Fossil fuels are considered non-renewable because:

• they are abundant and can be replenished quickly.

• they are used up quicker than they can be naturally replenished

• they are a clean and sustainable source of energy.

• they are produced by modern industrial processes.

Ocean acidification is a process that negatively affects marine ecosystems. What causes ocean acidification?

• Natural oceanic processes

• Human activities such as burning fossil fuels

• Volcanic eruptions

• Solar radiation

Explain the process of fracking, including the steps of drilling, injection of fluid, cracking the rock, and extraction. Discuss the environmental risks associated with fracking, particularly water contamination.

• Fracking involves drilling, injecting fluid, cracking the rock, and extracting resources, with risks of water contamination.

• Fracking is a process of extracting solar energy using photovoltaic cells.

• Fracking is a method of planting trees to combat deforestation.

• Fracking is a technique for desalinating seawater to produce fresh water.
