Earth Cross Section

The earth s crust ranges from 5 70 kilometres 3 1 43 5 mi in depth and is the outermost layer.
Earth cross section. Dashed lines marked s are shear waves. Solid lines marked p are compressional waves. The radius of the core is just over half the radius of the earth.
Any cross section passing through the center of an ellipsoid forms an elliptic region while the corresponding plane sections are ellipses on its surface. The cross section of the earth is a visualization of the composition of the earth in geological terms. The conic sections circles ellipses parabolas and hyperbolas are plane sections of a cone with the cutting planes at various different angles as seen in the diagram at left.
The outer core is liquid and the inner core is solid. Total solar power striking the earth the radius of the earth is re 6400 km so the cross sectional area of the earth that can absorb solar radiation is a r2 e 120 10 6 km2 1 2 108 km2 1 2 1014 m2. A cross section showing the earth s structure.
At the top of earth s atmosphere the solar insolation i is deļ¬ned as the total solar power per square meter striking a surface oriented exactly perpendicular to the. Convection hot spot. The planet earth is an immensely complicated and dynamic system with many different physical and chemical properties.
Tectonic plates and boundary types. Most human experience of the earth is limited to the surface however with the deepest human endeavor made in 2012 to depths of 11 km in the mariana s trench. Cross section of the whole earth showing the complexity of paths of earthquake waves.
A cross section of the earth showing the sub surface layers that are being mapped. A cross section of a polyhedron is a polygon.
