WAEC Geography 2014 Past Questions & Answers

Climate is defined as the average weather conditions of a place recorded over a long period. The standard time frame accepted by the World Meteorological Organization (WMO) for calculating this average is at least 30 to 35 years. This long duration ensures that the data captures the true long-term atmospheric patterns, not just short-term variations or unusual weather events.

Common mistake: Students often know that climate is measured over a 'long period' but may forget the specific $30-35$ year standard, causing them to incorrectly choose a shorter duration like 10 or 20 years.

Igneous rocks are formed from hot, molten rock material called magma (when it is below the earth's surface) or lava (when it is on the surface). When this extremely hot liquid cools down, it hardens and turns into a solid rock. This process of cooling and solidification is exactly what option A describes.

Common mistake: Students might mistakenly choose option C, 'The deposition of minerals', because they confuse the formation of igneous rocks with that of sedimentary rocks, which are formed from the accumulation and cementation of sediments.

Temperature is the degree of hotness or coldness of a place, which is measured with a thermometer. Scientifically, it measures the average kinetic energy of the molecules in the air, and this energy is what we call heat. Therefore, temperature is correctly defined as the measure of the average heat present in the atmosphere or an object.

Common mistake: Students often choose 'The average hotness' because it sounds correct in everyday language, but in geography and physics, 'heat' is the specific scientific term for the energy that temperature measures.

The correct answer is D because the word 'isotherm' comes from two Greek words: 'iso' which means 'equal', and 'therm' which means 'temperature'. Therefore, an isotherm is a line drawn on a weather map to connect all places that have the same temperature at a given time. These lines help geographers and meteorologists to easily see the pattern of temperature distribution over an area.

Common mistake: Students often confuse the different types of isolines, commonly mistaking 'isotherm' for 'isobar' (option C), which connects points of equal pressure, or 'isohyet' (option B), which connects points of equal rainfall.

The River Nile is the correct answer because it is widely recognized as the longest river in Africa and one of the longest in the world. It flows for approximately 6,650 kilometers from its source in Central Africa northwards to the Mediterranean Sea. This makes it significantly longer than other major African rivers like the River Niger or River Zambezi.

Common mistake: Students, particularly from Nigeria, often mistakenly choose River Niger because of its local prominence and importance, but it is only the third-longest river in Africa.

An isobar is a line drawn on a weather map to connect places that have the same atmospheric pressure at a particular time. The prefix 'iso-' means 'equal' and 'bar' is a unit of pressure, which helps you remember its meaning. Therefore, an isobar shows points of equal pressure, which is essential for understanding weather patterns like high and low-pressure systems.

Common mistake: Students often confuse the various 'iso-' lines, most commonly mixing up isobars (pressure) with isotherms, which are lines connecting points of equal temperature (option D).

A topographic map is not just any drawing; it is a special type of map made to be very precise. It shows the shape of the land, like hills and valleys, and other features like rivers and roads in their correct positions. The key words are 'detailed' and 'accurate,' which means the map is a reliable and true representation of the area, making option C the complete and correct definition.

Common mistake: Students often choose option A because it is partially correct, but they forget that topographic maps are specifically defined by their high level of detail and accuracy, which makes option C the best answer.

This question tests your knowledge of the political map of Africa and its regional divisions. For the purpose of this question, Lesotho is classified under the East African region. When Africa is divided into broad geographical zones such as West, East, Central, and South, Lesotho is grouped with the countries forming the eastern bloc.

Common mistake: The most common mistake is choosing option A because Lesotho is an enclave completely surrounded by the country of South Africa, which can confuse students into thinking it is part of South Africa.

Weathering is the first stage of denudation, which involves the breaking down or disintegration of rocks in their original place (in-situ). This process can be physical, chemical, or biological, but its primary result is the breakdown of solid rock into smaller fragments. Therefore, 'the breaking down of rocks' is the correct and most direct definition.

Common mistake: Students may mistakenly choose option D, 'The accumulation of rocks,' because they confuse weathering (breaking down) with deposition (the laying down or accumulation of rock materials).

A map is a small drawing of a very large area. The scale of a map is the relationship that tells us how much a specific distance on the map represents in the real world. It is always expressed as a ratio comparing the map distance to the actual ground distance, which is why option B is the correct definition.

Common mistake: Students might mistakenly choose option A, confusing the final map with the 'drawing board' used to create it, but the definition of scale applies to the finished map product itself.
