Eratosthenes learned about the position of the sun on June 22 by noticing that in the city of Alexandria, a vertical stick didn't cast a shadow on that date. At the same time in Syene, a city to the south, a vertical stick did cast a shadow. By measuring the angle of the shadow at both locations, he was able to calculate the Earth's circumference.

How did Eratosthenes learn about the position of the sun?
Eratosthenes learned about the position of the sun by observing the angle of a shadow cast by a vertical stick in Alexandria at the same time a stick in Syene had no shadow. By measuring this angle and knowing the distance between the two cities, he was able to calculate the Earth's circumference.
Does Eratosthenes determine Earth's diameter?
Yes, Eratosthenes estimated the Earth's diameter using the angle of the sun's rays at two different locations on the same day. By measuring the difference in the angles, he was able to calculate the Earth's circumference and thus its diameter.
The sun's ray strike earth at the northernmost and southern most positions during?
The sun's rays strike the Earth at the northernmost position during the June solstice and at the southernmost position during the December solstice. These positions are known as the Tropic of Cancer (northernmost) and the Tropic of Capricorn (southernmost) respectively.
What are the 2 broken lines names on a map 1 lies north and 2 lies south?
The broken line lying to the north is likely the Tropic of Cancer, which marks the northernmost position of the sun on the June solstice. The broken line to the south is probably the Tropic of Capricorn, representing the southernmost position of the sun on the December solstice.
What beliefs about Earth and the heavens were proved by the discoveries of Aristarchus and Erastosthenes?
Aristarchus proposed the heliocentric model, suggesting that the Earth orbits the Sun, which challenged the prevailing geocentric view that the Earth was the center of the universe. Eratosthenes, through his measurements of shadows and the angle of the Sun's rays, calculated the Earth's circumference, providing evidence of its spherical shape. Together, their discoveries promoted a more accurate understanding of the Earth’s position in relation to the heavens and demonstrated that the Earth is a spherical body moving around the Sun.

Describe how eratosthenes measure the size of Earth?
