the simplest and earliest method for determing the size of the earth uses

Answers

Answer 1
The answer is: comparing the Sun’s relative position at two different locations on the earth’s surface.

Explanation:

In the third century BCE , Eratosthenes, a Greek librarian in Alexandria , Egypt , determined the earth's circumference to be 40,250 to 45,900 kilometers (25,000 to 28,500 miles) by comparing the Sun's relative position at two different locations on the earth's surface.

Eratosthenes determined the earth's size by observing known phenomena and applying basic arithmetic and geometry to them. Here's how he did it. Eratosthenes' methods were simple but effective. All he needed to know was the distance between two locations and what percentage of a circle this distance constituted.

Answers

Answer: south and north poles

Explanation:

The diameter is different near the equator and in the poles because the earth is an oblate spheroid. The great circle has its largest circumference near the equator because its diameter there is larger than its diameter at either pole.

What happens at the equator?

The northern and southern hemispheres of the Earth are separated by the Equator, and each experiences varying levels of daylight at various times. The tilt of the Earth's axis and its orbit around the sun cause this, as well as weather, climate, and the seasons that humans experience.

The circumference of the Earth is 24,901.55 miles at the equator (40,075.16 km). 24,859.82 miles separate the North and South poles, which is a little less distance (40,008 km). At the poles, the diameter of the Earth is 7,899.80 miles (12,713.5 km), and at the equator, it is 7,926.28 miles (12,756.1 km).

It is much due to human activities that resources are getting depleted day by day.

We do not understand that if this continues, our future generation will not have anything left to use for themselves.

Hence all this leads to a negative impact on the environment and biological cycle as a whole.

Large scale fishing of fishes have decreased the overall number of fishes and pisci-culture has even been started where fish breeders use artificial means of breeding new fishes which cannot be healthy like the others.

Also, people have started to fell trees for firewood or for sandal wood and other aesthetic products.

However this has led to an imbalance in overall content of oxygen and carbon dioxide content in air. Many animals have become home-less.

Land is even getting harmed due to conversion of arable land into habitable land and large scale deforestation leading to land quality depletion for factories, housing, etc.

Explanation:

How do climate and vegetation affect life on Earth?

Answers

Plants provides oxygen, and plants need a comfortable climate to grow to their fullest potential. But because of the populations unsustainable practices (activities that cause pollution to the air, water and land), the climate has changed drastically. So drastic that the conditions are unsuitable for plant life. Without plants, the pace of climate change will only increase — as will desertification, soil erosion, flooding, and an increase of greenhouse gasses in the atmosphere.

Answer:

The Caspian Sea, located on Iran's northern border, surrounded by Azerbaijan, Kazakhstan, and Turkmenistan, and sharing a border with the south-west corner of Russian territory, is the epicenter of a collision of regional, national and business issues. These include questions among the littoral countries over demarcating the Sea, route diversification for oil pipelines, state interests, investor concern over political and ethnic stability, and the role of international agreements.

Economic interests: Russia wants to ensure that cash flows in the form of Western capital will continue from Central Asian and Siberian oil fields, and that cash flows are not be redirected out of Russia and into the Caspian region. Russia can compete on a level playing field with Kazakhstan and other Caspian oil investors with the proper Production Sharing Agreement (PSA) legislation in place.
