resource interdependence

Crops fulfill a major food need of humans. Exam tip: link biological resources with subsistence.

Resource planning helps in balanced use. Exam tip: link planning with sustainable development.

A dam stores river water in a reservoir. When water is released from a height, it turns turbines to generate hydroelectricity. Thus, controlled use of water is linked with energy production. Option D may seem close, but a dam does not make a river disappear; it regulates its flow. Exam tip: remember the multipurpose roles of dams, such as water storage, irrigation and hydropower.

Erosion reduces soil and increases silt in rivers. Exam tip: write multiple effects of one problem.

Cotton industry uses farm raw material and industrial energy. Exam tip: see the link between agriculture and industry.

Population growth raises land demand for food housing and industry. Exam tip: link population with resource pressure.

Coal has long been used as a fuel and energy source. Exam tip: treat coal as a conventional energy resource.

Irrigation supplies water needed for plant growth and development, so it clearly shows the interdependence of water and vegetation. Melting iron is related to heat, while sand being blown is mainly caused by wind. Exam tip: an example in which water helps plants grow indicates a water–vegetation relationship.

Overuse can affect other resources and the future. Exam tip: link judicious use with conservation.

Excessive withdrawal of groundwater lowers the water table and reduces water available for irrigation. This can directly affect the productivity of farmland and crop production, so option A is correct. Forest resources may also suffer from water scarcity, but agriculture has the most direct link with groundwater-based irrigation in this context. Exam tip: remember the interdependence of water, soil and agriculture.

Energy is needed for machines and production. Exam tip: understand energy as a supporting resource for all sectors.

Milk production needs both animals and fodder. Exam tip: link animal husbandry with biological resource dependence.

Sustainable development considers present and future needs. Exam tip: write balance and conservation together.

A canal carries water to fields for irrigation. Exam tip: understand the link between natural water and human-made means.

Technology helps in finding using and conserving resources. Exam tip: treat technology as part of human resources.

Hydroelectricity makes electricity from moving water. Exam tip: remember the relation between energy and water.

Forests influence water in several connected ways. Their roots and leaf litter help soil absorb and hold rainwater, while vegetation releases moisture and supports parts of the local water cycle. When forests are cleared, infiltration and water storage may decline, runoff and erosion may rise, and the timing or availability of water can change. The exact effect depends on climate, soil, slope and the scale of clearing.

Option A is correct because it states a possible effect without making an absolute claim. Rivers do not always increase, rainfall does not always double, and water remains necessary after deforestation. The word “may” is important: geography questions often test interdependence and ask how one resource can influence another through natural processes.

Mining uses land labour technology and energy. Exam tip: find many resources in an economic activity.

Crops grow well in suitable climate and fertile soil. Exam tip: study natural conditions together.

Agriculture animal husbandry and forest resources are important in rural life. Exam tip: write the livelihood-resource link.
