Little Tammy is explaining his friends about the rock cycle and the NC History. They are very excited about leaning new things.

Today, I'm going to talk about the Rock Cycle.

The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.

Examples:

Metamorphic Rocks: Limestone, Marble

Igneous Rocks: Basalt, Granite

Sedimentary Rocks: Sandstone, Conglomerate

The Rock Cycle

Can you explain to us about the NC history?

Thank you Tammy

Now we all know about the rock cycle

Sure, Why not?

250 million years ago, Africa and North America

collided to form the supercontinent Pangaea

Over millions of years, the compression caused

folding of rock, creating the Appalachian

Mountains

The Appalachian Mountains

The fall line is a zone that forms the border

between the Coastal Plain and the Piedmont.

Many towns in NC, like Raleigh, grew on the

fall line to serve trade lines coming in from the

coast

TheFall Zone

200 million years ago, Africa and North

America began to split apart

The Atlantic Ocean formed.

Rivers carried sediment from the mountains,

which helped form the Coastal Plain

Shorelines
