Glaciers melting
2 million years ago Glaciers were meltng for the last time. As a result of this, the sea level began to rise forming ridges above water as what we know today as the Barrier Islands. -
Period: 199 to Nov 18, 600
Beginnig of Climate Warming
In this time span, due to gradual warmer temperatures and glaciers melting, the ocean levels have rose. This resulted in how North Carolina looks as it does today. We have pine, spruce and fir trees in the cooler ridged mountain areas. Oak and hickory trees were more abundant in the Piedmont region which is located right near the coastal line due to the rise in sea level. -

Barrier Islands
These islands are landforms off the coast and a type of dune system. They form when three conditions intersect with each other. There being a large supply of sand, seas constant rising and falling levels and waves/wind causing erosion. -

Appalachain Mountains
The Appalachians first formed around 480 million years ago during the Ordovician Period and once they reached elevations similar to those of the Alps and the Rocky Mountains before they began to erode. -

Valleys
Valleys form from the erosion of water from a river cutting down through a mountain thus forming a V shaped valley. Glaciers will form masive U shaped valleys, they are typically slow moving and they scar the mountains and rock due to erosion. The Grand Canyon is a perfect eample of a V shaped valley. -

River Basins in North Carolina
River basins are landscapes of water that flow across or under on its way to a river. River basins lead to the ocean so it is essential that you keep them healthy and clean.A water shead includes humans, plants, animals, and human urbanization such as roads and buildings. -

Fall Zone
A fall zone is a break between an upland region of relatively hard crystalline basement rock and a coastal plain of softer sedimentary rock. You can only recognize them when they are crossed by a river because it forms a water fall and they are hard to not notice. -

Soil
As the sea level decreased and the coastal plains were once again above water, the sea shells and rich ocean algae and sea weed that once layed on the bottom of the ocean floor now all of a sudden became rich agriculuture soil. It also formed a layer of lime stone all across the piedmont region snd coastal plain -

The beginning of the ice age
1.6 million years ago the first Ice age began causing glaciers and polar ice caps to reform due to freezing temperatures. This caused the sea level to drop and expose what we know now as the coastal plains. -

Erosion
The Sand Hills were a result of erosion. Streams eroded the piedmont region and Blue Ridge transporting sedimants to the coastal plains. There, the water poured into the sediments carrying heavier clay down stream and leaving behind sand that piled into dunes due to the wind. -
EarthQuake in South Carolina
Magnitude 7.3
Intensity X
Most damaging earthquake to occur in the Southeast United States and one of the largest historic shocks in Eastern North America. Resulted in 60 casualties and 5-6 million dollars in property damage.
