Question

Given below are pairs of statements. Select the statements which prove the spherical shape of the earth.

1. If there were no buildings in the way, we would be able to see another city that is hundreds of miles away.
2. The boat would stay in view no matter how far out to sea it went.
3. A ship slowly starts to disappear from view as it gets farther away.
4. If we were to place two identical sticks in the ground in two different places, the length of their shadows differs.
5. During a lunar eclipse, the sun projects Earth's shadow onto the moon and the shadow is round.

• 1, 4, 5

Answer 1

3, 4, 5

Explanation:

• Statement 3: This happens because of the curvature of the Earth. As a ship moves farther away, the bottom part of the ship disappears first, which is only possible if the Earth is spherical.
• Statement 4: This is evidence of the Earth’s curvature. In different locations on the Earth, the angle at which sunlight hits the surface is different, causing shadows to vary. This would not happen if the Earth were flat.
• Statement 5: The Earth's shadow on the moon is round during a lunar eclipse, which proves that the Earth is spherical.
