*NECO GCE GEOGRAPHY* (5a) A spring is a natural source of water that emerges from the ground. It is formed when water from an underground aquifer (a layer of permeable rock, gravel, or sand that can hold and transmit water) finds a pathway to the surface. This can happen when the pressure in the aquifer pushes the water upward or when the water flows downhill along a slope. Springs can be found in various forms, such as a gentle trickle or a large gushing flow. (5b) DRAW THE DIAGRAM [https://ibb.co/Qf8j7SP] EXPLANATION An artesian basin is a type of aquifer that is confined between layers of impermeable rock or clay. This geological formation traps water within the basin and creates a natural pressure system. When a well is drilled into an artesian basin, the water is forced to rise to the surface without the need for a pump. This occurs because the pressure in the aquifer is higher than the atmospheric pressure, allowing the water to flow upward.

Topographical modeling is crucial for applications such as watershed analysis, slope assessment, and landform characterization. (ii) Cartographical Modeling: Cartographical modeling focuses on the creation and analysis of maps. This involves modeling the spatial relationships between map features, incorporating elements such as scale, symbology, and spatial distribution. Cartographical modeling helps in designing effective maps for communication and decision-making, considering factors like map layout, color schemes, and visual hierarchy to enhance map interpretation.

*NECO GCE GEOGRAPHY* *NUMBER 6* (6a) CHECK THE DIAGRAM[https://i.imgur.com/nbbWUVL.jpeg] Arcuate deltas form when a river carrying sediment reaches a body of standing water, such as an ocean or a lake. The sediment-laden river water slows down upon entering the still water, leading to the deposition of sediment. The river divides into distributaries that fan out in a triangular or fan-shaped pattern, creating an arcuate (curved) delta. The shape is influenced by wave and tidal action, which redistributes sediment along the coastline, contributing to the distinctive arcuate form. (6b) FEATURES OF A GLACIATED LOWLAND: (PICK THREE) (i) Glacial Till: Unsorted, unstratified sediment deposited directly by glacial ice. (ii) Outwash Plain: Area of glacial sediment deposited by meltwater streams. (iii) Kettle Lakes: Depressions formed by the melting of isolated blocks of ice left behind by retreating glaciers. (iv) Eskers: Long, winding ridges of gravel and sand formed by meltwater streams flowing within or beneath glaciers. (v) Drumlins: Elongated hills of glacial till shaped by the flow of ice, often aligned with the direction of glacial movement. (vi) Kame Terraces: Mound-like landforms created by glacial meltwater deposits on the glacier's surface. (vii) Moraines: Accumulations of glacial debris, including lateral, medial, and terminal moraines. (viii) Glacial Erratics: Large boulders transported and deposited by glaciers, often composed of rock types different from the local bedrock. FEATURES OF A GLACIATED HIGHLAND: (PICK THREE) (i) Cirques: Bowl-shaped depressions formed at the head of a glacier. (ii) Arete: Narrow, steep-sided ridge formed between two cirques. (iii) Horns: Sharp, pointed mountain peaks formed by the intersection of multiple cirques.

(v) Tarns: Small mountain lakes formed in cirques or glacial depressions. (vi) Hanging Valleys: Smaller glacial valleys that intersect with larger U-shaped valleys, often creating waterfalls. (vii) Fjords: Deep, glacially-carved coastal inlets with steep cliffs. (viii) Roche Moutonnée: A rock outcrop smoothed and polished on the up-glacier side and rough and jagged on the down-glacier side due to glacial erosion.

*NECO GCE GEOGRAPHY* (4a) (PICK ANY THREE) (i) Changes in temperature: Climate change can result in increased temperatures, leading to heat stress in animals. This can negatively affect their health, reproduction, and productivity.

Warmer temperatures can promote the survival and reproduction of disease-carrying vectors, such as ticks and mosquitoes, increasing the risk of diseases like Lyme disease or West Nile virus. (iv) Changes in vegetation: Climate change can alter the composition and distribution of vegetation, which can impact animal grazing patterns and the availability of nutritious forage. This can result in reduced animal productivity and the need for supplemental feeding.

*NECO GCE GEOGRAPHY* (3a) Rocks are naturally occurring solid materials composed of minerals or mineral-like substances. They are formed through various geological processes such as cooling and solidification of molten materials (igneous rocks)rocks), or metamorphism of existing rocks (metamorphic rocks). (3b) (i) Mechanically Formed Sedimentary Rock: These sedimentary rocks are formed from the accumulation and consolidation of fragments of pre-existing rocks. The fragments, known as clasts, are transported by various agents such as water, wind, or ice, and then deposited in layers. Examples include sandstone, shale, and conglomerate. (ii) Chemically Formed Sedimentary Rock: These sedimentary rocks are formed from the precipitation of minerals dissolved in water. When water evaporates or becomes oversaturated with dissolved minerals, these minerals can crystallize and form rocks. Examples of chemical rocks include limestone, dolomite, and rock salt. (iii) Organically Formed Sedimentary Rock: These sedimentary rocks are formed from the accumulation and compaction of organic remains, such as plants or animal fossils. Over time, the organic matter undergoes chemical and physical changes, resulting in the formation of organic rocks. Examples of organic rocks include coal, oil shale, and chalk.
