    LESSON OBJECTIVES: 1- Learn about the Earths structure.

    2- Identify and locate continents and oceans

    3- Recognise the main continental relief forms and explain their formation (Earths

    internal forces and external agents)

    4- Describe the distribution of the continental waters, their origin and forms

    5- Recognise the relief forms in coastal areas and on the ocean floor.

    6- Identify the origins of earthquakes and volcanic eruptions and learn about the

    consequences of both phenomena

    7- Draw and/or interpret maps, drawings, photographs, texts, charts related to the unit

    content

    8- Understand the consequences of volcanic eruptions and earthquakes on peoples lives

    PLANET EARTH

    FACTS ABOUT THE EARTH:

    3RD PLANET FROM THE SUN

    510 KM2

    30% LAND AND 70% WATER

    THE BLUE PLANET

    ITS AN IMPERFECT SPHERE (FLAT AT THE POLES)

    2 HEMISPHERES DIVIDED BY THE EQUATOR

    SPECIAL CONDITIONS THAT MAKE LIFE POSSIBLE

    SURFACE TEMPERATURE

    PRESENCE OF LIQUID WATER (USEFUL FOR PEOPLE, ANIMALS, PLANTS)

    THE ATMOSPHERE PROTECTS US FROM SOLAR RADIATION

    MOVEMENTS OF THE EARTH TWO MOVEMENTS

    ROTATION: ON ITS OWN AXIS, WEST-->EAST DIRECTION; 24 HS

    CONSEQUENCE: Succession of days and nights

    REVOLUTION: AROUND THE SUN, WEST-->EAST DIRECTION; 365 DAYS, 6 HS

    (LEAP YEAR (366 days) EVERY 4 YEARS: 6 HS x 4 years: 24hs 1 extra day: 366

    days)

    CONSEQUENCE: Eclipses; the 4 seasons (thanks to the inclination of Earths

    axis)

    SOLSTICES: Summer: Suns rays strike vertically in one hemisphere

    (High temperature, many hours of light) Winter in the opposite

    hemisphere (Low temperatures, few hours of light)

    EQUINOXES Spring/autumn: Suns rays strike at an angle (mild

    temperatures, days and night of similar length)

  • Rotation

    How long does it take the Earth to make a complete rotation?

    What is the main consequence of rotation? Why does this happen?

  • Revolution

    How long does it take the Earth to complete one revolution?

    What is the main consequence of revolution?

  • Parallels: They go from 0 to 90 south and north

    Important parallels: the Equator, Tropic of Cancer and Capricorn, Artic and Antarctic Circles.

  • Meridians: They go from 0 to 180 east and west from Greenwich

    Important Meridians: Meridian 0 or Greenwich

    GEOGRAPHIC COORDINATES

    LATITUDE: Distance between any point on the Earths surface and parallel 0

    LONGITUDE: Distance between any point on the Earths surface and meridian 0

  • Latitude

    What is latitude?

    What units to do we use to measure latitude?

  • Longitude

    What is longitude?

    What is its maximum value?

    TIME ZONES

    THEY ARE SET TO ESTABLISH AN OFFICIAL TIME IN EVERY COUNTRY

    The Earths sphere (360) into equal sections of 15 (24 x 15=360)

    Each time zone equals one hour (Reference: GMT: Greenwich Mean Time)

    International Date Line

    MAPS A REPRESENTATION ON A PLANE OF PART OF THE EARTHS SURFACE

    CARTOGRAPHY IS THE ART OF MAKING MAPS

    MAP SCALE:

    PROPORTION BETWEEN AN AREA REPRESENTED ON A MAP AND ITS REAL SIZE

    SMALL-SCALE MAPS: REPRESENT LARGE AREAS WITH LITTLE DETAIL

    EXAMPLE: A WORLD MAP

    LARGE-SCALE MAPS: REPRESENT SMALL AREAS WITH MORE DETAIL

    A MAP OF A PROVINCE

    TWO TYPES OF SCALES

    NUMERICAL: EX: 1/50000

    LINEAR/GRAPHIC:

  • Map scale

    What is map scale?

    What is the scale of this map?
