In deserts of southwestern North America developers often build houses in dry stream beds and build only minimal subsurface drai

nage systems to handle a flow of water comparable to the size of the dry stream channel. Is this a reasonable development model in the interest of public safety?
1. Yes, although flash floods an occur, using the channel size is a reasonable estimate of the maximum flood size.
2. Yes, any potential flooding catastriphe would be a 100 year flood event and would have adequate warning to evacuate people for safety, so the drainage system is adequate.
3. No, flash floods can produce high viscosity mudflows that would not be captured by the drainage system and could flow out over the valley, destroying everything in its path.
4. No, giant rock avalanches could come down the valley covering houses.

When an oceanic plate collides with a continental plate, the continental plate usually slides up and over the denser oceanic pla
KengaRu [80]
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.
