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 is earths position in June?
In June, Earth is tilted on its axis such that the Northern Hemisphere is tilted towards the Sun, resulting in the summer solstice around June 21. This position causes longer daylight hours and warmer temperatures in the Northern Hemisphere, while the Southern Hemisphere experiences shorter days and cooler temperatures, marking the beginning of winter there. The Earth's orbit around the Sun remains elliptical, but the axial tilt primarily influences the seasonal changes experienced in both hemispheres.
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 position will Sirius be in on June 21 2010?
Next to the sun
Describe how eratosthenes measure the size of Earth?
Eratosthenes measured the size of Earth by using the Sun's angles, as well as a bit of geometry.
Who reasoned that the sun must be curved?
Eratosthenes (275-c. 195 B.C)
What observations allowed Eratosthenes allowed him to understand the earth?
Eratosthenes observed that at noon during the summer solstice, the sun cast no shadow in Syene (modern Aswan, Egypt) while at the same time, shadows were cast in Alexandria. By measuring the angle of the shadow in Alexandria and knowing the distance between the two cities, he used basic geometry to calculate the circumference of the Earth. His observations of the sun's position and the varying shadows provided the foundation for estimating the Earth's size with remarkable accuracy for his time.
