- #7 Earth’s Layers - (4:41) The Earth is made of three rock layers. The outermost layer is called the crust. The mantle is the thickest layer. The core is the innermost layer. The earth is broken into pieces called “plates” that push together , pull apart, and slide past each other.\n\n
- #8 The crust is mostly rock approx. 25 miles thick. Under the ocean it’s 3-6 miles thick. No one has yet drilled to the bottom of the crust.\nBecause gravity pulls things to the center of the earth and the increased pressure makes the center of the earth solid.\nThe mantle is very hot. Scientist think the top and bottom parts are rigid rock but are so hot they flow like thick syrup. The mantle is 1,789 miles thick.\n\n

- #11 Plate Tectonics - 2 minutes\n\n
- #12 Our crust rest on a hot mushy layer of rock called the mantle.\nThe liquid in the mantle moves around causing the crust to break and slide\nThe crust is made of of many different pieces called plates - there are many different plates. Geologists think 250 million years ago the earth was made up of a supercontinent called Pangea. The study of the plates is called “Plate Tectonics”\n

- #15 Folding - 1 minutes “How does land build up?”\nLand builds up when the plates push against each other to bend and rise\n\n
- #16 When plates push up against each other it creates pressure causing the land to fold and buckle. The surface begins to rise creating a mountain.\n
- #17 When plates push up against each other it creates pressure causing the land to fold and buckle. The surface begins to rise creating a mountain.\n
- #18 Volcanoes - 1 minutes “Other forces that cause the earth \nAs the earth’s crustal plates push against each other, the friction from the pressure can be so great it heats up the land creating magma. If the magma reaches the surface of the earth and breaks through, it creates a volcano. When the hot magma reaches the surface of the earth we call it lava.\nAn erupting volcano can form more land. Over millions of years, the land built by lava builds creating new land masses.\n

- #22 Earthquakes - 1 minutes “Sudden changes in the shape of the land”\nAs the plates move, parts of the land begins to bend. If the force becomes too great the land can slip or break. This break in the land is called a “fault” and the shaking of the land is called an earthquake.\nIf the land breaks and is pushed upward often enough it can create enormous mountain ranges.\n
- #23 As the plates move, parts of the land begins to bend. If the force becomes too great the land can slip or break. This break in the land is called a “fault” and the shaking of the land is called an earthquake.\nFamous earthquakes: 2011 Sendai, Japan, 2010 Haiti, 2005 Kashmir, Pakistan, 2004 Sumatra, Indonesia, 2003 Bam Iran, 1995 Kobe, Japan, 2001 Olympia, Washington\nIf the land breaks and is pushed upward often enough it can create enormous mountain ranges.\n
