• The Hubble Telescope was pointed at a dark part
  of the sky
• Located in the constellation Fornax, the region
  is so empty that only a handful of stars within
  the Milky Way galaxy can be seen in the image.

The Great galaxy in Andromeda a spiral galaxy
similar to our own

Our sun is but one single middle sized and middle
aged star hanging out along the edge of average
sized galaxy
5
Our Sun, the source of life on Earth is but one
of millions.

Our Earth is planet 3 in a system of Nine
Planets
8
Comparative orbits of the local solar system.
Between the orbits of Mars and Jupiter is a broad
band of material, the asteroid belt.
9
Images of the inner planets relative sizes are
shown. The image of Venus is from a RADAR mapping
mission as the Venusian surface cannot be seen
through the thick atmosphere.
10
Comparatively, we are dealing with a very small
part of a very big system..
11
The atmosphere behaves like a fluid, with
currents and eddies. Weather is a product of
these atmospheric movements.
12
The Atmosphere of the Earth is only about 20
miles thick. Were the Planet the size of a peach
the lower atmosphere (3 miles) would be thinner
than the fuzz of that peach. The Earth's
atmosphere is 77 nitrogen, 21 oxygen, with
traces of argon, carbon dioxide and water.

The lower atmosphere is where life is possible
and where weather occurs.

Hydrosphere 71 Percent of the Earth's surface is
covered with water. Earth is the only planet on
which water can exist in liquid form on the
surface.
17
Lithosphere
Beneath the surface the Earth is believed to
contain an extremely hot core. This heat extends
upward into the mantle where the heat is
sufficient to produce plastic behavior.
18
Unlike the other rocky planets, the crust of the
Earth is divided up into a number of plates
that appear to float on the plastic mantle
below.
19
Collisions between tectonic plates cause the
crust to fold
20
Or force magma to the surface forming volcanic
landforms

22
At diverging margins new crust is being
created. At converging margins the crust is
re-melted. The continents float like chocolate
chips on the tectonic cookie
23
The Biosphere consists of all living organisms on
Earth. Animals exist in very close relationship
with plant communities

So here we have our Earth, fundamentally the only
planet we have explored GEOGRAPHY Is the
science of describing this planet
literally, Writing about Earth
26
SUBJECT MATTER
From the Greek Language geo Earth graphia
description or depiction Eratosthenes, a 3rd
century B.C. Greek Scholar and chief librarian at
the famous Library of Alexandria was perhaps the
first person to use the term Geography.
27
DEFINITIONS
The world and all that is in it. Spatial
perspective on people, places and
environment. Geography is a social science that
focuses on the spatial distribution of human and
physical phenomena. The science and art of
understanding the spatial relations among people,
place, and environment. Geography is the study of
pattern and processes associated with the Earth.
The focus of the geographer is on spatial
patterns and how phenomena that share common
space interact spatially.

DEFINITION
Geography is the study of people, places and
environments. But more than that, it is a way of
looking at the world and asking why it works ( or
doesnt work ) and the way it does work. It is
more than where, but why there. It is looking at
issues from a spatial perspective and inquiring
about them.
30
Why What is Where?andWho Cares?
An alternative definition of geography
developed by Dr.s McKnight and Strong during a
snowball fight along the empty streets of
Washington DC.
31
The geographic eye

• Learning to SEE space and spatial relationships.
• An important part of training this skill is
  learning to communicate spatial relationships.

32
Sketch Mapping
A sketch map gives a geographer the opportunity
to selectively present information. A sketch
map can easily be seen as a perceptual map how
does one perceive the world? this is embodied in
a sketch map.
33

• Sketch mapping is graphic communication in its
  purest form.
• Although very rarely considered, the basic rules
  of cartography should be remembered.
• Scale, direction, angular fidelity, symbolism,
  simplicity are all useful to remember.
• These are the maps you sketch on the back of a
  napkin to give someone directions.

34

• A sketch map follows some basic procedures
• establish the limits of the area to be mapped
• Layout a basic referencing system and make sure
  the map follows these references
• Focus on the vital elements and make these the
  primary focus of the map
• Label features
