Geography: Streams And Flooding

Original post by @moabdul123

Water is the most important factor sculpturing the earth's surface. Mountains rose by the activities of plate tectonics and volcanism, but are molded primarily by water. Streams valleys, level plains, move enormous weight of sediment from place to place. Floods are presumably the most widely experienced catastrophic geologic hazards. On the average, in the United States alone, floods annually take over eighty-five lives and cause well over $1 billion in property damage. Most of these floods do not make national headlines, but they are no less devastating to those affected by them...

Geology: Early evolution of the Earth - The origin of the planet Earth

Original post by @geoestacion

Recent earthquakes caused by displacements of the earth's crust, together with lava from the eruption of active volcanoes, represent only the latest in a long series of events through which our planet has reached its present form and structure. The geological processes that occur within the Earth can be better understood when observed in the context of much earlier events in the history of the Earth...

During modern times the subject was taken to the silver screen and TV screens and there were a lot of movies filmed with the theme about King Arthur some were bad some were good but this is a topic for another post.

History: Homo explorans – Voyagers Who Would Link the World

Original post by @ravenruis

What drove people in the fifteenth century to look to expanding from their known boundaries into the unknown? Three countries sponsored major explorations – Spain, Portugal and England – each with different priorities. Several leading factors which helped towards the general motivation by Western countries like Spain and Portugal to want to voyage, explore and discover new lands, new trading routes and new sources of wealth. One was the outbreak of hostilities between the Ottoman and Byzantine empires and the Muslim push into parts of India, which meant great difficulties in trading for the Iberians. Crusading had not been successful either, from a Western point of view, and the Holy Lan...
