I love rocks. And I’m talking about the fabulous large rock formations that are out in the wild. The rocks that built and shaped the amazing planet we live on.
So let’s talk a little about rocks…
A friendly reminder: all rocks should be left, as they were found, as they are part of that areas ecosystem and so others can experience them as well.
Did you know rocks are made up of different minerals, crystals, other rocks, shells, and even plants. Understanding what the rock is made of can help us learn about the history of the area!
Let’s look at the three types of rocks:
Igneous Rocks
– “fire-born,” are formed from the cooling & solidification of molten rock
– intrusive (plutonic) rocks are solidify within Earth, large in size, & most common are granite, diorite, and gabbro
– extrusive (volcanic) rocks are erupt onto the surface, smaller in size, & most common are basalt, andesite, dacite, and rhyolite
Sedimentary Rocks
– formed from deposits of pre-existing rocks or pieces of once-living organism & known for their distinctive layers
– clastic rocks are pieces of pre-existing rocks that are loosened by weathering, most common is sandstone
– biological rocks are when living organisms die, pile up, & are compressed/cemented together, most common is coal & limestone
– chemical rocks form when water tracking through rocks dissolves some of the minerals & then redeposits them elsewhere
Metamorphic Rocks
– formed when high temps & pressure alter the physical & chemical properties of the rock
– types include gneiss, quartzite, marble, schist, soapstone, and phyllite
– foliated rocks develop a sheet-like structure which reflects the direction the pressure happened
To be honest I just look at the rocks and take them all in.
