As a result of which the <u>Pacific plate has got subducted</u> and <u>rate of subduction is very intense and fast</u> here because this lies in the region, commonly known as the "ring of fire".

Answer: The two geographic obstacles that stood in the way of the construction of the Panama Canal was that Panama was very mountainous, and there were a lot of mud slides.

Engineers had to build a dam, design and build locks, and remove huge amounts of earth and rock in order to overcome the geographical obstacles.
