Gorges are narrow/skinny valleys between hills or mountains that often have a stream or river running through it. Waterfalls are rivers that stop and drop vertically into another body of water.
Hope this helped :)
A climate like a desert because, there is less water and it is too hot to live in.
The correct answer is B Subduction. Subduction is the process by which an oceanic plate gets dragged under another plate and is eventually destroyed in the mantle. Subduction occurs at convergent margins where two oceanic plates collide or an oceanic and Continental plate collide. Oceanic crust is made of mainly of silica and magnesium which is heavier or denser than continental crust which is composed mainly of silica and aluminium.
The subducting plate melts producing excess magma giving rise to volcanoes along these margins.
