Urbanization

The shift from rural, agricultural life to city life, often characterized by increased population density and economic activity.

Urban Sprawl

The gradual spread of urban areas into surrounding rural zones, typically characterized by low-density residential developments.

Heat Island Effect

The effect of urban areas being significantly warmer than surrounding rural areas due to heat absorption by infrastructure like roads and buildings.

Impermeable Surfaces

Surfaces in urban areas like concrete and asphalt that prevent water from infiltrating the ground and replenishing aquifers.
