1 The moon formed when a large object collided with Earth. The material mixed and some broke off to form the moon. This is called the Impact Theory. The moon formed when Earth was still young and is currently 4.4 – 4.45 billion years old. Rogue planet colliding with Earth. Elle Grant The moon revolves around Earth and is, on average, 384,399 km away from Earth. No. The moon’s orbit around Earth isn’t a circle, so its distance from Earth varies. At Perigee (nearest distance) the moon is about 363,104 km away. At Apogee (farthest distance) the moon is about 405,696 km away. How big is the moon? -The diameter of the moon is 3476 km (2160 miles) across. -The surface area is 38 million km2 (14.6 million miles2). -The density of the Moon is 3.346 g/cm3. -The mass of the Moon is 7.347 x 1022 kg. -5th biggest moon in the Solar System -2nd densest moon in the Solar System • • • • • • • Travels around the Earth in a counterclockwise orbit Orbits at a speed of 2,288 miles per hour Travels at different speeds at different parts of its orbit Orbit is eliptical Period of Rotation: 29.5 days Period of Revolution: 27.3 days Only one side of the moon is visible from Earth because it rotates on its axis at about the same rate at which it orbits the Earth Layers of the Moon Crust: -Moon’s dry, dusty, and rocky outer layer/surface -Moon rocks samples show much of aluminum and titanium Rigid Lithosphere Mantle: -A rocky layer that’s not hot enough to flow -Hard shell of 620 miles thick Non-rigid mantle: -Asthenospheric layer; rock is less rigid than in a lithosphere but rigid enough to transmit seismic waves -Deepest parts are hot enough to flow Outer Core: -liquid iron outer core -radius: 205 miles Inner Core: -Sold iron-rich rock inner core -radius: 150 miles By studying the rate of spin of a body, as well as determining the mass of the body, scientists can figure out if the body must have a core and how large that core must be. Moon Tectonic Activity, Rock Cycle, and Volcanism • • • Tectonic Activity – Fewer moonquakes than earthquakes and moonquakes have much less magnitude. – Moon has solid mantle=no convection=no tectonic activity=fewer moonquakes + moonquakes with less magnitude Volcanism – There is a lot of lava on the moon but very few volcanoes. – fissures, long cracks in the moons surface, formed and allowed magma to seep onto the surface a long time ago – Conclusion of Volcanism on Moon: There were no large volcanoes on the moon, the lava came from fissures in the moon’s surface. Rock Cycle – No rock cycle on the moon because the moon has no tectonic activity, weathering, or erosion – No weathering and erosion on the moon because there is no water or wind Lunar Highlands -The lunar highlands are the lighter areas on the surface of the moon. -They are located everywhere around the moon -The lunar highlands are composed of light aluminum-rich material. The rocks are mostly Anorthosite, a type of igneous rock that is not common on Earth due to Earth’s tectonic activity. Lunar Highlands •The Lunar Maria are a series of black basaltic plains on the lunar surface, caused by volcanic activity millions of years ago. •They are very vast, and in total, cover 16 percent of the moon’s surface. They are visible to the naked eye from earth even. • Early astronomers actually thought they were seas and thus named them “Maria” (literally “seas”). • Their mineral composition is mainly basalt, in the form of mafic igneous rocks. They are classified into three groups based on the basalt: high-Ti basalts, low-Ti basalts, and very Low-Ti (VLT) basalts. (Ti=titanium) The Moon’s Gravity The Moon’s average gravity is 1.622 m/s², whereas the Earth’s gravity is 9.78 m/s². The gravity of the Moon is precisely 83.3% less than that of the Earth. This is because the Moon has about ¼ the mass of the Earth, and the less the mass, the less the gravity. If you weighed 100 pounds on Earth, you would only weigh 16.6 pounds on the Moon! The Moon’s Magnetic Field Earth’s magnetic field is created by convection (hotter/less dense material rises while colder/more dense material sinks). Moon is too small for convection to take place. Magnetic field generated as moon’s core and mantle rotate (on slightly different axes) and since the boundary between them is not spherical, their motion mixes the fluids around. Moon does have poles, although they are a lot weaker than Earth’s magnetic poles. Lunar Atmosphere JP Park •Until recently, most everyone accepted the conventional wisdom that the moon has virtually no atmosphere •Lunar Atmospheric Composition Experiment (LACE) detected small amounts of a number of atoms and molecules including helium, argon, and possibly neon, ammonia, methane and carbon dioxide •Moon: Thin atmosphere, molecules don’t move a lot Earth: Thick, dense atmosphere, molecules collide into each other •The temperature of the moon in the daytime happens to be very hot, around 100 degrees C. At night, it becomes cold, as cold as minus 173 degrees C. •This occurs because our moon has no atmosphere to hold in its heat at night or stop its surface from becoming hot during the day. •Because the moon has no atmosphere, this means there is no wind and weather. You cannot have weather of any kind without an atmosphere. Apollo 1- The mission was supposed to be the first crewed flight of Apollo, the astronauts died when a fire burned through the command module. Apollo 7- Apollo 7 was the first manned earth orbit flight test of the Command and Service module. The capsule and crew were safely recovered in the Atlantic Ocean. Apollo 8- NASA's three astronauts became the first humans to see the moon's far side. They orbited the moon but didn’t land. Apollo 9- The first flight test of the complete lunar landing mission. During ten days of operations, the crew demonstrated all Apollo mission maneuvers. Apollo 10- The first lunar flight of the complete spacecraft. Had a fully configured lunar module. Apollo 13- It was to be the third lunar landing attempt, but the mission discontinued after the explosion of the oxygen tank. Apollo Missions that Landed on the Moon Apollo 11 : Featured the first man on the moon which was Neil Armstrong (“The Eagle has landed…”) Apollo 12 : Was created to drop off Apollo Lunar Surface Experiments Package, or ALSEP, to be left on moon’s surface for long period of time Apollo 14: Recovery from failure of Apollo 13 and had the same landing site as Apollo 13. Apollo 15: First launch of a lunar roving vehicle (LRV) to carry 2 astronauts and first launch of satellite from space Apollo 16 – First use of moon as astronomical observatory Apollo 17 – First geologist on lunar surface and greatest amount of lunar samples returned to Earth How many Moon rocks were brought back to earth? Where are they? Apollo 11, 12, 14, 15, 16, and 17 brought back 381.69kg (841.6lb) of Moon Rock. Also, Soviet Luna 16 and 20 missions brought back another 130g to Earth. 5kg of Moon rocks were sent to museums around the world for display, and only 5.1% are allowed for scientific study and research. The rest is preserved for posterity. Thad Roberts Thad Roberts was very outgoing and intelligent. He was hired to work at NASA. He became a Geo-astrophysicist. He stole some moon rocks to impress his girlfriend and then he tried to sell them. He was sentenced to 100 days in federal prison. Sex on the Moon is a book written about his exploits.
