introduction
first person to see the esrth from space and first words
Yuri Gagarin i see earth
TOPOGRAPHIC
MAN MADE ELEMENTS- ROADS CITIES.
NATURAL ELEMENTS- RIVERS MOUNTAINS
ARROW
shows orientation
BIOSPHERE
have life and living things
THEMATIC
information of one subject- use colours and symbols
EXTRA POINTS
500
GLOBES
are acurate representations realistics with details
3 dimensional
have similar shape to the real earth
are not easy to transport nor to read
TEXTS
give us places names and other information
ATMOSPHERE
formed of gases oxigen21% nitrogen78% and carbón dioxide1%
GEOGRAPHIC COORDINATES
are imaginary lines to find the exact location of a place
PIERDES TURNO
:(
MAPS
give informatuion about the planet a smaller área, country...
2 dimensional and flat
distort shapes and images not so realistic
are easy to transport and use
KEY
shiws colours and symbols used in the map
HYDROSPHERE
is all the wáter that exist on our planet: oceans and seas, rivers and lakes,ice, groundwater and wáter vapour.
ELEMENTS OF A MAP

SIZE
DISTANCE
5 BIGGEST PLANET
510 MILLONS KM SQUARE
3 CLOSEST PLANET TO THE SUN
1 SATELLITE NATURAL THE MOON
PARALLELS
ECUATOR
imaginary circles that run east to weast and we use to calculate latitude.
artic circle, north pole, tropic of capricorn, tropic of cáncer, antartic circle, south pole
divides the earth in north and south hemisphere.
SCALE
the diference between the size of someting on the map and it size in real world
LYTHOSPHERE
is the solid part: consist of continents and sumerged land under the oceans and seas
LONGITUDE
the distance from a meridian to the Greenwich meridian we use meridians to calculate it can be east or west using degrees
que hay que hacer para calcular las distancias del mapa y que hay que usar
REGLA DE TRES Y THE RULER
MERIDIANS
Greenwich meridian
imaginary semicircles that run north to south we use to calculate longitude
divide the earth in east and west hemisphere
TYPES OF SCALE
numeric=it is a fraction numerator-unit on the map denominator-real distance in the world
graphic= it is a bar sivides in segments each 1cm
numbers on the bar represent in real world
HOW DO WE REPRESENT THE ESRTH
is not a perfect sphere
is flat at the poles
is geoid
LATITUDE
the distances from a parallel to Ecuator we use parallels to clculate it can be norht or south using degrees
