The sun makes up 99.9% of the solar systems massSlide 7: THE SUN The sun is mostly made up of the gases hydrogen and heliumSlide 8: Layers of the sun Core SunspotSlide 9: Layers of the sun Core Sunspot The photosphere is the layer where the sunlight we see comes fromSlide 10: Layers of the sun Core Sunspot The chromosphere has a red color because of the presence of hydrogen gasSlide 11: Layers of the sun Core Sunspot The sunspots are dark spot on the photosphere.Slide 12: Layers of the sun Core Sunspot The sunspots have cooler temperatures than other parts of the sunSlide 13: Layers of the sun Core Sunspot Scientists can figure out the temperature of the sun from its colorSlide 14: Layers of the sun Core Sunspot The core (center) of the earth is about 15 million˚C The surface of the sun is about 5,500˚CSlide 15: THE SUN SUN Scientists believe the sun is about 4.6 billion years old They believe the sun will burn for about 5 million more years and then dieSlide 16: IMPORTANCE OF THE SUN Without the sun, there would be no life on earth Heat from the sun warms the earthSlide 17: IMPORTANCE OF THE SUN Plants use the sun’s energy to produce their own food by photosynthesis Animals eat the plants to get food they need to live and growVideo: the sun: Video: the sunVideo: sunspots: Video: sunspotsVideo: the sun’s death: Video: the sun’s deathSlide 21: EARTH The Blue PlanetSlide 22: EARTH The Blue Planet The earth is about 1 million times smaller than the sun Earth is the only planet that has the right temperature, atmosphere and water for life to existSlide 23: Earth is shaped like a sphereSlide 24: The water and the earth’s oceans form the hydrosphereSlide 25: Earth is shaped like a sphere The atmosphere refers to all the gases that surround the earth THE ATMOSPHERESlide 26: The solid rock and soil that cover the earth’s surface is called the lithosphere lithosphereSlide 27: Layers of the earthSlide 28: The earth is made up of three main layers: crust, mantle and the core Layers of the earthSlide 29: The crust is the rocky outer layer of the earth . It is made up of a very thin layer of soil over rock CRUSTSlide 30: Earth is shaped like a sphere crust The crust is the part of the earth we live onSlide 31: CRUST There are two types of crusts : continental crust and oceanic crustSlide 32: Continental crust The continental crust is the part of the crust above the oceansSlide 33: Continental crustSlide 34: oceanic crust The oceanic crust is the part of the crust at the bottom of the oceanSlide 35: CRUST Mantle MANTLE The MANTLE is a thick layer of hot solid rock found below the crustSlide 36: CRUST Mantle MANTLE The MANTLE is about 2900 km thick and is the thickest of all the earth’s layers The temperature of the mantle is about 2200 o CSlide 37: CRUST Mantle MANTLE The rocks in part of the mantle, flow very very slowlySlide 38: MANTLE The crust and mantle have areas of molten (melted) rock called magma Magma on the surface is called lavaSlide 39: EARTH The Blue Planet CORE Core The core is the center of the earth. The core is made mostly of two metals —iron and nickelSlide 40: CORE The core has two layers—the inner core and outer core Outer core Inner coreSlide 41: The outer core is made of liquid metals that flow slowly. It is about 2200 km thick OUTER CORESlide 42: The inner core is an area of solid metal at the center of the earth INNER CORE This part is about 1,250 km thickSlide 43: INNER CORE The inner core is the earth’s hottest part. Its temperature is about 5,000 o C Inner CoreVideo: layers of the earth: Video: layers of the earthSlide 45: Quick Activity How is the earth like a peach? Crust Mantle CoreSlide 46: Quick Activity Skin of the peach is the crust Meat of the peach is the mantle Pit of the peach is the coreSlide 47: WHAT ARE EARTH’S LANDFORMS?Slide 48: LANDFORMS Landforms are natural shapes or features of Earth’s surface Earth has high places and low places, rough places and smooth places.Slide 