Yr 9 Geograhy
week 4
High-tech Farming
high tech farming includes; robotics,Big data,earth observation,ICT,etc
the good thing about high tech farming is
higher crop productivity, decreased use of pesticides,fertilizer and water which keeps food prices down but it cost alot for high tech farming
water scarcity
water scarcity is not having enough clean sufficient water to share around a region
influencing crop yields
The four most important factors that influence crop yield are availability of water, climate, pests and soil fertility
climate change
a change in regional or global climate patters
food production in Australia
Australia produces a wide variety of fruit, nuts and vegetables. Aus produce; oranges, apples, banana, chestnuts, carrots, tomatoes, potatoes, tropical fruits such as mangoes and pineapples
Week 2
4 figure area referencing
4-figure grid reference contain 4 numbers.The first two numbers are called the easting, represent the x axis. The second two numbers are called the northing and represent the y axis
6 figure grid referencing
Numerical grid references consist of an even number of digits. Eastings are written before Northings. Thus in a 6 digit grid reference 123456, the Easting component is 123 and the Northing component is 456,
scale- ratio scale
Ratio scale is a type of variable measurement scale which is quantitative in nature. Ratio scale allows any researcher to compare the intervals or differences

Week 7
Interconnection
interconnections focuses on investigating how people, through their choices and actions, are connected to places throughout the world in a wide variety of ways, and how these connections help to make and change places and their environments.
Technology connecting nations
Global Trade
Global trade, also known as international trade, is simply the import and export of goods and services across international boundaries.
connections with food and sport
week 5
food security
Challenges to food production
Major challenges to food production – climate change. There are numerous factors that challenge food production. The climate, topography and soil variations within biomes may be challenging for growing food, but the way people change the environment can also have an impact on food production.
the state of having reliable access to a sufficient quantity of affordable, nutritious food.
Africa and food availability
desertification
the process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture.
biofuels
A biofuel is a fuel that is produced through contemporary processes from biomass, rather than a fuel produced by the very slow geological processes involved in the formation of fossil fuels, such as oil
week 3
Continents and ocean
The names of the seven continents of the world are: Asia, Africa, Europe, Australia, North America, South America
The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern Oceans
latitude, longitude and altitude
Longitude is (the vertical line) the angular distance of a point east-west of the Prime Meridian
Altitude is the height of the object from sea level.
Latitudes are the horizontal lines which demarcates earth's climatic variations
Creating climate graphs
climate graphs consist of a red line graph showing average monthly temperature and a simple column graph showing average monthly rainfall figures.
where our food comes from
farming is the source of nearly all of our food and many of our raw materials. In Australia, around 98 percent of the fresh fruit and vegetables, meat, milk and eggs sold in supermarkets are produced by Australian farmers.
week 1
WHAT IS GEOGRAPHY
Geography is a field of science devoted to the study of the lands, inhabitants, features, and phenomena of the Earth and planets.
cultural vs physical feature
Physical geography deals with the study of natural features, such as mountains, rivers, lakes, and plains
BOLTSS
Legend
(key) tells person(s) reading the map what all the symbols
on the map mean
Title
explains the purpose of the map/ what the map is showing
Orientation
shows the direction of north
Source
where the information used to make the map came from
Border
the outline/frame surrounding the map
Scale
tells us how much smaller the map is than the actual area described
week 6
Mental Maps vs GPS
mental map vs GPS
using a GPS is also a good way to improve your mental map as you remember the route you used on the GPS if you use it several times
understanding place
some people have a place that is special to them and has a meaning behind it
connections to place
Spiritual
people feel connected to particular places because
of their beliefs or the way a place makes them feel
Economical
many people feel a connection to particular places because these places provide them with employment or a source of income
Historical
events that happened in the past can also result in people forming special connections to particular places.
Cultural
connections to a place can also be strongly influenced by a range of cultural factors. this can include the perceived historic value of a plc and how that is meaningful for people.
