Pressure, lava, Ice, Flood

What Made NYC

By Louie

                                                              Pressure

First came pressure which started when North America crashed into Africa. Before pangea came the continents were separate but they had different shapes. Over 1000’s of years they crashed into and one another then they went on top of each other. That formed a vast mountain range that was as tall as the Alps.

Lava

After presser came lava and about 200 million years ago is when it started. Then extreme heat and pressure transform shale rock into schist. Schist is Earths crust. Then the Supercontinent of Pangea formed. Then North America and Africa start separating because the lava way erupting out of the, Earth’s crust, schist. When the lava erupted it covered a million square miles of land.

Ice

Third came ice which happened about 18,000 years ago. Then an ice Sheet covers New York region. The ice sheet shaped the hudson river. The ice was making the mountains like sand paper and the same thing was happening in the swiss Alps. The ice was covering 4x the height of the Empire State Building.

Flood

Finally came the flood. There was a land bridge that connected Staten Island to Brooklyn. That version of the hudson River did not have salt water in it. Then the Ice melted and the Hudson River overflowed and sunk the land bridge.
