Our Earth and Its Moon

The Earth

• The earth is the only planet suitable for life.• God positioned Earth at just the right distance

from the sun so that all living things could tolerate the temperatures.

• The atmosphere is mostly nitrogen with 20% oxygen to breathe.

• There is a form of oxygen in our ozone layer protects the earth from the sun’s harmful rays.

The Earth

• 70% of the Earth is covered in water.• God has provided many cycles to keep the

Earth in balance.

• Genesis 8:22 says’ “While the Earth remains, planting and harvest, cold and heat, summer and winter, day and night will not cease.”

The Moon

• The moon is a satellite.• A satellite is an object that revolves around

another.• The moon reflects enough light at night when

it is full, that you can see and even cast a shadow.

• The moon was placed in the sky even before man was placed on the Earth.

A Mountainous Moon

• To the eye the moon looks like a giant sponge.

• This is because the surface is pocked with millions of craters.

• Some of the craters are as small as tennis balls and others are hundreds of miles across and several miles deep.

A Mountainous Moon

• The mountain ranges include Mount Epsilon.

• It is higher than Mount Everest.

• There are areas called “maria” which resemble rolling plains.

Phases of the Moon

• The moon revolves around the earth at 23oo mph.

• The moon takes 29 days, 12 hours, and 44 minutes to complete a full cycle.

• This is called a lunar month.

• The same side of the moon faces the earth at all times!!!

Phases of the Moon

• As it moves through its lunar month, parts of the moon are hidden in shadow.

• The new moon is when the moon’s lit side is away from the earth.

• The visible moon gradually “waxes” or grows larger.

• When the moon is half full and half dark…It is called the first quarter moon.

Phases of the Moon

• When we see the entire sunlit moon..it is a Full Moon!

• As the moon waxes, it is said to be in the gibbous phase.

• The second gibbous phase is when the moon is waning or shrinking.

• When the moon is half dark and half light again, it is called the third quarter moon.

Eclipses

There are two different types of eclipses:

1. Solar Eclipse2. Lunar Eclipse

Solar Eclipse

• A solar eclipse occurs when a new moon moves directly between the sun and the earth.

• This blocks the photosphere from view.

• This type of eclipse is rare.

Lunar Eclipse

• A lunar eclipse occurs when the moon is full and the earth moves between it and the sun.

The Moon and Tides

• The moon pulls on the earth.

• This pull (from the gravity from the moon) cause the oceans to rise and fall along the shores.

The Moon and Tides

• High Tide is when the waters along the shore are at their highest point.

• Low Tide is when the waters along the shore are at their lowest point.

The Moon and Tides

• When the sun and the moon are in alignment, they “team” up to pull extra on the tides.

• These are called spring tides.

The Moon and Tides

• Neap tides occur when there is a first-quarter moon or a third quarter moon.

• At this time, the moon and the sun work against each other and the tides are lower!

The End of the Moon!!!
