2 to 4

An ___________ occurs when the moon's shadow hits Earth or Earth's shadow hits the moon.

Eclipse

What are the key differences between total and annular eclipses?

A total eclipse is when the near side of orbit appears bigger. An annular eclipse is when the far side of orbit appears smaller.

How doers an annular eclipse differ from a total eclipse?

An annular eclipse shows light, but a total eclipse is completely dark.

Explain the difference between a partial and total lunar eclipse?

During a total lunar eclipse, the moon and sun are on the exact opposite sides of the Earth, leaving the moon entirely in the Earth's shadow. During a partial lunar eclipse, only part of the moon is in the Earth's shadow.

What is the only lunar phase in which a lunar eclipse can occur?

Full moon.

The force of ___________ pulls the moon and Earth toward each other.

Gravity

A ________ eclipse occurs at a full moon when Earth is directly between the moon and the sun.

Lunar

A _________ tide occurs when the sun is at right angles to the line between Earth and the moon.

Neap

What is the only lunar phase in which a solar eclipse can occur?

New Moon

A person standing in the moon's _______________ would see a partial solar eclipse.

Penumbra

The moon's shadow consists of two parts; describe in detail what they are?

Penumbra is the moon's faint outer shadow and partial solar eclipses are visible from within the penumbral shadow. Umbra is the moon's dark inter shadow and total solar eclipses are visible from within the umbral shadow.

List and describe the three different kinds of lunar eclipses.

Penumbral, Partial, Total lunar eclipse. Penumbral lunar eclipse - the moon passes the earth's penumbra shadow. Partial lunar eclipse - part of the umbra. Total lunar eclipse - the entire moon covers umbra and penumbra.

The ____________ of the moon you see depend on how much of the sunlit side of the moon faces Earth.

A ________ eclipse occurs when the moon passes between Earth and the sun

Why isn't there a solar eclipse with every new moon phase?

The path of the Moon's shadow across the Earth's surface is called?

The path of totality

Why does the Moon appear to take on a colored hue during an eclipse?

The sunlight must press change through the Earth's atmosphere which filters and rockets light.

Explain differences between umbra and penumbra.

The umbra is the inner part of the shadow, where the moon blocks all the sun's light and total eclipses occur. The penumbra is the outer part of the shadow, in which the moon blocks only part of the sun's light and occurs in partial eclipses.

Differences in the moon's pull on different parts of Earth cause ___________.

Tides

A person standing in the moon's _____________ would see a total solar eclipse.

Umbra

What causes a lunar eclipse?

When the Earth is between the moon and sun. Earth blocks the sunlight.

What causes a solar eclipse?

When the moon passes between the Earth and Sun.
