THE MOON

Formation of the Moon: http://www.cleanvideosearch.com/media/action/yt/watch?

v=GgisZcGTSNA

Formation•The Moon probably formed as the result of a collision between Earth and a Mars-sized object about 4.5 bya when the solar system was forming.

•The material ejected from Earth and from the striking object eventually clumped to form the Moon.

Breaking it down....• Impact- Mars sized body collided with Earth

•Ejection- Parts of Earth’s mantle and crust were ejected into space

•Formation- Gravity causes the ejected material to clump together forming the moon

Exploring the Moon•Astronomers have learned a lot about the

Moon from observations with telescopes.....However, most knowledge of the Moon comes from explorations by space probes and from landings by astronauts.

Exploring the Moon•The first step toward reaching the Moon

was in 1957, when the Soviet Union launched the first artificial satellite, Sputnik I.

•Four years later, Yuri A. Gagarin became the first human in space.

Exploring the Moon•On July 20, 1969, the Apollo program

landed Neil Armstrong and Edwin “Buzz” Aldrin on the Moon during the Apollo 11 mission.

Is the moon far away???•Yes… and no

•It’s the closest object to us in the solar system

•Avg. distance from Earth is 380,000 km (236,121 miles)

•It takes about 3 days in a rocket ship........ It would take 3 weeks if you were traveling at 500 mph

Size

Weight

The Moon’s Surface•Does the moon glow??

•NO.....It’s the Albedo!

•Albedo- the percentage of incoming sunlight that its surface reflects.

•What are the light colored areas?

•What are the dark colored areas? Highlands

Maria

The Moon’s Surface

• Lunar highlands are heavily cratered regions of the Moon that are light in color and mountainous.

•Maria are dark, smooth plains where the craters have been filled with lava from when the moon was tectonically active

The Moon’s Surface• The craters on the Moon,

called impact craters, formed when objects from space crashed into the surface.

• The material blasted out during these impacts fell back to the Moon’s surface as ejecta.

• Some craters have long trails of ejecta, called rays, that radiate outward from the impact site.

The Moon’s Surface•Rilles are meandering, valley like

structures that might be collapsed lava tubes.

The Moon’s Properties•Earth’s moon is unique among all the

moons in the solar system.

•It is one of the largest moons compared to the radius and mass of the planet it orbits.

•It is a solid, rocky body, in contrast with the icy compositions of other moons of the solar system.

•The Moon’s orbit is farther from Earth relative to the distance of most moons from the planets they orbit.

The Moon’s Properties

The Moon’s Properties• The Moon is made up of minerals similar

to those of Earth—mostly silicates!

• The highlands = lunar breccias, formed by the fusion of smaller rocks during impacts.

• The maria = basalt that contains no water.

The Moon’s Properties•Scientists infer from seismic data that the

Moon, like Earth, has a layered structure, which consists of the crust, upper mantle, lower mantle, and core.

What is it like on the Moon?•No air

•No oceans (water)

•No clouds

•No life

•Less gravity- 5/6 (83%) less!!

• If you weigh 120lbs on Earth you would weigh 20lbs on the moon

•Lots of dust

Warm-up 4/2/151. How was the moon formed?The moon was formed as a result of a collision between Earth and a mars-sized object. The debris from the collision clumped together to form the moon.

Bell Work 4/6/151. Is it more beneficial to have a self-inflating life raft or a magnetic compass if you were stranded on the moon?

2. Why??

A self-inflating life raft: You can use the carbon dioxide canister for propulsion!

There is no use for a compass… the Moon has no magnetic field!

The Earth-Sun-Moon

System• http://www.youtube.com/watch?v=ssA7Ew_BQHY

It’s Just a Phase

• Moonlight is reflected sunlight

• From Earth we see different amounts of the Moon’s lit surface

• The amount seen is called a “phase”

• Phases are caused by the changes in the relative position of the moon, Earth and sun.

Eclipses and Tides

•The moon rotates and revolves around the Earth

•The changing relative positions of the moon, Earth and sun cause the phases of the moon, eclipses and tides.

85

Motions of the Moon

•The moon rotates once on its axis in 27.32 days.

•It takes the same time to revolve around the Earth = 27.32 days

85

Synchronous Orbit

•Occur when:

•Moon’s shadow hits Earth OR

•Earth’s shadow hits moon

•When an object in space comes between the sun and a third object it casts shadow on that object = eclipse

•Most months the moon is a little above or below the sun in the sky... but sometimes

•....the moon passes directly between the Earth and sun, blocking light from the sun

•Umbra – the darkest part of the moon’s shadow, it is cone shaped

•Where the point of cone hits Earth, no light from the sun can be seen = total solar eclipse

•Penumbra – larger part of moon’s shadow that is not as dark

•Part of sun is visible through the penumbra

•People in the penumbra see a partial eclipse

•Not safe to look at the sun during a partial eclipse because an extremely bright part of the sun remains visible

•Lunar Eclipses occur during the full moon when the Earth is directly between the sun and moon

•Moon is in Earth’s shadow

•Earth’s shadow has an umbra and penumbra

•When moon is in Earth’s umbra – you see a total lunar eclipse

•You can see total lunar eclipse from anywhere on Earth

•Most lunar eclipses, Earth, the moon and the sun are not quite in line = partial lunar eclipse

•Moon passes partly into the Earth’s umbra

•In your notes, describe the difference between a solar and a lunar eclipse.

Think About:- Positions of the Moon, Earth and Sun- Umbra/Penumbra- Partial vs Total- Moon Phases- Sizes of the Moon, Earth and Sun

•Pair Share: Come up with a statement to share with the class!

•The darkest part of the moon’s shadow, it is cone shaped

2.What is the penumbra?

3.Are they associated with solar or lunar eclipses?

BOTH!

100

•Rise and fall of ocean water that occurs every 12.5 hours

•Water rises for 6 hours and then falls for 6 hours

•Caused by differences in how much the moon’s gravity pulls on different parts of Earth

•High tides occur on the side of the Earth closest to the moon

•due to the moon’s gravity pulling on the water

•They also occur on the side of the Earth farthest from the moon.

•The moon’s gravity pulls on the Earth more strongly than it pulls on the water leaving it behind

• Sun’s gravity pulls on Earth’s waters

• During a new moon – sun, moon and Earth are nearly in a line.

• Gravity of sun and moon pull in same direction

• Combination of forces produce tide with greatest difference between low and high tide, we call it a Spring Tide.

• Spring Tides – occur twice a month during full and new moons

• During moon’s 1st and 3rd quarter, the line between the Earth and the sun is perpendicular to the line between the Earth and moon.

• The Sun’s pull is at right angles to the moon’s pull.

• Produces a Neap Tide = least difference between high and low tide

• Occur twice a month

•In your notes, explain the difference between spring tides and neap tides. Include a diagram!!
