Question 1C
Volcanoes Discuss the positive impacts of volcanoes.
Worked Solution & Example Answer:Volcanoes Discuss the positive impacts of volcanoes. - Leaving Cert Geography - Question 1C - 2018
Step 1
Identify three positive impacts of volcanoes
Answer
-
Fertile Soil: Volcanic eruptions produce ash that enriches the surrounding soil with minerals, leading to highly fertile land. This can greatly enhance agricultural productivity and support local economies by providing ample food supply.
-
Geothermal Energy: Volcanic activity can be harnessed for geothermal energy, a renewable energy source. Countries like Iceland utilize geothermal energy from volcanic regions to power homes and industries, promoting sustainable energy practices.
-
Mineral Resources: Volcanic areas are often rich in valuable minerals such as sulfur, copper, and gold, which can be extracted for various industrial and economic purposes.
Step 2
Discuss the importance of fertile soil
Answer
The fertile soil resulting from volcanic ash is a crucial benefit because it enhances crop yields, making agriculture more productive. This increased productivity can lead to food security and improve the economic conditions of communities living in volcanic regions. Historically, many civilizations have thrived in areas with volcanic soil due to this agricultural advantage.
Step 3
Discuss geothermal energy utilization
Answer
Geothermal energy derived from volcanic regions represents a sustainable energy source that reduces dependence on fossil fuels. By capturing the Earth's heat through geothermal plants, communities can reduce greenhouse gas emissions, combat climate change, and ensure a stable energy supply. This has significant implications for both environmental sustainability and economic resilience.
Step 4
Discuss mineral resources
Answer
The extraction of minerals from volcanic regions contributes significantly to local and national economies. These minerals are critical for various industries, including construction, technology, and manufacturing. Furthermore, the economic activities generated from mining and related industries can provide jobs, improve infrastructure, and enhance overall community development.
