| Much of the island is an ancient limestone seabed that has been upthrusted by tectonic forces. |
|
| One or both walls may be vertical, created by tectonic forces, as in the Annapolis Valley in Nova Scotia. |
|
| And New Jersey is particularly vulnerable because of tectonic forces and changes in ocean currents. |
|
| Powerful tectonic forces that over millions of years have created these features still occasionally cause earthquakes in Puerto Rico. |
|
| It and several neighbouring faults are related to extensional tectonic forces associated with the opening of the Tyrrhenian Basin to the west. |
|
| The result is that, based on the amount of water on earth, and observed tectonic forces, there was the potential to quickly raise mountains. |
|
| All of these tectonic forces have created volcanic regions in British Columbia that host a large variety of volcanoes. |
|
| Much of the rocky coastline in Atlantic Canada has been created by glacial activity and tectonic forces. |
|
| During this period tectonic forces slowly ripped apart the North American continent to form the Midcontinental Rift. |
|
| Enormous tectonic forces over geological time allowed the rock to move and fold slowly, like a thick fluid. |
|
| Any change in the original form or volume of rock masses produced by tectonic forces. |
|
| Agents of formation: large-scale tectonic forces, collision of plates, volcanism, folding. |
|
| The tectonic forces generated by this collision unleashed volcanic eruptions and earthquakes, which raised the Andes to over 1,500 meters in some places during a period of over 28 million years. |
|
| On the southern side of the alpine divide, tectonic forces and glacial erosion have resulted in a collection of spectacular peaks and a valley system which supports the two longest glaciers in western Eurasia. |
|
| Tells about the geography of the Sierra Madre mountains, and the tectonic forces which shaped California, as well as about gold mining in the Sierra Madres. |
|
| Imagine two points on the surface of the earth being separated over time as the crust is pulled apart by tectonic forces we can only begin to imagine. |
|
| At the plate edges where there is contact between adjoining plates, boundary tectonic forces operate on the rocks, causing physical and chemical changes in them. |
|
| Its expression is epitomized by the surface of objects such as the Moon and the planet Mercury, where the near absence of endogenic tectonic forces has left impact effects most intact. |
|
| In antecedent drainage, a river's vertical incision ability matches that of land uplift due to tectonic forces. |
|
| Area 2: The primary reservoirs are fractured shales caused by volume reduction as water was expelled from clays by tectonic forces related to the Cordilleran development. |
|
|
|
| It goes on and on, like a landscape sheered by tectonic forces. |
|
| The title is a geological term coined by geologists after the 1906 San Francisco earthquake which describes opposing tectonic forces moving in opposite direction along each side of a faultline. |
|
| Together these three tectonic forces are slowly developing into a new subduction system in the eastern Atlantic Basin. |
|
| Almost all of the Earth's islands are natural and have been formed by tectonic forces or volcanic eruptions. |
|
| Ophiolites are rare sequences of rocks formed when tectonic forces pushed upward a section of the Earth's upper mantle, oceanic crust and overlying sediments. |
|
| Differences in the height of mountain ranges are not only being the result tectonic forces, such as rock uplift, but also local climate variations. |
|
| Shaped by global plate tectonic forces that have created the East African Rift, East Africa is the site of Mount Kilimanjaro and Mount Kenya, the two tallest peaks in Africa. |
