This is an average of 87 gallons per person a day. There is a limited amount of water available. Most of the water on the planet is salt water in the oceans. This water is too salty to drink or to use for farming. Ocean water can go through a costly desalinization process that makes it useful for drinking, industry, or farming.
Water is an important resource for food as it is the habitat of fish.
Minerals are a non-renewable resource found in rocks, soil, or in the ocean water. Minerals that are mined for profit from rocks are referred to as ores. Metallic ores contain metals, such as copper, aluminum, gold, silver, and iron. Non-metallic ores are ores such as sulfur, limestone, and quartz. Fossil fuels were made through heat, pressure, and time acting together on the remains of ancient plant and animal life.
