Question 1
A soil profile shows a layer of clay at a depth of 20 centimeters. If the soil is eroded at a rate of 1 centimeter per year, calculate the time it will take for the clay layer to be completely eroded using the formula: t = d / r, where t is the time, d is the depth of the clay layer, and r is the erosion rate.
Question 2
The following diagram shows a geological map of a region. What is the name of the rock unit labeled 'A'?
Question 3
A map shows a region with a scale of 1:100,000. If the distance between two points on the map is 5 centimeters, calculate the actual distance between the two points in kilometers using the formula: d = s * S, where d is the actual distance, s is the distance on the map, and S is the scale.
Question 4
The Benue Trough is a major geological feature in Nigeria. What is the primary type of rock formation found in this region?
Question 5

Question 12
A river has a discharge of 1000 cubic meters per second. If the river flows for 8 hours a day, calculate the total volume of water discharged in a day using the formula: V = Q * t, where V is the volume, Q is the discharge, and t is the time.
Question 13
The Jos Plateau is a region of Nigeria known for its rich mineral resources. What is the primary type of mineral found in this region?
Question 14
