diverse wildlife

Question 17

How are biomes influenced by Climate

Answer 17

-Biomes around the equator are warmer as the sun shines more encouraging plants to grow
-At higher latitudes the sun becomes less intense and more seasonal, influencing the type of vegetation which can grow there

Question 18

Name the 3 things which would influence the local factors of a biome

Answer 18

Altitude
Rock and soil type
Drainage

Question 19

How does altitude have a influence of the local factors of a biome

Answer 19

-The temperature gets colder when height of land increases. For every 1000m temperature decreases by 6.5 degrees Celsius. At high latitudes temperatures can reach below 0
-Precipitation usually increases with height, which alters the vegetation and soil at different altitudes

Question 20

How does Rock and soil type have a influence of the local factors of a biome

Answer 20

Rock and soil type can cause a major difference in vegetation and wild life. When rocks are broken down nutrients are released from rocks into soils which dictates the type of plants which can grow

Question 21

How does drainage have a influence of the local factors of a biome

Answer 21

Drainage is how fast water enters and leaves soil. Drainage is influenced by:
Topography, Soil type, amount of vegetation and Precipitation and temperature. Poorly drained soil can be left waterlogged and boggy

Question 22

What do biomes offer for human resources

Answer 22

Food and water: meat , berries, crops
Energy sources: Fossil fuels, Timber
Materials: metal, wood, rocks

Question 23

How is energy exploited in biomes

Answer 23

Fossil fuels are being extracted at a unsustainable rate, which also emits CO2 gas due to the machinery.
Extracting creates lasting environment damage (e.g. mines)

Question 24

How is water exploited in biomes

Answer 24

The population requires long lasting, clean water sources. However water sources are being depleted faster than being. Ground water stores called aquifers are being depleted at a faster rate than replenishment

Question 25

How are mineral resources being exploited in biomes.

Answer 25

Mineral resources are naturally occurring elements. Some minerals take billions of years to form, but are being depleted at a faster rate for commercial use

Question 26

How does the biosphere maintain green house gases

Answer 26

It regulates the amount of oxygen and carbon dioxide by photosynthesis. Carbon is stored in trees, rocks, permafrost and the sea.

Question 27

How does the biosphere maintain soil health

Answer 27

The biosphere keeps soil fertile through nutrient cycling, which is the movement of nutrients around the biosphere between soils, plants, animals and organic matter.

Question 28

How does the biosphere maintain water regulation

Answer 28

Through the hydrological cycle, Trees intercept, absorb and evaporate water, putting it back into the atmosphere. Then it will fall down again through precipitation

Question 29

Describe the Malthusianism view

Answer 29

Malthus describes how the population will decrease when there is a Positive check (war, famine and disease)

Question 30

Describe the Boserupian view

Answer 30

No matter how large the population grows, the population will always discover new ways to sustain food supplies, such as new agricultural technology and systems to sustain food supplies
