Characterization of Sedimentary Basins-Trinidad’s Southern Basin Trinidad’s southern Basin is a topographically low area between the Central Range Uplift and the southern Range Uplift. It forms an eastern part of the eastern Venezuelan Basin‚ which is positioned east of Venezuela and the Orinoco Delta. The basin is structurally deformed as a result of compressional tectonics. The tectonics are attributed to a triple boundary created from the interplay of the southern American‚ Caribbean and Atlantic

Egypt is a country‚ almost completely made of sand. It is made up of two parts of the Saharan desert. However‚ there are two natural landscape feature that does provide haven from the dry desert land‚ the Nile River and the Nile Delta. No one knows specifically how the river formed but there are theories. One theory is that the Nile river is a result of According to Britannica Encyclopedia‚ the Nile river moves northward toward the Mediterranean sea‚ cutting right through the deserts of Egypt.

“The Gift of the Nile”. Before the Aswan Great Dam was built‚ the Nile was a source of soil and is still a source of water. When the Nile flooded‚ they got silt‚ a soil that let them grow a surplus of food. The Nile’s source of water brought population. The Nile could be used as a source of ducks and fish for food. The Nile gave them silt which was used to farm‚ it was great soil. The Nile was used to grow papyrus which was used as paper. The Nile could be used as a highway‚ so everyone lived

Firstly‚ the Nile River is located in Egypt. Egypt is divided into “Upper Egypt” and “Lower Egypt”. The Nile delta region (a marshy area of land that deposits silt at the mouth of the river) begins in upper Egypt and the Nile delta region extended 100 miles into the Mediterranean Sea from lower Egypt. The nile river flooded yearly‚ and left behind silt (mud/soil) and water. This was excellent for farming and allowed plants to thrive. As well as yearly flooding‚ irrigation ditches were used to help water

Sedimentator Lab Introduction: in this lab we will be working with a sedimentator to observe and classify sediments. A sediment is naturally-occurring material that is broken down by processes of weathering and erosion‚ and is subsequently transported by the action of fluids such as wind‚ water‚ or ice. Side One Purpose: to observe and classify sediments Part I 1. Gently shake the sedimentator to loosen the sediments and lay the sedimentator on its side 2. Observe the water
