The crust that is now the Appalachians began folding over 300 million years ago, when the North American and African continental plates collided. high temperature and high confining pressure. As mountains get pushed up by continents colliding, they get tall enough that glaciers start to form on top. Bottom line: mountains can get taller than Mount Everest in earth gravity, like the Appalachians probably didbut not much taller. If hearing that the available evidence suggests we werent quite Himalayan in scale here in New England makes you sad, heres some consolation.

Southern Appalachian waterfalls generally were formed by the action of water on alternating layers of soft and hard rock. A shift in plate tectonics meant and the ocean that was off the east coast of what would become North America, called the Iapetus Ocean, started to close. To the west the Great Valley, the Valley Ridges, and the Appalachian Plateau (including the Alleghenies) are characterized by the second type of rocks, sediments of Paleozoic age (i.e., about 252 to 541 million years old). Now, since our question asker was specifically interested in New Hampshire, we have to point out that the evidence suggests the highest points were probably just off the East Coast (the tallest of the Appalachian peaks likely crumbled into the Atlantic when Pangea split into separate continents) down off the Delmarva Peninsula. During the Pangaean era, you could walk straight from New York to Morocco, and from Florida to Sierra Leone. A mass of 1.5 kg of air at 120 kPa and 24C24 ^ { \circ } \mathrm { C }24C is contained in a gas-tight, frictionless pistoncylinder device. There, lobes of rock, soil, and debris choke the lower reaches of many small stream valleys. In the interior of continents the earth's crust is typically about 40km thick and the elevation is near sea level. It can help to think of mountains (and the earths crust) like icebergs floating on top of the ocean (the earths semi-plastic mantle). What is the origin of this name?

The landforms of Earth are generally divided into physiographic divisions, consisting of physiographic provinces, which in turn consist of physiographic sections,[1][2][3] though some others use different terminology, such as realms, regions and subregions. The geologic history of the area is complex but can be broken down into four major orogenies, or mountain building events. Today, the soil of the Appalachian Basin and the sand of the Outer Banks is full of the sediment produced as the Central Pangaean Mountains eroded away.
