Now make a hole in the stack of pancakes by puncturing all but the top pancake layer with a straw. do not punch through the top pancake. remove the straw. then place the vanilla-frosting nozzle into the hole and insert a stream of frosting. what kind of geologic formation does this represent? explain.

This is a d/yke

Explanation:

The description of events in the problem is similar to that of an igneous intrusion through a sedimentary rock layers.

A d/yke is an igneous intrusion that cross cut a rock sequence vertically. The orientation of d/yke is usually against the bedding plane of the rock it cuts through. D/ykes are usually younger than the rocks they cut through.

The hole through the layers can be pictured as a weakness plane which can form as a result of fractures in the rock. The fractures allow for intruding magma to pass and move through. When the magma cools and solidifies within the fractures, it results in a d/yke.

D/ykes are usually of great economic importance.

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.
