What are natural resources?
Natural resources are materials or substances that occur naturally in the environment.
Define the term biotic resources.
Biotic resources are natural resources obtained from the biosphere, which are living things that can reproduce, such as plants, animals, and fungi.
What are abiotic resources?
Abiotic resources are natural resources obtained from the lithosphere, hydrosphere, and atmosphere, which are non-living things such as soil, sunlight, and rocks.
What type of resource cannot be remade or replaced because the process takes too long? These resources are finite and will eventually run out.
A non-renewable resource cannot be remade or replaced because the process takes too long.
Define the term renewable resources.
Renewable resources are resources that are infinite and will not run out, such as wind, solar, and biomass.
True or False?
Humans consume more natural resources each year than the Earth can sustain.
True.
Since the 1970s, human use of natural resources has created a global ecological deficit, where more natural resources are being used each year than the Earth can sustain.
What does exploitation of natural resources mean?
Exploitation of natural resources refers to the use of natural resources by humans for various purposes, such as energy, food, and water.
Define freshwater resources.
Freshwater resources are sources of water that are not salty or brackish, such as rivers, lakes, and groundwater.
What are the three sources for water abstraction?
The three sources for water abstraction are:
Aquifers
Lakes
Rivers
True or False?
Overfishing can lead to a reduction in fish populations.
True.
Overfishing occurs when fish reproduction rates cannot replace the fish caught, leading to a reduction in fish populations and impacting marine ecosystems.
Where are the main reserves of oil, gas and coal found?
The main reserves of oil and gas are found in the Middle East, Russia, and the United States, while the main coal reserves are in Russia, Australia, India, and the USA.
What type of rock is formed by the deposition and solidification of sediments, such as sandstone, shale, and limestone?
Sedimentary rocks are formed by the deposition and solidification of sediments, such as sandstone, shale, and limestone.
What are minerals?
Minerals are naturally occurring solid inorganic substances with a specific chemical composition and atomic structure.
How much of the world's land surface is used for agriculture and forestry?
The distribution of agriculture and forestry is dependent on climate and soil conditions. Over 44% of the world's land surface is used for agriculture, and approximately 31% is covered by forests.
What is forestry?
Forestry refers to the management of forests, including the study of trees, their cultivation, and the management of forest resources.
True or False?
The UK has significant reserves of coal, oil, and gas.
True.
The UK has coal reserves in Yorkshire, South Wales, Derbyshire, and Nottinghamshire, and oil and gas reserves were discovered in the North Sea in the 1960s.
What is the distribution of forests in the UK?
The largest areas of forests in the UK are found in Scotland, and forest coverage has increased from a low of 5% in 1900 to 13% in recent years.
Define arable farming.
Arable farming is the cultivation of crops, such as grains, vegetables, and fruits, on plowed land.
State the meaning of water surplus.
A water surplus is where the supply of water exceeds the demand for water in a given area.
True or False?
The UK has higher precipitation in the south and east regions.
False.
The UK has higher precipitation in the north and west regions, while the south and east regions have lower precipitation and higher population density, leading to a water deficit.
Define the term irrigation.
Irrigation is the artificial watering of crops.
Where in the world will the greatest increase in energy demand be over the next 10 years?
The greatest increase in energy demand will be in China, India and Southeast Asia.
