An international research team has discovered why rocks in Earth\u2019s lower mantle suddenly become more viscous at depths between 800-1,200km.<\/h2>\n
The cause of this change is the bridgmanite-enriched rocks that make up most of the Earth’s lower mantle below about 1,000 km. These particular rocks have a much larger grain size than the rocks above them, which results in their high viscosity.<\/p>\n