49: LANDFORMS Some landforms are found both on dry land and on the ocean floorSlide 50: mountains Mountains form when the tectonic plates that make up Earth’s crust push upwards, fold or crack. Mountain EverestSlide 51: Tall mountains rise above the land on each continent The ocean floor also has mountains Mountain McKinley mountainsSlide 52: hills Hills are raised parts of Earth’s surface that are smaller than mountains Hills usually have sloping sides and rounded topsSlide 53: A dune is a hill or a ridge made of sand. Dunes are shaped by the wind, and change all the time dunesSlide 54: plateau A plateau is a large, flat area of land that is higher than the surrounding landCanyons: Canyons A canyon is a deep valley with very steep sides - often carved from the Earth by a river (moving water) The Grand Canyon in Arizona plateauSlide 56: valley A valley is a low place or land between two mountainsSlide 57: valley These valleys are formed as the river wore away solid rock Rivers run through most valleysSlide 58: The Grand Canyon in Arizona A canyon is a deep valley with very steep sides - often carved from the Earth by a river (moving water) canyonSlide 59: Steep sides canyon Deep valleySlide 60: Plains are large flat areas of land. Plains are typically covered in tall or short grasses PLAINSSlide 61: An island is a piece of land surrounded by water ISLANDVideo: earth’s landforms: Video: earth’s landformsSlide 63: HOW DO THE EARTH AND SUN INTERACT?Slide 64: The earth rotates or spins on its axis in a counterclockwise direction The earth completes one rotation in 24 hours (1 day) ROTATIONSlide 65: Earth and the sun night Day The rotation of the earth on its axis causes day and nightSlide 66: Soar system night Day The part of the earth facing the sun has daytime and the other side has night time ROTATIONSlide 67: Soar system night Day As the earth rotates , the side that had daytime will now have nighttime and the side that had nighttime would now have daytime ROTATIONVideo: day and night: Video: day and nightSlide 69: Solar system The earth is also tilted on its axisSlide 70: EARTH’S TILT Summer (more sunlight) Winter The hemisphere tiled towards the sun gets more sunlight (hotter) than the side tilted away from the sun(colder)Slide 71: The tilt of the earth on its axis as it moves around the sun, causes the seasonsSlide 72: SUMMERSlide 73: FALLSlide 74: WINTERSlide 75: SPRINGSlide 76: QUICK QUESTION At what point will it be summer in Mexico? MexicoSlide 77: The earth rotates on its axis and revolves around the sun at the same time Earth and the sunVideo: seasons of the year: Video: seasons of the yearVideo: rotations and revolutions: Video: rotations and revolutionsSlide 80: EARTH The Blue Planet Earth has one moon which revolves around it. The moon is earth’s natural satelliteSlide 81: A natural satellite that orbits around planets MOONSlide 82: THE MOON A natural satellite that orbits around planets. + Natural : NOT made by human beings Satellite : An object that moves around a planet A natural satellite is an object NOT made by human beings that moves around a planetSlide 83: + An artificial satellite is made by human beings and moves around a planet Hubble space TelescopeSlide 84: PROPERTIES OF THE MOONSlide 85: The moon’s surface is covered with rocks and dust. There are plains, mountains and valleys. MOONSlide 86: Because the moon has NO ATMOSPHERE , it has a lot of craters on its surface MOONSlide 87: The moon has no air. MOONSlide 88: MOON The diameter of the moon is about ¼ the diameter of the earthSlide 89: MOON The moon has about 6 times less gravity than the earthVideo: properties of the moon: Video: properties of the moonVideo: moon has no atmosphere: Video: moon has no atmosphereVideo: craters: Video: cratersVideo: gravity: Video: gravitySlide 94: RELATIONSHP BETWEEN THE EARTH AND MOONSlide 95: The moon is earth’s closest neighbor in spaceSlide 96: The moon rotates on its axis as it revolves