Eratosthenes used his knowledge of geometry, trigonometry, and astronomy to estimate Earth's circumference. By measuring the angle of the shadow cast by a vertical stick in two different locations and calculating the distance between them, he was able to make a remarkably accurate calculation.

What is Earths circumference measured between North and South poles?
The circumference of the Earth measured between the North and South poles is approximately 40,007.86 kilometers.
What is the circumference and diameter of Earth in miles?
The circumference of the earth in miles is about 24,901 miles. The diameter is about 7,926 miles.
What is a word that means science that records facts about the earths surface?
The science which records facts about the Earth's surface is called geology.
What is the science of studying the earths surface and its features called?
The science of studying Earth's surface and its features is called geology. Geologists study the composition, structure, and processes of the Earth's crust, as well as the history of the planet and its formation.
What is outgassing in earth science?
Outgassing in Earth science refers to the release of gases from the interior of the Earth, typically through volcanoes or vents. This process plays a role in the Earth's atmosphere composition and can contribute to climate change by releasing greenhouse gases like carbon dioxide and sulfur dioxide.
In ancient Greece who estimated the earths circumference?
Eratosthenes is credited with calclating the circumference of the Earth at the equivalent of 25,000 miles/40,000km in about 205 BCE.
Is it true or false that the Greek Eratosthenes is known for his calculation of the earths weight?
False. He is the first known person to calculate the circumference of the earth. Wikipedia has more information in their post on this interesting fellow. A link to the post is provided below.
Who discovered the earths curcumference?
The Greek mathematician and astronomer Eratosthenes is credited with calculating the Earth's circumference around 240 B.C. using the angle of the sun's rays at two different locations and the distance between those locations. This method provided a reasonably accurate estimate of the Earth's size.
What is the impact of Hellenistic culture on modern society?
From Hellenistic culture we get theories on astronomy, mathematics, and physics. Aristarchus's theories include, that the sun was 300 times larger than the earth, but he grossly underestimated it, and the earth and other planets revolve around the sun. Eratosthenes estimated earths circumference to be 28,000-29,000 miles long, close to the actual circumference. From Hellenistic culture we get the Pythagorean theorem and pi (the ratio of a circumference of a circle to its diameter) Archimedes (who also estimated pi) discovered the law of the lever. He invented a screw that lifts water from the ground and the pulley.
Is the greek eratosthenes known for his calculation of the earths weight?
False
How large is the Earths circumference?
Earth's Circumference is 24,901 miles (40,075 km)
What Greek astronomer used observations of the Sun's position at noon on the summer solstice at Alexandria and Syene to determine the circumference of the Earth?
n the 200s BC, Eratosthenes figured out a very clever method for measuring the size of the Earth. He heard about a well in Syene (in modern Egypt) where the sunshine reached the bottom only at noon in the summer solstice. So he knew exactly when the sun was directly overhead. Further north in Alexandria he put a stick straight up in the ground and measured the angle of its shadow at that precise moment as 7.2°. It meant that the distance from Syene to Alexandria was 7.2/360 of the Earth's circumference. Since he knew this distance, he could compute the circumference as 39250km, a diameter of about 12500km.n the 200s BC, Eratosthenes figured out a very clever method for measuring the size of the Earth.
