The three types of unification that can alter political and economic relationship are Incorporating Federal (or con-federal) union and Mixed unions.
<u>Explanation:</u>
- A political union is a kind of state that is made of smaller states. The process of forming such a state out of smaller states is termed unification.
- The unification of states that used to be unified and that is reuniting is known as reunification.
- Types of unification that can alter political and economic relationships are as follows,
- Incorporating union
- Federal (or confederal) union
- Mixed unions.

Answer:
C. Rocks rich in calcium, potassium, and sodium, weather into fertile soil.
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Hence, the statement which is true is that, rocks rich in calcium, potassium, and sodium, weather into fertile soil because these nutrients (chemical elements) are responsible for determining the level of fertility of a soil.

Abstract
Vegetation‐covered relict talus slopes are widespread at the base of glacially steepened rockwalls in Scotland. Investigations carried out on two such slopes, one in the An Teallach massif in Wester Ross, the other on the flanks of West Lomond, Fife, suggest that these slopes accumulated as a result of rockfall in the interval between the retreat of the Late Devensian ice sheet and the end of the Loch Lomond Stadial. Other processes (basal erosion, avalanches and debris flow) were apparently not effective in modifying these slopes during accumulation. During the Holocene, however, rockfall accumulation at these sites has been almost negligible. Present‐day rockwall retreat rates average 0.015mm y‐1 (excluding infrequent large‐scale falls) and are thus low in comparison with rates measured in other environments or calculated for the Loch Lomond Stadial. The main processes operating during the Holocene on these slopes are slope failure, debris flow, gullying and soil creep.
