​Lesson 4.2.2: Plate Movements and Landforms

Multiple Choice

The Stress Force that pulls on the crust and thins the rock in the middle is

• Shearing

• Compression

• Tension

• Uplifting

Multiple Choice

The Stress Force that squeezes a rock until it folds or breaks is

• Shearing

• Compression

• Tension

• Uplifting

Multiple Choice

A fault in which the rocks on either side of the fault move sideways past each other is a __________

• Slip-Strike Fault

• Normal Fault

• Hanging Fault

• Reverse Fault

​How Does Plate Movement Create New Landforms

• Changes in the crust occur extremely slowly and are not easy to observe

• Over millions of years, the forces of plate movement can change a flat plain into different features

  • anticlines

  • synclines

  • folded mountains

  • fault-block mountains

  • plateaus

​Folding of the Earth's Crust

• Folds: bends in rock that form when compression shortens and thickens Earth's Crust

  • When the crusts fold, rocks bend without breaking

  • a fold can vary in width

8th Grade Science Ohio | Lesson 4.2.2

​Anticlines and Synclines

• Anticline: an upward bend in a rock

• Syncline: A downward bend in a rock

• Both Form in areas of compression in the crust

  • anticlines and synclines form when rocks fold over from compression

8th Grade Science Ohio | Lesson 4.2.2

​Stretching the Earth's Crust

• Tension can stretch the Crust and leave Valleys surrounded by high elevations

  • Fault-Block Mountains: Mountains f​ormed by tension

8th Grade Science Ohio | Lesson 4.2.2

​Uplifting the Earth's Crust

• Plateaus: a large area of flat land elevated high above sea level

  • has many different flat layers

  • Occur when forces in the crust push up large flat pieces of Rock​
