In these geology activities your will be creating three molecules that are the building blocks of everything on Earth. You will be creating a water molecule, salt molecule, and a carbon dioxide. Silica is the most abundant mineral and it forms its crystal structure as a tetrahedron shown in the upper right-hand corner of the picture.
Water molecule -
Halite - Salt
Water is a universal solvent. It dissolves most materials found on Earth including rocks exposed on its surface due to erosion. Oil is an example of molecules that are repelled by water and do not dissolve in it.
Halite is common mineral that we know as salt. We use it to salt our food and it is the same salt found in the oceans. chemists call the mineral sodium chloride.
Carbon dioxide When we breathe in air it contains a mixture of gases including oxygen. When we exhale the air out of our lungs the main gas is carbon dixoide. Carbon dioxide in the air is used by plants for photosynthesis. A by-product of photosynthesis is the oxygen we breathe.
The silica tetrahedron has a negative charge so it bonds with many compounds by sharing oxygen atoms to form 95% of the minerals found on the Earth's surface that is why it was included in these geology activities.
