Summary of the 14 stations


Station 1

Coral base or colar reef can be found near the coast, in beaches or ocean floors

Station 2
Sandstone is light colored almost the same color as sand and it can be dark colored too, in some sides or parts. Friable means something that can be reduced to powder. Some environments where you would find large deposits of sand are beach, dessert and alluvial fans

Station 3
Differences between sandstone specimens are the color and the roundness or shape, and similarities can be the texture, and they are all fine grained. The type of cementing agent that is found in each of the sandstone speciments are iron oxide and calcite. The hardest sandstone type is silica

Station 4
We measured the different types of sand and the differences between color, size and shapes

Station 5
The sandstone specimens are cemented together with the same cementing agent because they share the same color and almost the same composition, sandstone might form on glacial, alluvial fans, deposits and passing streans

Station 6
Wavy parts of the rocks happened to be because of the environment that they were placed on, for example on beaches or oceans. Ripple marks are formed by water, the ridges are formed at right angles to the direction of motivation.

Station 7
Table about the sediments and sedimentary rocks

Station 8
Differences between coat and peat, the density of the coat is more than the density of the peat even though the peat is bigger than the coat. The peat is less dense than the coat, it is brown, (dark) with organic stuff on it. Coal is more dense than the peat it looks fragile and it has different sheets/layers. the major uses of coal is to produce heat in homes and factories or generators, cement and cases.

Station 9
Chert can be found in north america it is black-greyish rock with different fragments, it is formed by calcium-carbonate and silica. Jasper is found in north america and its red-orange rock with alot of fragments, formed by iron dioxide. Agate is found in north america, it is black, orange, gray fragmental with conchoidal pressure, its formed by silica. Rock gypsum can be found in shallow arms of the sea, it is white, clear rock luster in looks like its formed by sheets, its formed by sodium chloride and hydrous calcium sulfate.

Station 10
Datas about the tube and specimens on it.

Station 11
Some animals that live on beach tyepe environment are crabs, turtles, fish, etc. Biotubation means how people or animals affect the environment by leaving behind footprints, trails, burrows and feeding traces.

Station 12
The shell and the cast have the same shape, the cast has the same marks and lines but the consistence is different, the cast is softer than the shell. The methods of preservation are petrified, mold and cast, a fossil can be preserved by a thin carbon film, impressions and wood in petrified.

Station 13
the crinoids lfestyle and environment is almost as the fish environment, the move around to catch them food, they live in the bottom of the ocean and they have skeletons, their environment is the oceanic floor.

Station 14
how the shells and sediments can be compared in tables and datas. whats their environment.
