The Lizard atmosphere and extreme southerly location being uniquely suitable. This became the Goonhilly satellite earth station, now owned by Goonhilly Earth Station Ltd. Some important developments in television satellite transmission were made at Goonhilly station. A wind farm exists near to the Goonhilly station site. Known as the Lizard complex, the peninsula's geology is the best preserved example of an exposed ophiolite in the United Kingdom. An ophiolite is a suite of geological formations which represent a slice through a section of ocean crust (including the upper level of the mantle) thrust onto the continental crust. The Lizard formations comprise three
Structure of the Earth of the modern value. Seismic measurements show that the core is divided into two parts, a "solid" inner core with a radius of ≈1,220 km and a liquid outer core extending beyond it to a radius of ≈3,400 km. The densities are between 9,900 and 12,200 kg/m in the outer core and 12,600–13,000 kg/m in the inner core. The inner core was discovered in 1936 by Inge Lehmann and is generally believed to be composed primarily of iron and some nickel. Since this layer is able to transmit shear waves (transverse seismic waves), it must be solid. Experimental evidence has
