Study Notes
Solar Eclipse
- A solar eclipse occurs when the Moon is positioned between the Sun and the Earth.
- The Moon, being made of rock, functions as an opaque object that obstructs light rays from the Sun.
- The Moon's shadow is cast onto the Earth during a solar eclipse.
- Observers within the central part of the Moon's shadow experience a total solar eclipse, where all direct sunlight is blocked.
- In areas outside the central shadow, a partial solar eclipse is visible where some light from the Sun still reaches the Earth.
Lunar Eclipse
- A lunar eclipse happens when the Earth is positioned between the Sun and the Moon.
- The Earth is an opaque object that blocks light from the Sun.
- The shadow of the Earth is cast on the moon.
- Solar and lunar eclipses do not occur every month because the Moon's orbit is slightly tilted relative to the Earth's orbit around the Sun.
- Eclipses can only occur when the Sun, Earth, and Moon align in a straight line.
- The Moon takes 27 days to orbit Earth
Shadows Explained
- An opaque object does not allow light to pass through it.
- Light travels in straight lines called rays.
- Shadows form when opaque objects block light from a light source.
- The area around a shadow appears brighter because it receives direct sunlight.
- When a shadow passes over a specific point, it appears darker, and it becomes brighter again once the shadow has passed.
- Never look directly at the Sun, even during an eclipse because it can cause permanent damage to your eyes.
