Answer:
Geomorphological processes and resultant topography are related with glacial, aeolian, fluvial and ground water movement.
- Outwash plain: <em>deposited mostly by water from melting glaciers.</em>
- Sand dunes: <em>not related to glaciation</em>
- Offshore bar: <em>not related to glaciation</em>
- Moraine: <em>deposited by glaciers</em>
Explanation:
Each and every geomorphological process has three types work. For e.g. erosional work, transportational work and depositional work.
- Outwash plain produced by fluvio-glacial depositional work where firstly glaciers melt and then the water flows and deposits sediments in a flat area.
- Moraine produced by glacial deposition. Glaciers carry sediments (pebbles, cobbles) and when it deposits in the valley floor it results a distinguished landform i.e. moraine.
- Sand dunes produced by aeolian action (depositional work). When wind receives obstacle in the form of tree or stone in its way it deposits sand in desert area and produce sand dunes.
- Offshore bar produced by marine processes. when sediments deposited in the coastal area in a huge quantity and friction take place between the wave and sea floor it creates offshore bar.
The maximum amount of electricity that on-shore wind farms can produce is 200 kWh/d per person under ideal conditions i.e. covering the entire nation in wind turbines.
The following steps are taken in the energy conversion process while producing electricity from wind turbines:
First, the wind strikes the turbine blades and transfers its kinetic energy to them. A generator is attached to the turbine blades. The generator shaft is turned by the kinetic energy of the turbine blades.
The generator then produces electricity out of the kinetic energy of the blades.

Answer:
the soil remains above the bedrock that weathered to form the soil. Soil that remains above its parent rock is called residual soil.

Explanation:
New Zealand is located in one of the most tectonically active regions of the world, the pacific ring of fire.
Volcanic activities is produced from uprising magma through the earth. They usually occur around plate boundaries on the surface of the earth.
New Zealand sits around an area where the Pacific plate subducts under the Indo-Australian plate. As the subduction occurs, the rocks beneath undergoes partial melting leading to the formation of magma. The magma reaches the surface in landward regions away from the subduction margins and series of volcanic arcs can form. These series of volcanoes typifies the tectonic setting of New Zealand and it is responsible for the vast volcanic activity in the region.
