Answers

Answer 1

What is geological time?

Geological time is a term to refer to the frame of reference used to represent the events of the history of the Earth and of life in chronological order. It establishes divisions and subdivisions of the rocks according to their relative age.

What is the Grand Canyon?

The Grand Canyon is a colorful and rugged gorge carved out by the Colorado River over millions of years in northern Arizona, United States.

The Canyon was created by the Colorado River, whose course undermined the land for millions of years. It is about 446 km long, has mountain ranges between 6 and 29 km wide and reaches depths of more than 1,600 m.

Additionally, nearly 2 billion years of Earth's history has been exposed as the Colorado River and its tributaries cut through layer after layer of sediment at the same time the Colorado Plateau was uplifted.

According to the above, it can be inferred that the Grand Canyon exposes a small portion of the earth's history because it exposes only about 1.7 to 2 billion years and the Earth is about 4.5 billion years old.

Answer: Loki the trickster

Explanation: in Norse mythology, earthquake is created because of Loki the Trickster. The cause of this is rooted in the Death of Baldur son of Odin. Baldur was the only son of Odin and Frigg Queen of Asgard. When God of mischief and strife- Loki, murdered God of beauty and light- Baldr, he was chained in a cave with a snake-mounted above his head dripping venom. Loki’s wife stood with a bowl to catch the poison, but whenever she emptied the bowl, the poison dripped on Loki’s face that forced him to shake his head away.

Answers

Global warming is the long-term heating of the Earth's climate system experienced since the pre-industrial era (between 1850 and 1900) as a result of human activity, especially the combustion of fossil fuels, which raises high-temperature greenhouse gas levels in the Earth's environment.

What is a real-world example of global warming?

The rate at which sea levels are rising globally is increasing. This is due to both glacier melting and ocean thermal expansion as a result of increased air heat generated by emissions. Global warming is exemplified by widespread reductions in the extent of snow and ice.

Thus Option C is not a manmade cause of global warming.

Explain how the use of pesticide and chemical fertilizers have lead to reduce in its soil fertility and polluted water, river and stream

Answers

Many transformation products (TPs) from various pesticides have been identified. Few pesticide TPs have been studied in soil, indicating a pressing need for greater research in this area. Pesticides and their TPs are retained by soils to varying degrees depending on soil and pesticide interactions.

Pesticides were found in over 90% of water and fish samples from all streams. Pesticides were identified in 99 percent of urban streams and in all major rivers with agricultural and urban land use effects. The USGS reported that pesticide concentrations in urban streams often exceeded aquatic life protection requirements (U.S. Geological Survey, 1999).

Pesticides are ubiquitous pollutants in urban soil, air, water, and non-target creatures. Once there, they can harm non-target plants, fish, birds, and other species, as well as vital soil bacteria and insects. Toxic to fish, chlorpyrifos has caused fish kills in waterways near treated farms or structures. Aside from acute toxicity, several herbicides have sublethal effects on fish, reducing their chances of survival and endangering the population. Pesticide poisoning of dolphins has been reported globally.

A fertiliser, pesticide, industrial and domestic wastewater damage the Ganges river basin. Pesticides endanger not only fish but also other marine and freshwater animals. DDT and PCB exposure has been demonstrated to harm reproductive and immune functioning in confined and wild aquatic mammals. Herbicide contamination of water could have disastrous impacts on aquatic creatures, as herbicides are designed to harm vegetation. It can also kill birds by ruining their habitat.

Avitrol, a typical pigeon bait, can be eaten by non-target grain-eating birds. 2,4-D lowered the success of chicken egg hatching and caused feminisation or sterility in pheasant chicks. The use of OCs in tropical areas may expose both resident and migratory birds. OC pesticides and PCBs discovered in avian livers and eggs. OCs have been found in humans and wildlife from India (Senthilkumar et al., 2000). South India is home to the flying fox, short-nosed fruit bat, and Indian pipistrelle bat.
