Solar Eclipses FDuring a new moon, most of the time the moon is a little above or below the sun in the sky. FA solar eclipse occurs when the moon passes between Earth and the sun, blocking the sunlight from reaching Earth. FIt is really a new moon that blocks your view of the sun.

Solar Eclipses

Total Solar Eclipses FUmbra - the darkest pat of the moon’s shadow that is cone-shaped. The point of the cone can reach a small part of Earth’s surface.

Partial Solar Eclipses FPenumbra - larger part of the shadow which is more visible on Earth. During a partial eclipse, part of the sun is visible. FIt is not safe to look at a partial eclipse.

Lunar Eclipses FA lunar eclipse occurs at a full moon when Earth is between the moon and the sun. Earth blocks sunlight from reaching the moon.

Total Lunar Eclipse FWhen the moon is in Earth’s umbra, you see a total lunar eclipse. You are more likely to see a total lunar eclipse than a total solar eclipse.

Partial Lunar Eclipses FOccurs when the moon passes partly into the umbra of Earth’s shadow. The edge of the shadow appears blurry and you can watch it pass across the moon for up to two or three hours.

Tides

Spring Tides When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Neap Tides During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are especially weak tides.
