liquid ocean under its surface?

Europa is the moon that could possibly contain a liquid ocean under its icy surface, and it could possibly be liquid water, or H2O!


Can Eurpora have an icy surface?

It is almost certain that most of Europa's surface is covered with ice. More than this, because the interior of Europa is wracked by tidal forces from Jupiter and the rest of the moons of Jupiter, it is very likely that, despite the low temperatures on the surface, Europa has a great deal of liquid water underneath the icy surface as the temperature there would be very moderate. If so, then the possibility of life there of some sort is high. This was mooted in Arthur C Clarke's 2001: A Space Odyssey and its subsequent sequals.


Describe why scientist think life may exist on Europa?

The movement of segments of Europa's icy surface, akin it Earth's tectonic plates, indicates that part of the interior is liquid water.


Why do scientist think that Europa may have the conditions to support life?

The tectonic plate-like movement of its icy surface and various measurements indicate that Europa has a subsurface ocean of liquid water. Liquid water is considered the most important factor for a world's ability to have life.


Scientsts think that the moon europa may have what?

Is there water on Jupiter's moons?

yes europa has an icy surface but underneath theres underwater volcanoes that warms the ocean. plus theres some oxigen which now scientist belive that there is aquatic life there.


What suggests that there might be liquid water on Europea?

The icy surface of Europa appears to be broken up into segments not unlike the tectonic plates on Earth. The surface appears, in geologic terms, to be rather young. If the surface is moving as we have found, then there is most likely a liquid layer under the ice.


Which vital substance does the moon europa have?

What is the temperature on Europa?

The temperature on the surface of Europa is between 50 and 125 degrees Kelvin.