around the earth MOONSlide 97: It takes the moon the same amount of time to rotate and revolves around the earth MOONSlide 98: It takes the moon 28 days (1 month) to rotate and revolve around the earth MOONSlide 99: Because of this, the same side of the moon always faces the earthVideo: moon’s movement: Video: moon’s movementSlide 101: TIDES Earth and the moonSlide 102: Earth and the moon If you visit the beach, you’ll notice that at certain times, the water is higher on the beach but at other times, it is lower. TIDESSlide 103: What you are seeing are high tides and low tides High tides Low tidesSlide 104: Tides are caused mostly by the pull of gravity between earth and its moon Hide Tide TIDESSlide 105: Each day, the beach will have 2 high tides and 2 low tides low TideSlide 106: TIDES High tides High tides Low tides Low tidesSlide 107: There are six hours between each tide TIDESSlide 108: The highest tide occurs when the earth, moon an sun are lined up TIDESVideo: tides: Video: tidesSlide 110: THE POSITION OF THE SUN, MOON AND EARTH Sun Earth Moon The sun, earth and moon form a system within our solar systemSlide 111: THE LUNAR CYCLE 29½ DAYSSlide 112: THE MOON We are able to see the moon at night because it reflects the sun’s lightSlide 113: From night to night, the shape of the moon looks different The changing views of the moon as it moves around the earth is called the moon’s phasesSlide 114: The moon is not really changing its shape, what changes is the part of the moon that reflects light from the sun to earth LUNAR CYCLESlide 115: LUNAR CYCLESlide 116: The moon has four main phases as it moves around the sun—the new moon , first quarter , full moon and third quarter LUNAR CYCLESlide 117: MOON PHASES Full Moon New Moon Third Quarter Moon First Quarter MoonSlide 118: NEW MOON Moon is directly between the Earth and the Sun. The side of the Moon facing the Earth is dark.Slide 119: Moon is a quarter of its way around its orbit. We see half the lighted half of the moon. FIRST QUARTER MOONSlide 120: FULL MOON During the full moon, the moon looks like a full circleSlide 121: FULL MOON Moon is on the opposite side of Earth from the Sun and the entire side of the moon facing Earth reflects sunlight back to EarthSlide 122: THIRD QUARTER MOON Moon is three-quarters of its way around its orbit. We see half the lighted part of the moon.Slide 124: Between the four main phases , there are other phases where the moon shape is waxing (getting bigger) or waning (getting smaller) LUNAR CYCLESlide 125: WAXING Waxing means getting BIGGERSlide 126: WANING Waning means getting smallerSlide 127: Waxing WaningSlide 128: During these other phases, the moon’s shape could either appear as a crescent or a gibbous Gibbous moon Crescent moonSlide 129: WAXING Waxing Crescent Waxing GibbousSlide 130: WANING Waning Crescent Waning GibbousSlide 132: One complete lunar cycle takes about 29½ daysVideo: phases of the moon: Video: phases of the moonSlide 134: OREOS EXPERIMENT : PHASES OF THE MOONSlide 135: Earth Moon Use a Venn diagram to compare the earth to the moonSlide 136: RELATIVE SIZES OF THE SUN, EARTH AND MOON Sun Earth Moon Compared to the earth and moon, the sun has the largest size, then the earth. The moon has the smallest sizeSlide 137: An eclipse happens when one object in space casts a shadow on another object in spaceSlide 138: In a solar eclipse , the moon casts a shadow on EarthVideo: solar eclipse: Video: solar eclipseSlide 140: In a lunar eclipse , the earth casts a shadow on the moonVideo: lunar eclipse: Video: lunar eclipseSlide 142: Identify the planet labeled M in the picture. Explain your answer M Question 1Slide 143: Partially hidden from view In the shadow of the sun’s corona Cooler than the rest of the sun’s surface Made of the dark-colored minerals Question 2 Sunspots appear to be darker than the rest of the sun’s surface because they are – You do not have the permission to view this presentation.
