Question

The umbra of the Earth's shadow always points:

A.
Towards the Sun.

B.
Directly towards the Moon.

C.
Directly away from the Sun.

Answer 1

C.Directly away from the Sun.

Explanation:

The umbra of Earth’s shadow is about 1.4 million km (860,000 mi) long and points directly away from the sun. A giant screen placed in the shadow at the average distance of the moon would reveal a dark umbra about 9000 km (5700 mi) in diameter, and the faint outer edges of the penumbra would mark a circle about 16,000 km (10,000 mi) in diameter. For comparison, the moon’s diameter is only 3476 km (2160 mi). Consequently, when the moon’s orbit carries it through the umbra, it has plenty of room to become completely immersed in shadow.

Answer 2

C. Directly away from the sun

When you look at the sun shining in the Earth, the side it’s shining on is gonna have light, while the other is the shadow. No matter which way the sun shines, the darker side (shadow side) is never gonna be on the side towards the sun.
