Earthquakes are caused when plates shift. Hope that helps!
The answer is climate because the words growing season refers to the climate of the area
Metallic minerals become concentrated in liquid magma due to igneous, hydrothermal processes.
When magma forms first, it cools down and sink. The minerals concentrate at the top forming hydrothermal fluid.
If there are bodies of water and land to cultivate nearby then that is a good situation for agriculture to take place so that there is where to plant and also a source of water to keep the plants alive and growing. Where human beings find such a geographic situation, say like along the Nile River then a class of small farmers can develop and this is a social stratum.
