No. You need high density material and mass to create a strong gravitational pull.

yepp..! gravity comes from the core.. core is predicted to have a liquid layer on the outside.. In side it is belived to be made of metal..
The styraphome would most probably get crushed up to the size of the core.. There will be no such thing as the teorie of plate techtonice due to the lack of an asthenosphere and lithosphere.. Oh yeah dont forget the inner mantel... That would not exist either... Bottom line>> Core creates magnetic pulls that make gravity.. If the mantel, lthosphere, astenosphere was all made of styrofoam all these layers will definately crush due to the existance of the core..

the gravitational force on a planet is due to the attraction of the masses of the planet and the mass which interacts with that planet. If the earth were composed with Styrofoam, its density and its mass would be lower. So, the gravity would be lower

life would never be the same with styro-earth..
styrofoams are so so light... we might as well be magnetted to the sun and burn....
the law of universal gravitation states that gravitation depends on masses of two objects and the distance between those two objects squared....

Yes, I believe it would be the same.
The famous experiment was done by an astronaut on the moon (where there is no atmosphere to cause wind resistance). The astronaut dropped a hammer and a feather at the same time from the same height. The fell at the same speed and landed at the same time. That proved that gravity affects light and heavy objects exactly the same.

no, the gravitational force is based on the mass of the earth, if it were made of something lighter, the force would be less

No, the Mass of the object is what determines the objects Gravity Field.

gravitational force of the earth is proportional to earth mass:
F=G * m1 * m2 / r^2
