Between 1978 and 2008, Oklahoma had just two earthquakes with a magnitude over 3.0. In 2014, thus far, there have been around 200 such earthquakes there, more even than the highly unstable state of California.
Instead of injecting waste water into formations, water recycling and purification plants need to become abundant, to minimize the amount of fluid to be disposed, as well as provide fresh water for crops & lakes.
Is having a beard a prerequisite of studying geology? Will growing a beard help me learn geology better? Plz halp
Some form of facial hair is required. It in know way helps you learn geology more easily. Women are proof enough of that, but it is mandatory for men. All geologist must be able to drink beer at a moments notice also.
Can someone who knows geology tell how geodes form?
A geode is formed when there is a cavity in a rock. The most common occurrence is in igneous rocks when a bubble of carbon dioxide & water vapor is trapped, an the molten lava cools and hardens, the gas disolves, and you have a hollow space. Another example takes place in sedimentary rocks, where a solid core of rock, where a portion begins to precipitate or dissolve out, leaving a void space. Or, you can have something organic, like a log, that is buried in sediments, and over time the log dissolves, leaving a void in the rock.
So in short, step one, you have a void in the rock. Step two, you have mineral rich water that seeps through the pore space of the outer rock, leaving a new layer of mineral deposits on the inside of the outer crust. Over the course of millions of years, different minerals layers are deposited in the hollow interior leading to crystals forming, and the different unique designs you find in each.
