Discuss the different types of plate boundaries and the tectonic landforms that develop along them.
Divergent - Plate margins pull apart from each other < > - oceanic ridges, continental rift zones
Convergent - Plate margins move towards one another. > < island arc, continental arc, continental collision zone (rifts, valleys, block mountains)
Transform - Plate margins move sideways past each other ^ faulting and oceanic fracture zones
Define the four pillars of sustainability. How might these be applied to (CHOOSE ONE) either (a) an agricultural production region; or (b) nature reserve.
Environment -We would like resources to be finite however they aren’t. Must consider Consumption vs Conserving Natural Resources (rates), the Disposal of wastes (pollution), Conserving biodiversity and Natural vs Anthropogenic-Influenced landscapes
Culture -Respect of different cultures (religious, heritage, local beliefs) - these specific views can affect the way individuals and groups view and utilise resources.
Economic - our economy can’t be constantly climbing. A reason would be limited resources. Short term flourishing does not equal sustainability. Need to think about how resources are being used in our own backyard, then looking out further (scale). Look at areas like employment, economic growth, efficiency competitiveness and trade.
Social - aim is to reserve social capital by investing in services that form the framework of our society.
When choosing an agricultural production region understanding the full affects of the above concept will allow experts to determine what region is most suitable to the type of production they are wanting to do. Need to find a region where the necessary resources for production are present however that they are abundant enough that we dont deplete them in entirely (conserve) and any pollution created, that the environment will be resilient enough to cope. Is this area appropriate culturally and socially, what effect will producing crop here have on the local citizens and then the region as a whole. What are the positive and negative aspects, will it ultimately be beneficial.
Describe and explain the key features of the A, B and C horizons of a soil profile.
A soil profile is a vertical section of soil like the diagram above. It allows you to examine the structure of soil. A soil profile is divided into layers called horizons. The main soil horizons are A, B, C and D.
Most important for plant growth, the A and B horizons are the top two layers of the soil. The A horizon is where there is most soil life and is sometimes called topsoil. Depending on the soil, the A horizon can be further divided into A1, A2 or Ao (organic). The B horizon is where clays and materials washed down from the A horizon accumulate. This is sometimes called subsoil.
The C Horizon consists of weathering rock.
Describe and explain the key features of the A, B and C horizons of a soil profile.
A is the topsoil horizon of the soil profile, it contains the most life out of all the layers. Additions and losses are the main processes that occur here - clay and other minerals are dissolved and leached out of this region
B is the place where compounds generally accumulate, they are washed down from A. Here we find clay and other minerals that move down to C. We can see transformation processes happening in this horizon
C horizon is the place where processes like oxidation, reduction occurring. It is the holder of parent material. We see minimal additions and or losses in this region.
