Answer:
Three identifying properties that would help tell a geologist which depositional environment a sandstone was formed in is sorting, roundness, and composition. Sandstone that has formed in an Aeolian environment will have well sorted particles that are rounded. Sandstone that has formed in a beach/shoreline environment will also be very well sorted. Sandstone formed in rivers on land will be poorly sorted. The longer amount of time particles are transported the better sorted they will form. Rounded grains are more likely to have been transported by water or wind for a longer time such as in a sedimentary rock formed in an Aeolian environment by wind or one formed in a beach/shoreline environment by waves. Sandstone formed in an Aeolian environment will have a larger quantity of quartz as it is a more durable mineral than feldspar and ferromagnesian. Sandstone that has a significant amount of feldspar and ferromagnesium minerals is more likely to have gone through little chemical weathering and transport and was probably deposited close to the source area of the rock particles. We can also tell a lot by the kind of fossils that are fossilized in a sedimentary rock by analyzing what kind of organism or plant it is and if they were found on land or in water during that time period.
Answer:
The political stage of the United States is dominated by two political parties named democratic and republican party. Its been a long time since one of the party rule while others sit in opposition and the basic difference is seen in their ideological orientation.
