Question

1. what part of the sundial created a shadow?

a) a carved line
b) a gnomon
c) a digital screen
d) a candle

Explanation:

A sundial uses a gnomon (a raised part, like a rod or triangle) to cast a shadow that indicates time. A carved line is part of the dial for reading, a digital screen is not in traditional sundials, and a candle is unrelated to sundial shadow - casting.

Answer:

b) A gnomon
