Do the materials toward the earths center have less mass than those on the surface?

The weight of an object would decrease as you go towards the centre of the earth, since the force of gravity decreases with depth and weight is mass x g. It would eventually become zero in theory. The mass of an object would stay the same in theory.
Another way of looking at the question is considering density, this increases with depth to huge amounts at the core. The mass of a given amount of material would remain the same, but the pressure would crush it into a smaller space, increasing the density.

Why do partly molten materials rise toward earths surface?
Magma is molten or partially molten rock beneath the earth's surface and is lighter than the surrounding rock so it tends to rise. As it moves upward, the magma encounters colder rock and begins to cool.
What causes hot plasticlike rocks in the asthenosphere to rise toward the earths surface?
The rock in a rising convection current is hotter and more buoyant than the surrounding rock, causing it to rise.
Are most volcanoes on land caused by the earths plates moving away from each other or moving toward each other?
all volcanoes are caused by the earths plates moving toward each other and that is called convergent boundaries.
Where does magma form before it moves toward Earth's surface?
from rocks being melted in the earths core, it then gets pushed up and the pressurre builds, the a volcanic erupiton takes place due to the pressure from the outer core/mantle, strange but true
What is the frontal surface of the body called?
The frontal surface of the body is the anterior or ventral surface of the body. Accordingly, the terms "anteriorly" and "ventrally" specify a position closer to--or toward--the frontal surface of the body.
Does pressure increase from earths surface toward the center of earth?
Yes.
Why does heat from earths center flow toward the surface?
it flows because if convection currents
What pulls objects toward earths surface?
Gravity pulls the earth and anything on its surface together, toward each others' centers.This is important to understand:-- There is a pair of gravitational forces between you and the Earth.-- One force pulls you toward the center of the Earth.The other one pulls the Earth toward the center of you.-- The forces are equal.Your weight on Earth is the same as the Earth's weight on you.
Where does magma form before it moves toward the earths surface?
in the mantle above the slab
Heat from the earths center flows toward the suface because why?
Heat from the Earth rises to the surface because heat rises. Heat rises because it is energy and the atoms are looking for more space to move freely in.
Earths surface winds blow from regions of higher what?
Air pressure toward regions of lower air pressure
When two forces acting on an object are equal they are?
Everything gets pulled down toward the earths center because of this force
How did rock affect the formation of earths layers?
As the earth formed, the heavier, more dense elements sunk toward the center, while the lighter, less dense ones stayed near the surface. The result was layers of rocks of similar density.
How does the tempiture change as you go from the surface toward te center of the ea rth?
dont kno
Magma tends to rise toward earths surface?
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
Is this statement true or false all objects fall toward the center of the earth?
Actually they don't they fall on towards Earths crust.
Why do less dense compounds make up earths crust while the densest compound make up the earths core?
because the heavier elements are pulled toward center of the earth by gravity
