Why are there no impact craters on the surface of Io?

Why are there no impact craters on the surface of Io?

18) Why are there no impact craters on the surface of Io? Jupiter’s strong gravity attracted the planetesimals more strongly than Io and thus none landed on its surface. C) Io did have impact craters but they have all been buried in lava flows.

Why does Io have no impact craters quizlet?

There are no impact craters on Io because of the active volcanoes on the moon and the lava smooths out the surface where the impact craters hit.

Why are no craters seen on Io and few seen on Europa?

Why are no craters seen on Io and few seen on Europa? On Europa, the icy surface is constantly shifting and if it is struck, it just becomes water and freezes again or becomes gas. Io is very volcanic, so it is constantly being resurfaced. The gas moves much slower on Titan, so it is unable to escape.

What does the lack of craters on Io tell us?

What does the lack of craters on Io tell us? Io’s surface must be very young. not? Icy moons were formed with more radioactive material than small terrestrial planets.

Why is Saturn almost as big as Jupiter despite its smaller mass?

Why is Saturn almost as big as Jupiter, despite its smaller mass? Jupiter’s greater mass compresses it more, thus increasing its density. All have cores of about the same mass, but differ in the amount of surrounding hydrogen and helium.

Why do the Jovian planet interiors differ Group of answer choices?

Why do the jovian planet interiors differ? Accretion took longer further from the Sun, so the more distant planets formed their cores later and captured less gas from the solar nebula than the closer jovian planets. Different layers represent clouds made of gases that condense at different temperatures.

Why is IO more volcanically active?

Why is Io more volcanically active than our moon? Io has a different internal heat source. Io’s elliptical orbit is necessary to its tidal heating. This elliptical orbit, in turn, is a result of the orbital resonance among Io, Europa, and Ganymede.

Can we breathe on Europa?

Europa has a thin oxygen atmosphere, but it is far too tenuous for humans to breathe. From the surface of Europa, Jupiter appears 24 times larger than the moon appears in our sky. Europa’s magnetic field shields its surface from Jupiter’s deadly radiation.

Does Europa have gravity?

1.315 m/s²
Europa/Gravity

Why is there no life on Titan?

Titan is not a pleasant place for life. It is far too cold for liquid water to exist, and all known forms of life need liquid water. Titan’s surface is -180°C.

Why are there no impact craters on Jupiter?

Jupiter’s strong gravity attracted the planetesimals more strongly than Io and thus none landed on its surface. It is too small to have been bombarded by planetesimals in the early solar system. Io’s thick atmosphere obscures the view of the craters. Io did have impact craters but they have all been buried in lava flows.

Which is true about Io in the Solar System?

Which statement about Io is true? It is the only moon in the solar system with a thick atmosphere. It is thought to have a deep, subsurface ocean of liquid water. It is the largest moon in the solar system. It is the most volcanically active body in our solar system. It is the most volcanically active body in our solar system.

Why is Io the closest moon to Jupiter?

Io exhibits synchronous rotation, meaning that its rotation period and orbital period are the same. Io orbits Jupiter in the Io torus, and therefore has a surface that is bombarded by many charged particles. Io is the closest to Jupiter of Jupiter’s large moons.
