Rocks are essential for various aspects of life, providing materials for construction, tools, and infrastructure. They also influence soil formation, support ecosystems, and are sources of valuable minerals and fossil fuels vital for economic development.
Compressed Natural Gas (CNG) is primarily composed of methane and stored under high pressure, while Liquefied Petroleum Gas (LPG) consists mainly of propane and butane, stored as a liquid in pressurized containers for easy transport and use.
Fossil fuels, including coal, oil, and natural gas, are formed from ancient organic materials over millions of years. Their formation process is slow, resulting in limited quantities, making sustainable alternatives necessary for future energy needs.
To conserve fossil fuels, we can adopt practices like carpooling, reducing energy consumption at home, using energy-efficient appliances, supporting renewable energy sources, and raising awareness about sustainability within our communities for a greener future.
Using natural resources judiciously is crucial to ensure their sustainability. Responsible consumption helps preserve ecosystems, supports biodiversity, and prevents depletion, allowing future generations to benefit from these essential resources for their survival and well-being.
Human-made resources are materials or products created by humans from natural resources to fulfill specific needs. Examples include buildings, machinery, and vehicles, which are crafted using raw materials like metals, wood, and minerals.
Natural resources like water, air, and forests are replenished through cycles like the water cycle, photosynthesis, and nutrient recycling. These processes ensure that resources are renewed, making them sustainable if managed responsibly.
Other examples of gases include nitrogen, which makes up most of the atmosphere; helium, used in balloons; and methane, found in natural gas. These gases play essential roles in our environment and daily lives.
Water exists in three states: solid (ice), liquid (water), and gas (water vapor). We encounter ice in freezers, drink liquid water, and see steam rising when water boils, showcasing its versatility in everyday life.
