Deforming the Earth's Crust Chapter 4 Lesson 4
Learning Target: LT#9 I can predict how the Earth’s surface will change at the different types of lithospheric plate boundaries.

DEFORMATION DEFORMATION IS WHEN THE SHAPE OF THE ROCK IS CHANGED DUE TO STRESS. COMPRESSION: A SQUEEZING STRESS (LIKE AT A CONVERGENT BOUNDARY) TENSION: A STRETCHING STRESS (LIKE AT A DIVERGENT BOUNDARY)

FOLDING FOLDING: BENDING DUE TO STRESS ANTICLINE: UPWARD FOLD (ARCH)
SYNCLINE: DOWNWARD FOLD (TROUGH) MONOCLINE: FOLD WITH HORIZONTAL ENDS

FAULTS FAULT: A BREAK IN ROCK WHERE MOVEMENT OCCURS.
NORMAL FAULT: WHEN ROCKS ARE PULLED APART (HANGING WALL DROPS) REVERSE FAULT: WHEN ROCKS ARE PUSHED TOGETHER (HANGING WALL RISES) STRIKE-SLIP FAULT: HORIZONTAL MOVEMENT (LIKE A TRANSFORM BOUNDARY)

MOUNTAIN BUILDING FOLDED MOUNTAINS: AT CONVERGENT BOUNDARIES WHERE PLATES COLLIDE. FAULT-BLOCK MOUNTAINS: WHERE NORMAL FAULTS OCCUR. VOLCANIC MOUNTAINS: MAGMA THAT RISES TO THE SURFACE AND ERUPTS.

UPLIFT AND SUBSIDENCE UPLIFT: THE RISING OF REGIONS OF THE CRUST TO HIGHER ELEVATIONS. SUBSIDENCE: THE SINKING OF REGIONS OF THE CRUST TO LOWER ELEVATIONS. (HOT ROCK COOLING)

EROSION LT#10 I can describe how moving water shapes the surface of the Earth by the process of erosion.

WEATHERING, EROSION, AND DEPOSITION
WEATHERING: PROCESS IN WHICH WATER, WIND, ICE, AND HEAT BREAK DOWN ROCK. AS WATER FLOWS OVER ROCK, IT CAN ERODE THE ROCK. EROSION: WIND, WATER, ICE, OR GRAVITY TRANSPORTS SOIL AND SEDIMENT FROM ONE LOCATION TO ANOTHER.

WEATHERING, EROSION, AND DEPOSITION
DEPOSITION: THE PROCESS IN WHICH MATERIAL IS LAID DOWN
