|
|
What is Mass wasting? examples? |
a. Landslides
b. Avalanches
c. Mud Slides |
|
|
What role does water have in assisting mass wasting? |
a. Surface Runoff
b. Soil gets heavier with water in it
c. ------------------------- |
|
|
Why can land clearing/deforestation on steep slopes cause mass wasting? |
a. Loss of trees so no roots left to keep soil together
b. On a diagonal slope making gravity pull it down
c. Water in soil makes it heavy pulling it down |
|
|
What is the link between soil erosion in mountains and flooding in lowlands? Discuss |
All of the mud, sand and silt and it goes to India e.g. Basmati River |
|
|
What is a tree line? What is tundra? |
Tree line- trees can’t grow any further because it is to steep or not enough oxygen Tundra- A vast, flat, treeless region in which the subsoil is permanently frozen. |
|
|
What happens to temperature as altitude increases? Adiabatic lapse rates? |
As you increase in sea level, the air becomes colder and thinner (harder to breathe (Visa versa for decreasing into sea level)) Dry air cools at about 10 C/km moist air usually cools at less than 6 C/km |
|
|
How does 'aspect' (angle of the sun in relation to slope) influence mountains in the -
a. Southern Hemisphere?
b. Northern Hemisphere? |
a. Southern Hemisphere- The sunny side is North b. Northern Hemisphere- The sunny side is south |
|
|
How does altitude influence-
a. Plant communities b. crops |
a. Plant communities- The communities are only able to farm a certain amount of different crops seeing as not all crops can handle the weather conditions. b. crops- Different crops are able to grow in different temperatures meaning some crops will grow in this area and some won’t . |
|
|
What is orographic rain? Rain shadow? |
Orographic rain- Mountain Rain Rain Shadow- a region having little rainfall because it is sheltered from prevailing rain-bearing winds by a range of hills. |
|
|
What examples are there of areas that are wet because of orographic rain? |
a. Water at the bottom because the rain from the top will flow down the mountain ending at the bottom causing flooding
b. Flash flooding around that mountain where the villages are located.
c.------------------ |
|
|
Why are so many villages in mountain areas very compact? |
So that they have more area to farm so that they can make money and have food |
|
|
Why are many mountain villages in poor countries only connected to the outside world by footpaths? |
They don’t have cars or other transport so their is no need build bigger roads (It is to expensive) |
|
|
What crops are well suited to mountain areas? Why? |
All of the crops that are able to grow on the high altitude levels are plants that don't need lots of sun and can deal with the cold conditions. - Root crops - Leafy vegetables - Herbs - Miscellaneous - Oats |
|
|
What is transhumance farming? |
Sherpas bring their live stock ip into the mountains in summer so that they get the high altitude pastures and come back down in the winter. Eg. Switzerland and Australia |
|
|
What is the link between poverty and deforestation in mountain areas? |
When farmers take their live stock high into the mountains for he summer period to make use of the high pastures and back down for the winters. |
|
|
What are some of the animal species that are endangered in mountain areas? |
- Mountain Gorillas - orangutan - pigmy mountain possum (size of the palm of your hand) - snow leopards |
