Taking resources from the land or the sea
Economic Activity
Economic Activity can be divided into 3 categories. These are;
1. Primary Economic Activity2. Secondary Economic Activity3. Tertiary Economic Activity
What is Primary Economic Activity?
Primary economic activity involves taking natural resources from the land or the sea.
Q. What is a natural resource? Q. What natural resources are available from the land or the sea?
Primary Economic Activity
We now know that Primary economic activity involves taking natural resources from the land or the sea. We take resources from the land and the sea in the following ways;
1. Farming2. Fishing3. Forestry4. Mining5. Quarrying
Q. Many people work in the primary economic sector. List some jobs that people do in the primary economic sector.
Primary Economic Activities
Primary Economic Activity In developing (poorer) countries many people are employed
in primary economic activities.
Q. Why do you think this is?
In developed (rich) countries less people are employed in primary economic activities.
Q. Why do you think this is?
Natural ResourcesNatural resources are things provided by nature
which are useful to people.
Q. Make a list of things provided by nature which are useful to people.
Natural Resources
Natural Resources
Types of Natural Resources
There are 2 types of natural resources.
1. Renewable resources2. Non-renewable resources
Q. How do you think these types of resources are different?
Renewable Resources
Renewable resources are resources that can be used over and over again. With careful management, they will not run out.
For example, if we cut down trees to make wood, we can plant new trees to take their place.
Q. Can you think of any other examples?
Other examples include water, fish, plants/crops.
Q. Explain why these examples are renewable resources.
Non-Renewable Resources
Non-renewable resources are resources that can only be used once. Each time such resources are used less of that resource is left for the future. Non-renewable resources will eventually run out.
Q. Can you think of any examples of non-renewable resources?
Examples include coal, oil, gas, and peat.
Q. Explain why these examples are non renewable resources.
Water – A renewable Resource
It can be reproduced and replenished
BUT only if it is properly used and conserved
The Hydrological Cycle is the continuous movement of water between the land, the sea and the air
This is how nature cleans and renews our water supply
Water – A Renewable Natural Resource
The Water Cycle
Condensation
Run Off
Evaporation
Precipitation
Water – A Renewable Natural Resource
More than 2/3 of the earth is covered in water. However, only a very small amount of the water on our planet is fresh water.
Fresh water is what we need for drinking, washing, and cooking. Fresh water is also needed for irrigating farmland and for
making things in factories.
In some countries, almost everyone has access to safe drinking water. However, in other countries many people do not have access to safe drinking water.
Q. List 5 countries where everyone has access to safe drinking water. Q. List 5 countries where less than 33% of people have access to safe
drinking water.
Water Use
Water Use and Wealth
People who live in wealthy countries use much more water than people who live in poor countries.
Q. Why do you think this is?
Q. In Ireland we do not have to pay for the water we use at home. Is this a good thing?
How do we get our water?
Water Supply
Water Supply in DublinMost of Dublin’s
water comes from Co. Wicklow.
A number of reservoirs have been built to store water which is then pumped to houses in Co. Dublin
Water Quality
Water can be polluted by farming, and industrial activity.
Q. Why is the river quality in the Northwest of Ireland better than in the East of Ireland?
Q. What can be done to help ensure that water quality is improved in the East of Ireland?
Water Contamination
