Density is not something that changes just because we're on earth. Density is a universal concept of how tightly packed the mass of an object is packed.
If you're trying to figure out why gravity is different from planet to planet, which is just caused by the speed of which the planet orbits the sun/object.
Air density is higher near the surface of the Earth. As you climb away from the surface, the pressure decreases.
Cause it depends how close the Earth is to the Sun
The moon's average density is about the same as the density of mantle of the Earth.
yes, its called erosion
Well, the rotation of the earth does cause the wind pattern to change, if the earth stood still, the wind would be straight.
Density does not change regardless of where the object is. It is a constant.
Heat or cool the object and this will cause a density change.
Salt
the earth freezers layers after density stratification which consists of the core, mantle, and crust
It doesn't change earth cause science
gets heavier
The deeper you get into the earth, the more weight you have above you. This results in pressure that increases the density of the material below.
density
yes
mass dose not change on a spaceship
Erosion is something that causes the earth's landforms to change.
The water will be calm, because a change in density causes water to move and can also cause deep water currents
