Rift valley is formed-

The correct answer is Between two faults.

Key Points

• A rift valley is a lowland region that forms where Earth's tectonic plates move apart, or rift.
• It is characterized by steep walls formed by the displacement of a block of the Earth's crust between two faults.
• Rift valleys can be found on both land and the ocean floor, for instance, the East African Rift.
• Such valleys are typically formed by the process of crustal extension, which can lead to significant geological activity such as earthquakes and volcanic eruptions.

Additional Information

• Tectonic Plates:
  • Large pieces of Earth's lithosphere that move over the asthenosphere.
  • Their interactions cause most of Earth's seismic and volcanic activity.
• Faults:
  • Fractures in Earth's crust where blocks of land have moved past each other.
  • They can cause significant geological formations and are often associated with earthquakes.
• Crustal Extension:
  • Occurs when tectonic plates move away from each other, thinning the Earth's crust.
  • Can result in the formation of rift valleys and other geological features.
• East African Rift:
  • A major rift valley that is an example of an active continental rift zone.
  • It stretches over several thousand kilometers from the Afar Triple Junction in the Horn of Africa to Mozambique.
