Well-rounded and Well-sorted sand grains indicate that sedimenta)Came ...
Explanation:
- Well-rounded and well-sorted sand grains are indicative of sediment that has undergone transportation and sorting processes.
- When sediments are transported over long distances, they are subjected to various erosional forces such as water currents, wind, and glaciers. These forces act to break down the sediments into smaller fragments and round them off.
- Additionally, during transportation, sediments are sorted based on their size and weight. Heavier particles settle out first, while lighter particles are carried further. This sorting process leads to sediments being well-sorted, with grains of similar sizes grouped together.
- Therefore, the presence of well-rounded and well-sorted sand grains suggests that the sediment has traveled from a distant source area.
- Option C - Traveled from a distant source area - is the correct answer because it accurately explains the characteristics of well-rounded and well-sorted sand grains.
- The other options can be eliminated because:
- Option A - Came from a nearby water source - does not account for the rounding and sorting processes that occur during long-distance transport.
- Option B - Was deposited at the location where it was found - does not explain the origin and characteristics of the sediment grains.
- Option D - Have not been influenced by weathering - does not address the processes of transportation and sorting that result in well-rounded and well-sorted grains.
- Therefore, the correct answer is option C.

Milankovitch proposed in the early twentieth century that the ice ages were caused by variations in the Earth’s orbit around the Sun. For some time, this theory was considered untestable, largely because there was no sufficiently precise chronology of the ice ages with which the orbital variations could be matched. To establish such a chronology, it is necessary to determine the relative amounts of land ice that existed at various times in the Earth’s past. A recent discovery makes such a determination possible: relative land-ice volume for a given period can be deduced from the ratio of two oxygen isotopes, 16 and 18, found in ocean sediments. Almost all the oxygen in water is oxygen 16, but a few molecules out of every thousand incorporate the heavier isotope 18.When an ice age begins, the continental ice sheets grow, steadily reducing the amount of water evaporated from the ocean that will eventually return to it. Because heavier isotopes tend to be left behind when water evaporates from the ocean surfaces, the remaining ocean water becomes progressively enriched in oxygen 18. The degree of enrichment can be determined by analyzing ocean sediments of the period, because these sediments are composed of calcium carbonate shells of marine organisms, shells that were constructed with oxygen atoms drawn from the surrounding ocean. The higher the ratio of oxygen 18 to oxygen 16 in a sedimentary specimen, the more land ice there was when the sediment was laid down.According to the passage, which of the following is true of the ratios of oxygen isotopes in ocean sediments?

Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over millions of years, these dead creatures form large deposits under the sea-bed; and ocean currents cover them with a blanket of sand and silt. As this mineral hardens, it becomes sedimentary rock and effectively shuts out the oxygen, so preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rock become thicker and heavier. Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.Q.Sedimentary rock leads to the formation of oil deposits because
