What is the name for the principle that brings floating crust into gravitational balance?

Correct Isostasy

Isostasy is the state of gravitational equilibrium between the mantle and the earth's crust. It tries to explain how different topographic heights exists on the earth surface.

It tries to balance all large portions of the earth's lithosphere. It controls the regional elevations of oceans and continents according to the density of rocks.

condensation. good luck!

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
