False. A rift valley forms when continental plates diverge or pull apart. When two continental plates collide the result is a mountain range.

True, and if the plates are moving apart there are generally volcanoes involved. A rift can also develop when two plates are moving in different directions.
LOL
No, the Great Rift Valley is not made up of a series of geological folds. It is a geographical trench system caused by the separation of tectonic plates in East Africa, forming a distinct depression in the Earth's surface. The rift valley is characterized by steep cliffs and escarpments rather than folds.
True
Convection current occurs due to the difference in densities
False. A strike-slip fault forms at a transform boundary where two tectonic plates slide past each other horizontally. A convergent boundary is formed when two plates collide and one plate is forced beneath the other in a subduction zone.
Terrane accretion typically occurs along a convergent boundary where two tectonic plates collide, rather than along a divergent boundary where they move apart. This process involves the collision and subsequent attachment of different crustal blocks or terranes to a continental margin or another terrane.
