What causes volcanic activity on Io?

The volcanic activity is a result of Io being stretched and squeezed as it orbits Jupiter. Io’s rock surface bulges up and down by as much as 100 meters (328 feet) during the process. This affects Io’s volcanic activity in a similar way to which Earth’s oceans react to the moon.

How volcanoes on Io are formed?

Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the moon’s surface. … First predicted shortly before the Voyager 1 flyby, the heat source for Io’s volcanism comes from tidal heating produced by its forced orbital eccentricity.

What causes the high volcanic activity of Io quizlet?

What is the cause of Io’s volcanic activity? — Jupiter’s gravity causes Io’s volcanic activity. Because Io orbits very close to Jupiter, Jupiter’s huge gravitational field exerts strong tidal forces on the moon.

What mechanism is most responsible for generating the internal heat of Lo that drives the volcanic activity?

What mechanism is most responsible for generating the internal heat of Io that drives its volcanic activity? Tidal heating, it arises from effects of tidal forces exerted by Jupiter.

What causes Io to be so active geologically quizlet?

Io must be made of a substance that traps heat better, so it has still retained all of its initial internal heat from its formation. Gravitational tidal heating is stronger on Io than any other moon in the Solar System, providing a source of heat that causes its high level of geological activity.

Why is Io geologically active?

With over 400 active volcanoes, Io is the most geologically active object in the Solar System. This extreme geologic activity is the result of tidal heating from friction generated within Io’s interior as it is pulled between Jupiter and the other Galilean moons—Europa, Ganymede and Callisto.

What mechanism is most responsible for generating the internal heat of Lo that drives the volcanic activity quizlet?

What mechanism is most responsible for generating the internal heat of Io that drives the volcanic activity? Tidal heating.

What mechanism is most responsible for generating the internal heat of some of the Jovian moons?

In a process called tidal heating, gravitational tugs from Jupiter’s moons and the planet itself stretch and squish the moons enough to warm them. As a result, some of the icy moons contain interiors warm enough to host oceans of liquid water, and in the case of the rocky moon Io, tidal heating melts rock into magma.

What mechanism provides the energy that drives Io’s volcanoes?

Although there is general agreement that the cause of the heat as manifested in Io’s many volcanoes is tidal heating from the pull of gravity from Jupiter and its moon Europa, the volcanoes are not in the positions predicted with tidal heating. They are shifted 30 to 60 degrees to the East.

What is the Cassini division of Saturn’s rings?

The Cassini Division is a region 4,800 km (3,000 mi) in width between Saturn’s A ring and B Ring. It was discovered in 1675 by Giovanni Cassini at the Paris Observatory using a refracting telescope that had a 2.5-inch objective lens with a 20-foot-long focal length and a 90x magnification.

What atmospheric constituent is responsible for the blue color of Uranus and Neptune?

Neptune’s atmosphere is made up predominately of hydrogen and helium, with some methane. The methane is part of what gives Neptune its brilliant blue tint, as it absorbs red light and reflects bluer colors. Uranus also has methane in its atmosphere, but has a duller shading.

What is the most important reason why an icy moon is more likely?

What is the most important reason why an icy moon is more likely to be geologically active than a rocky moon of the same size? Ice has a lower melting point than rock.

What caused Cassini division?

The Cassini division is caused by the pull of one of Saturn’s moons called Mimas. A ring particle in the Cassini division would go around Saturn twice for every time Mimas goes around once; this is called a “2:1 resonance orbit”.

What causes the Cassini gap in the rings of Saturn?

The gaps are produced by the gravitational pull of one or more of Saturn’s many moons on the tiny particles in the rings. For the Cassini gap, the moon Mimas is responsible for clearing out any material in the region.

What causes Saturn to have rings?

Rings. Saturn’s rings are thought to be pieces of comets, asteroids, or shattered moons that broke up before they reached the planet, torn apart by Saturn’s powerful gravity. They are made of billions of small chunks of ice and rock coated with other materials such as dust.

What is the Cassini Solstice Mission?

The Cassini mission entered its second extended mission, called the Cassini Solstice Mission, in September 2010. This extension enables scientists to study seasonal and other long-term weather changes on the planet and its moons.

Can you walk on the rings of Saturn?

Saturn’s rings are almost as wide as the distance between the Earth and the moon, so at first glance, they seem like an easy place to land and explore on foot. … But if you were able to hike on one of Saturn’s outermost rings, you’ll walk about 12 million kilometers to make it around the longest one.

Can we see Saturn rings with naked eyes?

It is fairly easy to see with the naked eye, although it is more than 886 million miles (1.2 billion kilometers) from Earth. Plus, its rings can be observed with a basic amateur telescope—surely a sight you won’t forget!

What was the Cassini mission and what did it accomplish?

The Cassini spacecraft orbited Saturn from June 30, 2004, until Sept. 15, 2017, when the probe ended its life with a plunge into the ringed planet’s atmosphere. The mission is known for discoveries such as finding jets of water erupting from Enceladus, and tracking down a few new moons for Saturn.

What did Huygens probe discover on Titan?

During this period, the spacecraft discovered two new moons, Daphnis and Anthe. It also uncovered much valuable data about Titan, including the first radar images of the moon’s surface taken during its Oct. 27, 2004, flyby.

What was Cassini’s mission What instruments did it include?

This set included both optical and microwave sensing instruments including cameras, spectrometers, radar and radio. The fields and particles instruments took “in situ” (on site) direct sensing measurements of the environment around the spacecraft.

What important discoveries did Cassini make?

Cassini’s long mission enabled us to observe weather and seasonal changes on another planet. Cassini revealed Saturn’s moons to be unique worlds with their own stories to tell. Cassini showed us the complexity of Saturn’s rings and the dramatic processes operating within them.

What were Cassini major achievements?

Other accomplishments of Cassini include being the first to observe four of Saturn’s moons — Iapetus (1671), Rhea (1672), Tethys (1684) and Dione (1684) — which he called Sidera Lodoicea, or Louisian Stars, after the French king.
