(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.

(8a)
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.
