Botanical beach:
Botanical Beach is a beautiful scene that displays various geological phenomenons, on the field trip we were able to see evidence of glacial movement and the different types of rocks, as well as how the ocean shaped the shoreline.
INgNeOUS rocks
These types of rocks are formed by hot magma that cools, where minerals form and become solid. These types of rocks are either brought by glaciers or formed nearby and moved. The rock in the photo was probably brought there by glaciers.
Sedimentary rocks
Sedimentary rocks are formed by tinier particles that come from igneous rocks that have been compacted and formed as new rock. The rock in the photo would have been brought by a glacier, seeing as the type of rocks wouldn't be naturally formed in botanical beach. The different layers show the changes over time and addition to the original rock make it interesting to look at and guess how long it would have took to create such a thing.
metamorphic rock
Are formed when heat, chemicals or pressure act on the other types of rocks, often creating some form of crystallization. The metamorphic rock in the photo would have been compressed together, forming one solid rocks instead of separate ones. The crystallization in between the two joining rocks prove that it is a metamorphic rock.
chemical weathering
Chemical weathering can take different forms and have different effects. The first photo shown would have been harder rock surrounding less dense rock that was washed away by rain, or other chemicals, exposing the dark rock to the surface eventually. The second photo to the right shows the salt from water corroding the rock and changing it by the salt staying around and eroding it.
physical weathering and erosion
Weathering is the breaking down of objects, in this case rocks, to create smaller pieces of the puzzle, altering the original form. The photo on the left shows how overtime rocks can be broken down by water, wind, and friction of the shore and the ocean. The photo on the right shows the erosion and changes in appearance that water can make over time to rocks, with pockets and dents being formed in the rock.
Sandstone and shale
Sandstone is created by sand and rocks being cemented together, creating a lighter rock that is pressured by the ocean and easily changed in shape. The sandstone in the photo on the left shows the water marks that have been left, creating discrepancies in the rock, as well as where the tide would normally be on the bottom.
Shale is a fragile rock made from mud or clay that is formed from sedimentary rocks over time, being easily chipped away. The shale in the photo is lodged in other rocks, showing how cool rocks can be joining together.

glacial movement and ocean forming the landscape
Glacial movement is one way that rocks are moved to places they normally wouldn't be, and the photo to the left depicts that. The metamorphic rock wouldn't have been formed on Botanical Beach, and probably had moved a long way with the glaciers before they melted or dropped them off. There are many rocks on this beach that would have been moved by glaciers.
The ocean shapes our shorelines. Depending on the tide the way the rocks and other elements end up over time is because of those forces, as well as other natural impacts such as wind. The photo on the right shows how the different types of rocks, water and green life come together to form an awesome example of how beautiful the world can be.
