Severely deformed sedimentary rock layers exposed in a roadcut of the Antelope Valley Freeway (Interstate Highway 19) within the San Andreas Fault zone near Palmdale, California. The sedimentary rocks were deposited in late Miocene streams & ponds. This folding and faulting occurs within the San Andreas Fault zone.

crownedrose: It really doesn’t get any better when you can just look at the beautiful deformations in geology. The photo above shows what is called ductile deformation, which is basically a gradual change where the rocks are morphing, folding, etc. This is all due to stress when the rocks have breached their elastic limit, and this now means it will be a permanent change for the rock.

Types of folds w/Photos. Ge-ology IN. Monocline: local warping in horizontal strata. Rock beds lying at two levels separated by steep inclined Iimbs. It is formed by vertical movement & generally found below a monocline, a step-like fold in rock strata consisting of a zone of steeper dip w/in an otherwise horizontal or gently-dipping sequence

A monocline is a step-like fold in rock strata consisting of a zone of steeper dip within an otherwise horizontal or gently-dipping sequence.

Here’s an easy science experiment you and your kids can do at home. The best part? There’s no messy clean-up afterwards. Simply fill a jar with tap water and drop in 4 drops of your favourite food colouring. Add 1/4 cup of vinegar, 3 tsps. ARM & HAMMER™ Baking Soda, and a small handful of buttons (HINT: Rice and pasta also work). Then sit back and watch them rise and fall.

Taking a shortcut to the sea! Canada's Horton River ends in a sprawling delta along the coast of a bay, but it once had a more meandering course, as seen in abandoned channels in this image taken by NASA's Earth Observatory-1 satellite on July 31, 2012.

Horton River Delta, Arctic Canada: Acquired July this image shows a delta where the Horton River long ago abandoned old river channels to take a shortcut to the sea.
