Rocks, Minerals, and Folks Presentation with geologist, Dr. Jane Nielson
We live on a rocky planet. Rocks form the Earth’s solid surface provide raw material for human industries, structural materials, gems, medicines, and even food additives. The conditions of local surface rocks define the stability of human building sites. This talk will introduce the major rock types and discuss the Earth processes that drive cycles of rock formation and transformation— including climatic influences such as the hydrologic processes that we observe in the Laguna de Santa Rosa. It also will explain where the rock types tend to be found, and how to make sure that we experience them in mostly positive ways. This is the first in a series of three talks Dr. Nielson will be presenting with the Laguna Foundation this spring. The next one will be "Inside the Earth" on March 29, and "From Earth to the Moon and Back Again" on April 26.
