To form a ring system that is made of rocks and boulders and other debris, a large gravitational field is necessary to hold such small objects in orbit around the planet. Mercury is a small planet - too small to form such a system. If it did attract some passing debris, its proximity to the Sun would mean that the material would soon be stripped away. It is also probably for this reason that neither Mercury nor Venus has any moons. Only when the Sun's gravity has less influence do the planets have moons.
The other possible constituent of rings is ice, which makes up most of Saturn's rings. Volatiles such as water ice and frozen gases cannot exist in orbits close to the Sun.
Mercury does not have moons or rings because its close proximity to the Sun and its small size make it difficult for it to capture or maintain moons or attract and sustain a ring system. Additionally, any moons or rings that may have formed would likely be disrupted by the strong gravitational influence of the Sun.
Technically, in a way, the Sun does have "moons".
Moons are small planetary bodies that are caught in the gravitational orbit of a larger celestial body, such as a planet. All the planets and bodies in our solar system orbit the sun, therefore, technically, all the planets in the solar system are moons to the sun.
But, the sun does not have a moon per se because the intense heat of the sun would just vaporise it.
The same applies to rings. Rings are caused by moon collisions. When a moon collides with another moon, it shatters. The resulting debris orbits the planet, creating a ring of rocks. If the sun had a ring, it would also vaporise it.
In short - the sun is too hot.
I personaly think that there is no volcanic activity on mercury because the core has cooled down.
They don't have rings because the Sun's heat and solar wind blew the rings away.
There are no volcanoes currently located on the planet Mercury and therefore no volcanic activity. It is believed that this planet used to have volcanoes.
While I cant say for sure I think that it could potentially. For how close to the sun it is, and how hot it is, im sure it has a molten core that shifts around the solid rock above.
The moon does not have a liquid magma core like the Earth.
This liquid core is needed to create Volcano's.

Name the planet or planets that have neither rings nor moons?
Mercury and Venus are the two planets that have neither rings nor moons. Earth and Mars each have moons, and the gas giants all have rings and moons.
Does Venus have any moons or rings?
No. Venus is devoid of rings and moons. Mercury is the only other of the eight major planets that has no moons. Both planets are closer to the Sun than Earth is.
Does Mercury have anything orbiting it?
Mercury does not have any natural satellites or moons orbiting around it. It is the only planet in the solar system apart from Venus that does not have any moons.
How many satellites and rings Mercury have?
Mercury has no natural satellites (moons) and no rings. It is a small, rocky planet located closest to the Sun in our solar system.

Does mercury have ten rings and fifteen moons?
Mercury has no moons nor rings.
Can you see rings on Mercury?
There are no rings or moons on Mercury.
Are there moons or rings on mercury?
yes,there is moons and rings on mercury. hi whoever reads this this is not true
How many moons and rings in Mercury?
Mercury has no moons and no rings. It is a small, rocky planet with no natural satellites orbiting around it, and it lacks the necessary conditions to support the formation of planetary rings.
Does mercury have any moons or any rings?
Mercury has no moons, and no rings have been observed. Either moons or rings may have existed, but this is not considered a likely possibility.
Does mercury have presence of moons or rings?
No
