Inferred Properties of Earth’s Interior: Inferred Properties Of Earth’s Interior Answer Key

The conditions within Earth’s interior are extreme, with high temperatures, immense pressures, and unique chemical compositions. These properties have a profound influence on the behavior and characteristics of the materials that make up our planet’s interior.

Temperature within Earth’s interior increases with depth, reaching approximately 5,700 Kelvin at the core-mantle boundary and over 6,000 Kelvin at the center of the core. This extreme heat is generated by radioactive decay, residual heat from Earth’s formation, and convection currents in the mantle.

Pressure also increases significantly with depth, reaching over 3.6 million atmospheres at the core-mantle boundary and an estimated 4 million atmospheres at the center of the core. These extreme pressures alter the behavior of materials, affecting their density, elasticity, and phase transitions.

Density varies throughout Earth’s interior, with the densest materials concentrated in the core. The core’s density is estimated to be around 13 grams per cubic centimeter, while the mantle’s density ranges from 3.5 to 5.5 grams per cubic centimeter, and the crust’s density averages around 2.7 grams per cubic centimeter.

Evidence supporting the inferred properties of Earth’s interior comes from various sources, including seismic waves, gravity measurements, and laboratory experiments. Seismic waves provide information about the density and elasticity of Earth’s layers, while gravity measurements reveal variations in density and mass distribution.

Laboratory experiments under extreme conditions simulate the conditions within Earth’s interior and provide insights into the behavior of materials under such extreme conditions.
