Established during the middle ages, guilds were associations of skilled artisans designed to institute quality standards, establish training programs, and set prices in industries such as glassblowing or masonry. what most likely happened to the guild system following industrialization? a. guilds likely incorporated new skilled artisans with industrialization-era skills. b. guilds likely became more powerful as fewer people learned trade secrets for these industries. c. guilds likely became less powerful as artisans were replaced by machinery. d. guilds likely expanded to include factory workers, laborers, and unskilled workers.

The correct answer is C. Guilds likely became less powerful as artisans were replaced by machinery. During the Industrial revolution mass production allowed businesses to produce larger quantities using less capital. They needed less workers when they began incorporating machines that could not only produce more products quicker, but could also produce them uniformly. This meant that fewer artisans would have been needed to make certain products.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
