A geologist is making observations from atop a small mountain. She sees two parallel faults: one directly to the east and one directly to the west. She concludes that these faults are caused by tension stretching the crust. From what type of land feature is the geologist making her observations?

plateau

anticline

syncline

fault-block mountain

This is really a science question but i could not find it

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
