Industrial Revolution: A period during which predominantly agrarian, rural societies in Europe and America became industrial and urban. Like upgrading from using manual tools for farming (like hoes) to using advanced machinery (like tractors).
Gentrification: The process of renovating and improving a house or district so that it conforms to middle-class taste. It's like giving an old, worn-out teddy bear a makeover to make it look brand new and fancy.
Suburbanization: The process of population movement from urban areas to suburbs. It’s like when the ants decide the anthill is too crowded and start creating smaller colonies around the main hill.
