Answer 1

Answer:

Explanation:

• Earths shadow is the shadow that earth itself casts through its atmosphere and into outer space, toward the antisolar point.
• The umbra is the shadow's dark center portion, while the penumbra and the ant umbra are different types of half shadows.
• The umbra, penumbra and ant umbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object.
• Earth's rotation causes shadows to change because the sun's light shines on objects from different directions as earth rotates.
• The sun is rising in the east. the sun is beginning to set in the west. the sun is directly above you.
• Therefore option 1 that is only 1 and 2 are correct is correct answer.
