The occurrence of high-heat flows at the ridge center provides evidence of the existence of rising mantle convection currents.
The solid silicate mantle of Earth moves very slowly as a result of convection currents that transfer heat from the planet's interior to its surface. This process is known as mantle convection. The asthenosphere and the lithosphere at the surface of the Earth together make up the upper mantle.Convection currents develop in the mantle as a result of heat from the core and the mantle itself. Mantle material rises in hot columns slowly. The hotter material spreads out toward the top of the asthenosphere and pushes the colder stuff aside. This cooler substance returns to the mantle.

The picture of the prove is necessary!
Answer:
Causes:
1. Increasing intake or consumption of material goods.
2. material goods that are not durable.
3. a drift to single-use products.
Consequences:
1. groundwater spoilage or contamination from landfills
2. air pollution from waste incineration
3. depletion of raw materials
Solutions:
1. reuse of items whenever possible instead of throwing them away
2. purchase of fewer nonessential goods
3. requirement for manufacturers to recycle their products or services more and more.
