Study Notes
Meteorology
- The study of the atmosphere and its phenomena, including weather and climate.
The Life Sciences (Biology)
- Botany: The study of plants.
- Zoology: The study of animals and animal life.
- Genetics: The study of heredity.
- Medicine: The study of diagnosing, treating, and preventing illness, disease, and injury.
Scientific Method
- A logical method used to acquire knowledge to explain different phenomena in nature.
- Six basic steps:
- Identify and clearly state the problem.
- Gather information pertinent to the problem.
- (Steps 3-6 not mentioned in the text)
Formation of Solar System
- A star formed in the Milky Way Galaxy, eventually igniting and burning its usable hydrogen and other elements.
- The star exploded, sending matter out in all directions, which eventually cooled and collected to form planets and the asteroid belt.
- The asteroid belt is an early form of the collection of matter that was not able to completely form a planet due to Jupiter's gravity.
- Some early planets may have collided with other early planets, creating larger planets, moons, or space rocks.
Earth's Structure
- The earth consists of several layers: the core, the mantle, and the crust.
- The core is the inner part of the earth, the crust is the outer part, and the mantle is between them.
- The earth is surrounded by the atmosphere.
Dissolution (or Solution)
- Several common minerals, such as halite and calcite, dissolve in water.
- Limestone and marble contain calcite and are soluble in acidic water.
- Marble tombstones and carvings are susceptible to chemical weathering by dissolution.
- Caves and caverns typically form in limestone due to dissolution.
- Speleothems are cave formations made of calcite and form a rock called travertine.
- Stalactites hang from the ceiling, and stalagmites are on the ground.
- Karst topography forms on limestone terrain and is characterized by caves, sinkholes, disappearing streams, and springs.
Air Pollution
- Air pollution occurs when large amounts of dust, soot, bacteria, and other harmful gases enter the air.
- Main sources of air pollution in the Philippines are industry and transportation.
- Major air pollutants include:
- Ozone: formed when nitrogen oxides and volatile organic compounds mix in sunlight, causing health problems such as asthma and sore throats.
- Nitrogen dioxide: a reddish-brown gas coming from power plants and cars, causing coughs, shortness of breath, and a higher chance of health problems with long-term exposure.
