serp2000 (42108) 2015-08-30 03:26:22During the Permian, all the Earth's major landmasses were collected into a single supercontinent known as Pangaea. Pangaea straddled the equator and extended toward the poles, with a corresponding effect on ocean currents in the single great ocean ("Panthalassa", the "universal sea"), and the Paleo-Tethys Ocean, a large ocean that was between Asia and Gondwana. The Cimmeria continent rifted away from Gondwana and drifted north to Laurasia, causing the Paleo-Tethys to shrink. A new ocean was growing on its southern end, the Tethys Ocean, an ocean that would dominate much of the Mesozoic Era. Large continental landmasses create climates with extreme variations of heat and cold ("continental climate") and monsoon conditions with highly seasonal rainfall patterns. Deserts seem to have been widespread on Pangaea. Such dry conditions favored gymnosperms, plants with seeds enclosed in a protective cover, over plants such as ferns that disperse spores. The first modern trees (conifers, ginkgos and cycads) appeared in the Permian.
Three general areas are especially noted for their extensive Permian deposits – the Ural Mountains, China, and the southwest of North America, where the Permian Basin in the U.S. state of Texas is so named because it has one of the thickest deposits of Permian rocks in the world.

The stage affords visitors a nice view of the numerous cherry and maple trees below that erupt in a sea of color in spring and fall, as well as of the city of Kyoto in the distance. The main hall, which together with the stage was built without the use of nails, houses the temple's primary object of worship, a small statue of the eleven faced, thousand armed Kannon.

The densely forested mountains of the region still occupy 96% of all land in the area, and prior to the introduction of heavy earth-moving machinery, the narrow bands of flat lands running the length of the river valley limited the area available for agriculture and homestead development. The upper storeys of the gasshō houses were usually set aside for sericulture, while the areas below the first (ground) floor were often used for the production of nitre, one of the raw materials needed for the production of gunpowder.
