How does the lithosphere affect human life

Certain geologic conditions help to support human survival:

1. Temperature, Pressure and the Earth- Temperature and pressure are key factors that determine geologic conditions.

2. Density-Density determines whether a substance will float on another substance and thus affects the composition of Earth’s layers.

3.Convection in the Earth- The interior of the Earth is hot. The heating and cooling of the mantle results in convection cells and movement inside the Earth.

4.Plate Tectonics and Volcanism - The Earth’s solid crust is composed of separate sections that constantly move on a partially molten layer of the upper mantle. Major geologic events such as volcanic eruptions result from these plate motions.

5. Carbon Cycle The movement of the crust and mantle allows carbon to be cycled in and out of the atmosphere, stabilizing the surface temperature.

6. Magnetic Field and Life the movement of the liquid outer core as the Earth rotates causes a magnetic field that, with the atmosphere, protects us from solar wind and space particles.

The Earth's structure is an important part of the Earth's system, which is composed of several layers. The movement of these layers affects the atmosphere and biosphere which in turns effects human life.

The investiture controversy began as a power struggle between pope gregory vii (1072–85) and henry iv, holy roman emperor (1056–1106).[2] a brief but significant struggle over investiture also occurred between henry i of england and pope paschal ii in the years 1103 to 1107, and the issue played a minor role in the struggles between church and state in france, as well.by undercutting the imperial power established by the salian emperors, the controversy led to nearly 50 years of civil war in germany, and the triumph of the great dukes and abbots. imperial power was finally re-established under the hohenstaufen dynasty. historian norman cantor:
