guides that are well versed with knowledge about the Caroni Swamp so that they may educate visitors of the beauty and benefits of the swamp. The Caroni Swamp is useful to the people of Trinidad and Tobago since it protects the coast from storms, sediment filtration for near shore ecosystems and carbon sequestration. The Caroni Swamp is “critically important for conservation and the delivery of goods and services to the people…

dynamic shock process, and have been found in sediments of the K-T boundary, and other impact craters (Korberl et al (1997)). Therefore nanodiamonds in the YDB must result from ET sediments and shock processes, both of which can be explained by an ET impact (Kennett et al (2009)). Firestone et al., 2009, also suggests formation through wildfires, that were ignited through the impact (see below) These nanodiamonds have been found to peak in YDB sediments ~10 to 3700 ppb (REWU) (Firestone et al.,…

While changing land uses, sediments, sand and mad also runoff into the ocean and fall to the ocean floor. Some of the sediment covers the coral, which can damage the coral and cover the sunlight from getting to the coral; hence, restricting the processes of photosynthesis, which hinders growth. Actions that may be considered…

The California Gold Rush began in 1848 when James W. Marshall struck gold at Sutter’s Mill in Coloma, Ca. Thousands of people traveled to California by sea or by land to end their financial hardship. The discovery of gold in California spread like wild fire, at least once the message reached populated cities because there were no cell phones and social media. Once the news of gold was discovered and spread throughout the world there was an increase of population in San Francisco. The city of San…

Paleoclimatic Proxy records to reconstruct variability and climate patterns at the 1000 year scale. Some climate patterns have been observed in the paleo record that are not necessarily operating today. Cores from ice,coral reefs, ocean and lake sediments can provide a lot of information such as temperature, precipitation, chemical composition of air or water and etc. 10,000…

Sediment can clog water pathways, reducing the useful life of reservoirs and increasing dredging costs. “By raising streambeds and burying streamside wetlands, sediment increases the probability and severity of floods.” (Aillery et al.) Vital crop nutrients like nitrogen and phosphorus that are applied to fields each year in large volumes…

(in the question booklet) demonstrated a simplified stratigraphic profile. This shows the gravel rich sediments have increased in site 1 and 3 and a small amount of sediment in 2 and 4, meaning that erosion has increased from the glacier and river transport leading to a gravel rich sediment. Furthermore, there was reduced land coverage by birch/willow scrub cover from the smaller organic sediment…

of Earth to be 4,004 B.C. (Ticotsky, 2006). A couple of decades later, Nicolas Steno formulated the idea that is now known as “original horizontality” in which layers of sediment are originally deposited horizontally and therefore, younger sediment will be deposited atop older sediment. Nicolas Steno inferred that where sediment is not horizontal, a force must have tilted the deposition. Nicolas Steno was an early discoverer…

Coyne gives a comprehensive definition of evolution that explains the theory of evolution and the role that natural selection plays in the evolutionary process. He states that: Life on earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule- that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) evolutionary changes is natural selection (Coyne, p.3)…

How might conditions for successful fossilization differ between mammals and plants? How might a fossil be formed? What is the difference between mammals and plants being fossilized? What might happen to the fossil? Many things need to happen when mammals and plants fossilize. They cannot be disturbed, it cannot be brought to the surface until completely fossilized, and it depends on where they died. These things are very important when a mammal or plant are being fossilized. The organism…
