Question 4 Report
List and explain the four major systems of land tenure in Nigeria.
Land tenure refers to the system of rules and regulations that govern the use, ownership, and transfer of land. In Nigeria, there are four major systems of land tenure, which are:
Each system of land tenure has its advantages and disadvantages. For instance, traditional/communal land tenure promotes social cohesion and community development, but may not be conducive to individual investment and economic growth. Individual land tenure, on the other hand, encourages individual investment and economic growth, but may lead to land speculation and inequality. Leasehold land tenure provides a middle ground between individual and communal ownership, but may limit long-term investment and development. Government land tenure can facilitate planned development and control over land use, but may be prone to corruption and misuse of power.

Question 6 Report
(a) What is weathering ?
(b) Enumerate three processes involved in rock weathering
(c) List and discuss briefly the agents of two of these processes
(a) Weathering is the process by which rocks and minerals are broken down into smaller pieces or dissolved by physical, chemical or biological processes, in response to the conditions of the environment in which they exist.
(b) The three processes involved in rock weathering are:
(c) The agents of mechanical weathering are physical forces such as temperature changes, wind, water, and ice. For example, freeze-thaw cycles occur when water freezes in rock crevices and then expands as it turns into ice, causing the rock to crack and break apart.
The agents of chemical weathering are chemical compounds such as water, oxygen, carbon dioxide, and acids. For example, carbon dioxide in the air combines with water to form carbonic acid, which can dissolve minerals in rocks such as limestone, leading to their erosion and breakdown over time. Another example is acid rain, which results from the combination of rainwater with pollutants such as sulfur dioxide and nitrogen oxides, leading to the corrosion and breakdown of rocks and other structures.
