The geological phenomenon of tectonic activities created the rift valleys.
What are tectonic activities?
Major landforms are produced as a result of the underground motions of the Earth, according to the scientific hypothesis of plate tectonics. The idea, which became firmly established in the 1960s, revolutionised earth sciences by describing a wide range of phenomena, such as mountain-building events, volcanic eruptions, and earthquakes.
The widely recognized scientific hypothesis known as plate tectonics postulates that the Earth's lithosphere is made up of many sizable tectonic plates that have been steadily moving for around 3.4 billion years.
What are rift valleys?
A geologic rift results in the formation of rift valleys, which are linear lowlands positioned between numerous peaks or mountain ranges. Rifts are created when extensional tectonics causes the lithosphere to tear apart. After that, erosional pressures may deepen the linear depression even more.
