In 1876, Karl Wernicke found that damage to a different part of the brain also caused language problems. This area of the brain (Wernicke's Area), was further back and lower in the brain compared to Broca's area.In fact, Wernicke's area is in the posterior part of the temporal lobe.n 1876, Karl Wernicke found that damage to a different part of the brain also caused language problems.

The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere. The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth. The Mantle . The mantle is the layer located directly under the sima. It is the largest layer of the Earth, 1800 miles thick. The mantle is composed of very hot, dense rock. This layer of rock even flows like asphalt under a heavy weight. This flow is due to great temperature differences from the bottom to the top of the mantle. The movement of the mantle is the reason that the plates of the Earth move!
