Study Notes
Fossils
- Fossils are remains or imprints of ancient plants and animals preserved in rock, revealing insights into prehistoric life.
- Mould fossils occur when mud or sand hardens, leaving an imprint of an organism.
- Cast fossils form when minerals fill in the imprint left by the bones or plants, creating a rock shaped like the original organism.
Fossil Fuels
-
Fossil fuels are natural energy sources formed from the remains of ancient organisms, transformed by heat and pressure over millions of years.
-
Types of fossil fuels include coal, petroleum, and natural gas.
-
Coal
- Used historically in steam engines, cooking, and electricity generation in thermal power plants.
-
Petroleum
- Includes liquefied petroleum gas (LPG) for home and industrial fuel.
- Petrol serves as fuel for vehicles and aviation; also utilized in producing detergents, plastics, and fibers.
-
Natural Gas
- Compressed natural gas (CNG) is used in power generation, vehicle fuel, and household cooking.
Metals
-
Metals possess varying properties that make them essential for everyday use; common metals include copper, gold, silver, iron, and tin.
-
Iron
- Used in the production of tools and household appliances such as knives, nails, refrigerators, and dishwashers.
-
Gold
- Utilized in jewelry, ornaments, and specialized applications such as spacecraft components.
-
Silver
- Found in jewelry, mirrors, batteries, and as an award medal.
-
Copper
- Key component for electrical wires, plumbing, motors, and cookware.
-
Tin
- Commonly used for food and drink packaging, such as cans.
Understanding Fossils
- Fossils offer historical evidence of extinct life forms, providing insights into their diets based on tooth structure.
- Sharp, pointed teeth indicate carnivory (meat-eating).
- Flat, smooth teeth suggest herbivory (plant-eating).
Earth and its Resources
-
Earth, the third planet from the Sun, supports life and is surrounded by an atmosphere that shields against harmful solar radiation.
-
Contains seven continents: Asia, Europe, Africa, North America, South America, Australia, and Antarctica; and five oceans: Atlantic, Pacific, Indian, Arctic, and Southern.
-
Natural Resources
- Exist independently of human influence; examples: air, sunlight, water, soil, and fossil fuels.
-
Renewable vs. Non-renewable Resources
- Renewable resources are infinite and can be replenished, such as forests and wind.
- Non-renewable resources are finite and may deplete over time, including fossil fuels and minerals.
-
Mining
- Involves extracting metals and other minerals from the Earth for various applications.
