What term describes an area where a continent is being stretched?

• A. Rift Valley
• B. Rock
• C. Run-off
• D. Sanitation

Answer: (A)

Tensile forces at plate boundaries pull continents apart, causing the crust to crack along normal faults and drop down between them. The down-dropped block between these faults forms a Rift Valley, a landscape created by continental stretching. An example is the East African Rift, where such stretching has created long valleys and lakes. The other terms don’t describe a geographical area formed by stretching: rock is just material, run-off is water flow, and sanitation relates to hygiene and public health.
