THE EARTH AND THE MOON UNIT 2

WHAT DO YOU THINK ABOUT ….? WHAT ARE THE EFFECTS OF THE EARTH ROTATION? DOES THE SUN HAVE ANY EFFECT ON THE TIDES? WHY THE MOON HAS SO MANY CRATERS? WHY DOES THE MOON CHANGE ITS SHAPE? …

OUR PLANET EARTH CHARACTERISTICS THIRD PLANET FROM THE SUN LARGER THAN THE OTHER ROCKY PLANETS ONLY ONE SATELLITE ONLY PLANET KNOWN WITH AN ATMOSPHERE WITH OXYGEN, OCEANS OF LIQUID WATER AND LIFE GRAVITY ON EARTH PULLS US TOWARDS THE CENTRE OF THE PLANET HAVE AN INTENSE GEOLOGICAL ACTIVITY

FOUR CONNECTED SPHERES ATMOSPHERE: GASEOUS LAYER THAT SURROUNDS THE EARTH HYDROSPHERE: MADE UP OF WATER BIOSPHERE: WHERE LIVING THINGS ARE FOUND GEOSPHERE: SOLID PART

LIKE OTHER PLANETS, EARTH HAS 2 MOVEMENTS MOVEMENTS AND EFFECTS LIKE OTHER PLANETS, EARTH HAS 2 MOVEMENTS ROTATION EARTH ROTATES AROUND ITS AXIS IT TAKES 24 H TO COMPLETE ROTATION THIS PERIOD ITS CALLED DAY CONSECUENCES OF THE ROTATION: CYCLE OF DAYLIGHT AND DARKNESS, RISING AND SETTING OF THE SUN

REVOLUTION REVOLVES AROUND THE SUN IT TAKES 365 DAYS AND 6 HOURS THIS PERIOD ITS CALLED YEAR CONSECUENCES: THE SEASONS

THE MOON AND ECLIPSES AN ECLIPSE OCCURS WHEN A CELESTIAL BODY IS PARTIALLY OR COMPLETELY HIDDEN BECAUSE ANOTHER BODY IS BLOCKING IT ECLIPSES OCCURS WHEN THE SUN, THE MOON AND THE EARTH ARE ALIGNED TYPES: LUNAR AND SOLAR

LUNAR ECLIPSE OCCURS WHEN THE EARTH PASSES BETWEEN THE MOON AND THE SUN THE EARTH SHADOW BLOCKS THE WHOLE MOON OR A PORTION OF IT

SOLAR ECLIPSE OCCURS WHEN THE MOON IS BETWEEN THE EARTH AND THE SUN THE SUN IS NO VISIBLE FROM A CERTAIN STRIP OF THE EARTH

TOTAL ECLIPSE: THE MOON BLOCKS OUT THE SUN ENTIRELY PARTIAL ECLIPSE: THE MOON CLOCKS OUT A PORTION OF THE SUN ANNULAR ECLIPSE: THE MOON DOESN´T COVER THE SUN COMPLETELY AND LEAVES AN OUTER RING OF LIGHT
