Which statement describes an advantage of nonrenewable resources? they produce clean energy. they replenish quickly. they are safe for the environment. they are found in abundance throughout the world.

The correct answer is - They are found in abundance throughout the world.

At the moment, there's still an abundance of nonrenewable resources around the world, which combined with their efficiency makes them much easier and most economically justified for usage.

The coal reserves are still in abundance, the oil and natural gas reserves seem to be at a very high level, so their prices globally are still relatively low, so they are the most used.

On the other hand, as the word nonrenewable suggests, they are not renewing, so the time will come when they will be spent and an alternative for them will have to be used, which is why for few decades now, lot of countries have been investing into the development of the renewable resources.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
