What's the difference between a normal and reverse fault?

Answer (Click to Show Hidden Text)

Normal fault sees the hanging wall move down relative to footwall and is formed by tensional stress, but reverse fault is hanging wall moving up, and is formed by compressional

FUN and FDR- footwall up is normal, footwall down is reverse

Your turn!

Alright...

1. What is a recumbent fold?
2. What is a slickenline and how is it formed?
3. How can you tell if a fold is overturned on a geologic map?
4. Describe how magma forms at subduction zones.

1. a fold with a horizontal axial plane, i.e. turned on its side
2. idk, something to do with folds
3. the bedding around it has their strikes and dips represented by the overturned bedding symbol
4. flux melting: addition of water from the ocean lowers the rock's melting point, allowing it to melt as it subducts into the mantle

Answer for 4 (Click to Show Hidden Text)

The subducting plate melts and upwells through the crust, which can often produce volcanoes.
