Geologist believe that The crystals inside a geode probably form when...
A: Lava suddenly cools on earth’s surface
B: Minerals dissolved in a solution evaporate
C: Minerals dissolved in a solution crystallize
D: magma cools slowly inside Earth
Ok so I’m Almost positive that it’s C but I really want to make sure
I agree.

Ty Ms Sue!!!!
You are welcome.
To determine the correct answer, we can analyze each option:
A: Lava suddenly cools on Earth's surface - This option refers to the formation of igneous rocks, not geodes. Geodes are formed through a different process.
B: Minerals dissolved in a solution evaporate - This option is not correct. When minerals dissolve in a solution and evaporate, they typically form sedimentary rocks, not geodes.
D: Magma cools slowly inside Earth - This option also does not describe the formation of geodes. Magma cooling slowly inside the Earth results in the formation of intrusive igneous rocks like granite, not geodes.
Now let's consider option C: Minerals dissolved in a solution crystallize - Geologists believe that geodes form when minerals dissolved in a solution begin to crystallize. Over time, as the solution evaporates or cools, the minerals solidify and form the colorful crystals found inside geodes.
Therefore, the correct answer is indeed option C: Minerals dissolved in a solution crystallize. Geodes form through the crystallization of minerals dissolved in a solution.
