(i) Convectional Rainfall.
(ii) Orographic or Relief Rainfall.
(iii) Cyclonic or Frontal Rainfall.

{EXPAINATION}

(i) Convectional Rainfall: This type of rainfall occurs in the areas intensely heated. Hot/Warm air, accompanied by rise in relative humidity takes place. The rising air becomes saturated and water vapour condenses with cloud being formed quickly.

This results in the heavy rains, accompanied by thunder and lightning. Its features includes;

– It falls within short distances.

– It occurs in the afternoon.

– Convectional rainfall is normally accompanied by lightning and thunder.

(ii) Orographic or Relief Rainfall: In orographic rainfall moist air is forced to rise above a mountain/relief barrier, usually on the windward slopes of mountain. Rising air expands and becomes cooler and relative humidity rises and air becomes saturated. Water vapour condenses, cloud is formed with rainfall on the windward slope and descending air on the leeward side.

Its features includes;

– It is also characterized by ascending and descending wind.

– Windward area has rainfall while leeward side has little or no rainfall.

(iii) Cyclonic or Frontal Rainfall: This type of rainfall is neither caused by orographic nor conventional. It is purely associated with two different air masses of varying temperature difference. It is a convergence of two characteristically different air masses or other physical properties. The meeting of tropical warm air and the polar cold air usually result in this type of rainfall.

Its Features includes;

– It is characterized by fronts and weather system in mid latitudes.

– It covers extensive area and moves from the West to the East in the northern hemisphere and vice-versa in the south.

– Cyclonic rainfall is common between latitude 50°N – 70°N and 50°S and 70°S of the equator.

(4bi)

Lapse rate: Lapse rate is defined as the rate of change in temperature with altitude or the decrease in air temperature as one ascends into the atmosphere. Therefore, Lapse rate is described as 0.65°C per 100m of ascent or 6.5°C per 1000m of ascent.

(4bii)

Inversion: Temperature inversion is defined as the increase in temperature with increasing altitude. Temperature could be lower at sea level, especially in valley ms almost enclosed by mountains than at height above such valleys.

(4biii)

Dew Point: It represents the temperature at which air becomes saturated with water vapor, leading to the formation of dew, fog, or clouds. In simpler terms, it is the temperature at which the air would need to be cooled for water vapor to condense into liquid water.

(i) Arcuate.
(ii) Bird’s Foot.
(iii) Estuarine Delta.

{EXPLANATION}

(i) Arcuate: This delta consists of both coarse and fine sediments and has the shape of an inverted cone. It is crossed by many distributaries. Very good examples of Arcuate deltas are the Niger (Nigeria), Nile (Egypt) and Hwan – Ho.

(ii) Bird’s Foot: This delta consists of very fine materials referred to as “silt” with several long distributaries like the foot of a bird extending into the sea. The Mississippi Delta and the Delta of Omo River in Ethiopia are good examples.

(iii) Estuarine Delta: This delta is formed from materials deposited in the submerged mouth of a river. It takes the shape of the estuary. A typical example of this type of delta can be located in River Seine (Netherlands) and River Vistula (Poland).

(6b)

(i) It is good for transportation. i.e. Ports. (ii) It is equally good for petroleum mining.
(iii) Delta provides a good agricultural land especially for cultivation of rice, oil palm and raffia palm. e.g. River Niger.
(iv) It is also good for fishing.

{CHOOSE ANY BEST 4}

(i) GPS is widely used for navigation in vehicles, ships, and airplanes. It helps users determine their current location, find the best route to a destination, and provides real-time directions, making travel more efficient and convenient.

(ii) GPS coordinates to hide and seek containers, called “geocaches” or “caches,” at specific locations around the world.

(iii) GPS is used to track the movements of wildlife and study their behavior. It also aids in monitoring and managing environmental changes and natural disasters.

(iv) GPS technology is extensively used in surveying and mapping applications, such as creating accurate maps, land surveying, and construction planning.

(v) GPS is used for accurate mapping, crop monitoring, and precise application of fertilizers and pesticides, leading to increased efficiency and reduced environmental impact.

5ai)Weathering is breaking down rocks, soil, and minerals as well as wood and artificial materials by contacting the atmosphere, water, and biological organisms of the Earth.

5aii)water
oxygen
acids
organisms
carbon dioxide

5b)
PICK ANY THREE .
*Solution* : On coming in contact with water many solids disintegrate and mix up as suspension in water. Soluble rock forming minerals like nitrates, sulphates, and potassium etc. are affected by this process. So, these minerals are easily leached out without leaving any residue in rainy climates and accumulate in dry regions.

*Carbonation* : Carbon dioxide from the atmosphere and soil air is absorbed by water, to form carbonic acid that acts as a weak acid. Calcium carbonates and magnesium carbonates are dissolved in carbonic acid and are removed in a solution without leaving any residue resulting in cave formation.

*Hydration* : Minerals take up water and expand; this expansion causes an increase in the volume of the material itself or rock. Calcium sulphate takes in water and turns to gypsum, which is more unstable than calcium sulphate. This process is reversible and long, continued repetition of this process causes fatigue in the rocks and may lead to their disintegration.

*Oxidation* : In the process of oxidation rock breakdown occurs due to the disturbance caused by the addition of oxygen.

*Reduction* : When oxidised minerals are placed in an environment where oxygen is absent, reduction takes place. Such conditions exist usually below the water table, in areas of stagnant water and waterlogged ground. The red colour of iron upon reduction turns to greenish or bluish grey.

(7ai)

Renewable resources: These are natural resources that can be replenished or regenerated within a human lifespan or at a faster rate than they are consumed. They are considered sustainable as they can be used without depleting the resource itself. Examples of renewable resources include solar energy, water, wind power and plant life.

(7aii)

Non-renewable resources: These are resources that come from a finite source that cannot be replenished in a short period of time. Examples include fossil fuels (such as oil and natural gas), uranium, and gemstones.

(7b)

(PICK ANY TWO)

(i) Reduced air pollution and water contamination resulting from the extraction and burning of non-renewable resources.

(ii) Increased energy security since reliance on renewable energy sources reduces the vulnerability to price unpredictability associated with non-renewable resources.

(iii) Increased economic development and job creation since renewable energy requires significant investments in technologies, engineering, construction and operations.

(iv) Reduced water use since non-renewable resources usually require more water for extraction and utilization.

(v) Reduced land degradation due to the extraction of non-renewable resources, such as mining and drilling.

(vi) Reduced greenhouse gas emissions since renewable energy does not typically produce as much carbon dioxide (CO2) as burning fossil fuels.

(2b)

(i) Solstice occurs twice a year while equinox occurs twice a year.

(ii) Solstice is when the sun reaches its highest point in the sky while equinox is when the day and night are of equal length.

(2c)

(ii) They are imaginary circles that run parallel to the equator.

(ii) They are used to measure distance north or south of the equator.

(iii) They are measured in degrees, minutes, and seconds.

(iv) The equator is the largest line of latitude, while the poles are the smallest.
