The National Examination Council (NECO Nov/Dec) Has Set The NECO GCE Geography Questions And Answers 2024 paper to take place on 27th November, 2024.
NECO GCE Geography Questions And Answers 2024
(5a)
Underground water refers to water that is found below the earth’s surface in the pores and crevices of rocks and soil, forming aquifers that can be a source of water for wells and springs.
(5b)
(i) Permeable rocks: Permeable rocks are rocks that allow water to flow through them due to the interconnected pore spaces within the rock.
[Draw the diagram below]
(ii) Impermeable rocks: Impermeable rocks are rocks that do not allow water to pass through them due to their lack of interconnected pore spaces.
[Draw the diagram below]
(5c)
(PICK ANY FOUR)
(i) Precipitation levels
(ii) Evaporation rates
(iii) Soil type and composition
(iv) Depth of the bedrock
(v) Groundwater extraction
(vi) Slope of the land
(vii) Climate conditions
(6a)
Glacial action refers to the processes of erosion, transportation, and deposition by glaciers as they move over the land, shaping the landscape through the force of ice and meltwater.
(6b)
(PICK ANY FOUR)
(i) Cirques: Bowl-shaped depressions formed at the head of a glacier.
(ii) Arêtes: Sharp ridges formed between two cirques.
(iii) U-shaped valleys: Wide, deep valleys carved out by glaciers.
(iv) Hanging valleys: Valleys left at higher elevations by the erosion of smaller glaciers.
(v) Horns: Pointed mountain peaks formed by the intersection of several arêtes.
(vi) Glacial erratics: Large boulders transported and deposited by glaciers.
(6c)
(PICK ANY TWO)
(i) Hydraulic action: The force of waves crashing against the coastline, dislodging and eroding rock.
(ii) Abrasion: The wearing away of rock by the impact of sediment carried by waves.
(iii) Attrition: The erosion of rock particles carried by waves colliding and breaking down into smaller fragments.
(iv) Corrosion: The chemical breakdown of rock material due to the acidity of seawater.

(7a)
Vegetation refers to the plant life that covers a particular area, varying in terms of species composition, density, and distribution.
(7b)
Check the diagram below
(7ci)
=MANGROVE=
(PICK ANY THREE)
(i) Found in coastal areas with brackish water.
(ii) Consists of salt-tolerant trees and shrubs.
(iii) Protects coastlines from erosion.
(iv) Provides habitat for diverse marine life.
(v) Adapted to fluctuating water levels.
(vi) Roots help in trapping sediment and nutrients.
(7cii)
=GUINEA SAVANNAH=
(PICK ANY THREE)
(i) Open grassland with scattered trees.
(ii) Supports grazing animals like cattle and goats.
(iii) Has a distinct wet and dry season.
(iv) Vegetation adapted to seasonal rainfall patterns.
(v) Trees shed leaves during the dry season to conserve water.
(vi) Rich in biodiversity with a variety of plant and animal species.

Geographic data refers to information that is spatially referenced, meaning it is tied to specific locations on the Earth’s surface. This data includes various types of information such as coordinates, boundaries, attributes, and characteristics of physical or cultural features.
(8bi)
Maps are a fundamental source of geographical data in GIS. They provide visual representations of spatial information such as boundaries, roads, rivers, and land use. Maps can be used as base layers for GIS applications, allowing users to overlay and analyze other data layers on top of them.
(8bii)
Satellite images are another important source of geographical data in GIS. These images are captured by satellites orbiting the Earth and provide high-resolution views of the Earth’s surface. Satellite images are used for monitoring land cover changes, natural disasters, urban growth, and environmental assessments in GIS.
(8c)
(PICK ANY FOUR)
(i) Spatial data: Geographic data includes information about the location and shape of physical or cultural features on the Earth’s surface.
(ii) Attribute data: Geographic data also includes non-spatial information or attributes associated with spatial features, such as population, elevation, or land use type.
(iii) Topology: Geographic data in GIS maintains spatial relationships between different features, allowing for spatial analysis and modeling.
(iv) Metadata: Geographic data includes metadata that provides information about the source, accuracy, and quality of the data.
(v) Scale: Geographic data in GIS can be represented at different scales, from global to local, depending on the level of detail required for analysis.
(vi) Projections: Geographic data may be referenced to different map projections in GIS to accurately represent the Earth’s curved surface on a flat map.
(vii) Layers: Geographic data in GIS is organized into layers representing different thematic information, such as transportation networks, land cover, or administrative boundaries, which can be analyzed individually or combined for spatial analysis.
