Mecury, Venus, Earth and Mars are terrestrial planets and are classed as rock planets (molten rock,etc)
In the beginning dust gathered into large bits dust had been converted from gas to dust from the leftovers of the sun's birth.
The heat of the sun melted the dust and moulded it into large rocks (asteroids) consisting 50% magma and lava (hot plasm)
and 40% rock and 10% minerals and chemicals.
The rocks smashed together and finally weighed down on space so heavily that it would create a gravity pocket that gave gravity to the rocks that grouped to melt and mould a planet, Mercury, Venus, Earth and Mars.
The planetary core melted through different chemical reactions until Fe, Feril Iron was made plugging the gravity pocket at the core as the molten magma pushed out and the Earth was quite literally a fire ball before it formed it's skin, the crisp was now crust on all four planets and the crust built up as the magma on the inside cooled just under the crust, this thickened it internally.
Then the four planets faced the great bonbardment. Magma pushed it's way up through craters and plate cracks converting to lava as it comes out the surface, the leak solidified a layer as it cooled making the volcano body larger, as lava spewed down the side it solidified each term making up a large cone until after a few days the volcanos were born on all four planets, although there was about six planets in that area they did not survive and between Mars and Jupiter they smashed to rocks and the asteroid belts were born, Kuiper being mosts famous as well as the Trojans that follow Jupiter around now.
As the volcanos on the planets formed the volcanos crashed down and turned to islands as the steam was sucked into clouds and rain fell, making the sea full of acidic water.
All four planets would of had this including Mars but Mercury being so close to the sun melted water... and so goes on...
There was lots of Jupiters during birth and the core plugged the gravity pocket that was 12x as dense as ours so Jupiter would be 20x1g of 1g of our planet, thus swallowing gas and dust into an extremely thick halo and mass, the moons would have formed like the four main planets were.
Saturn would of been the same as Jupiter but gathered up asteroids, dust and gases this form a disc and halo including moons like Jupiters, the Ice planets of Uranus, Neptune, Pluto would have an ice core plug for the gravity pocket this would form enough flection for ice, water and dust on the planet, with a solid ice core, the planets would of been made from dust and cold gas.
The solar system is born with 9 planets and lots of moons and 9 planetary cores and lots of moon cores.

The Earth's core is actually solid, mostly made of iron and nickel. The liquid magma is in the outer core and lower mantle, not actually at the center. Venus is the only other planet which might have active volcanoes or quakes, but several of the large moons of Jupiter and Saturn have geologic activity. Mars had an active core at one time, but I think it has cooled down.

"Scientists have not until now had any firm evidence whether the core of Mars was solid or liquid, though they had suspected it would be at least partly liquid, and they knew it was mostly iron. The new study finds that at least the outer portion of the core is indeed molten, making it similar to the cores of Earth and Venus. The conclusion is based on three years worth of data showing changes in the orbital characteristics of the Mars Global Surveyor."
so the answer to ur question is yes. its hot in there baby.

All these answers and not one right. It is imperative that there be a heat source within a planet in order for a gravitational field to form. The concept for the formation of a gravitational field is, c2 = E/m. Were gravity not a product, then this force, because it performs work, would have to be being created in all matter at all times. If there were a mass directly identical planet earth, and were it to have no heat energy at all contained within the mass, then it would have no gravitational field at all.

The Earth's core is made molten forms of various metals, not "plasma." Some planets are comprised entirely of gas, while others I'm sure have insides similar to that of Earth.

Plasma is an ionized gas, not a liquid. Liquid rock is called magma/lava.
The inner composition of planets varies from planet to planet. Check wikipedia or something.

the core of our planet Earth is not filled with Plasma it is called Magma and is made of molten rock
as to how other planets are made of the same material when we get to them we may just find the answer to this question all we have at the moment is supposition

Look buddy !!! It is not necessary that other planets have a core too. Many planets are made up of gases only like Jupiter. So u can't be sure about other planets.

I would think so....anything totally solid and subjected to all the pushing and pulling by the sun would soon break apart if not flexible...Nasa recently found volcanoes on Io, a satellite of Jupiter
