Title: Climate of Pennsylvania
Content:  The climate of Pennsylvania is diverse due to the multitude of geographic features found within the state. Straddling two major climate zones, the southeastern corner of Pennsylvania has the warmest climate. A portion of Greater Philadelphia lies at the southernmost tip of the humid continental climate zone, with the city proper being in the humid subtropical climate zone. Still, Philadelphia features colder, snowier winters than most locations with a humid subtropical climate. Moving west toward the mountainous interior of the state, the climate becomes markedly colder, the number of cloudy days increases, and winter snowfall amounts are greater. Using the January freezing isotherm, the humid subtropical climate (Cfa) only exists in parts of Greater Philadelphia and low-lying areas of the lower Susquehanna Valley from Harrisburg downriver. Pennsylvania's hardiness zone ranges from 5a in high-elevation areas to 7b in parts of Delaware and Philadelphia Counties.

Title: Pennsylvania
Content:  Pennsylvania (, elsewhere ; Pennsilfaani), officially the Commonwealth of Pennsylvania, is a landlocked state spanning the Mid-Atlantic, Northeastern, and Appalachian regions of the United States. It is bordered by Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and New Jersey to the east. Of the 50 U.S. states, Pennsylvania is the 33rd-largest state by area, and the fifth-most populous, with over 13 million residents as of 2020; it is subsequently the ninth-most densely populated state. Nearly half the population is concentrated 
Title: Geography of Pennsylvania
Content:  Pennsylvania has three general climate regions, which are determined by altitude more than latitude or distance from the oceans. Most of the state falls in the humid continental climate zone. The lower elevations, including most of the major cities, has a moderate continental climate (Köppen climate classification Dfa), with cool to cold winters and hot, humid summers. Highland areas have a more severe continental climate (Köppen Dfb) with warm, humid summers and cold, more severe and snowy winters. Extreme southeastern Pennsylvania, around Philadelphia borders into a humid subtropical climate (Köppen Cfa), with milder winters and hot, humid summers. Precipitation is abundant throughout the state, as the primary climatic influences are the Atlantic Ocean and the Gulf of Mexico, plus Arctic influences that cross over the Great Lakes.
Title: Western Pennsylvania
Content:  Western Pennsylvania is a region in the U.S. state of Pennsylvania, covering the western third of the state. Pittsburgh is the region's principal city, with a metropolitan area population of about 2.4 million people, and serves as its economic and cultural center. Erie, Altoona, and Johnstown are its other metropolitan centers. As of the 2010 census, Western Pennsylvania's total population is nearly 4 million. Although the Commonwealth does not designate Western Pennsylvania as an official region, since colonial times it has retained a distinct identity not only because of its geographical distance from Philadelphia, the beginning of Pennsylvania settlement, but especially because of its topographical separation from the east by virtue of the Appalachian Mountains, which characterize much of the western region.The strong cultural identity of Western Pennsylvania is reinforced by the state supreme court holding sessions in Pittsburgh, in addition to Harrisburg and Philadelphia.
Title: Pennsylvania
Content:   Pennsylvania's diverse topography also produces a variety of climates, though the entire state experiences cold winters and humid summers. Straddling two major zones, the majority of the state, except for the southeastern corner, has a humid continental climate (Köppen climate classification Dfb). The southern portion of the state has a humid subtropical climate. The largest city, Philadelphia, has a humid subtropical climate (Köppen Cfa). Summers are generally hot and humid. Moving toward the mountainous interior of the state, the winter climate becomes colder, the number of cloudy days increases, and snowfall amounts are greater. Western areas of the state, particularly locations near Lake Erie, can receive over 100 in of snowfall annually, and the entire state receives plentiful precipitation throughout the year. The state may be subject to severe weather from spring through summer into autumn. Tornadoes occur annually in the state, sometimes in large numbers, such as 30 recorded tornadoes in 2011; generally speaking, these tornadoes do not cause significant damage.

The Pittsburgh suburbs, historically a Democratic stronghold, have swung more Republican since the turn of the millennium. Democratic political consultant James Carville once pejoratively described Pennsylvania as "Philadelphia in the east, Pittsburgh in the west and Alabama in the middle". Political analysts and editorials refer to central Pennsylvania as the "T" in statewide elections. The Three Valleys (Delaware, Lehigh, and Wyoming) and greater Pittsburgh generally vote for Democratic candidates, while the majority of the counties in the central part of the state vote Republican. As a result, maps showing the results of statewide elections invariably form a "T" shape.
Title: Outline of Pennsylvania
Content:  The following outline is provided as an overview of and topical guide to the United States Commonwealth of Pennsylvania: The Commonwealth of Pennsylvania is the fifth most populous of the 50 states of the United States of America. Pennsylvania lies west of the Delaware River in the Mid-Atlantic United States. King Charles II of England granted William Penn a charter for a Colony of Pennsylvania in 1681. Philadelphia, the capital of the colony, soon rose to become the most populous city of British America. As Britain attempted to tighten its grip on its American colonies, many prominent Pennsylvanians called for greater independence for British America. The upper and lower counties of Pennsylvania 
Title: Geology of Pennsylvania
Content:   The Geology of Pennsylvania consists of six distinct physiographic provinces, three of which are subdivided into different sections. Each province has its own economic advantages and geologic hazards and plays an important role in shaping everyday life in the state. They are: (listed from the southeast corner to the northwest corner) the Atlantic Coastal Plain Province, the Piedmont Province, the New England Province, the Ridge and Valley Province, the Appalachian Plateau Province, and the Central Lowlands Province. A majority of the rocks in Pennsylvania exposed at the surface are sedimentary and were deposited during the Paleozoic Era. Almost all of the metamorphic and igneous rocks are confined to the southeast portion of the state. A total
