Introduction to Biology and Geology

Biology

• Study of living organisms and their interactions with each other and the environment
• Branches:
  • Botany: study of plants
  • Zoology: study of animals
  • Microbiology: study of microorganisms
  • Ecology: study of relationships between organisms and their environment
• Key concepts:
  • Cells: basic units of life
  • DNA: genetic material
  • Evolution: change in species over time
  • Ecosystems: communities of living and non-living components

Geology

• Study of the Earth's physical structure, composition, and processes
• Branches:
  • Petrology: study of rocks
  • Mineralogy: study of minerals
  • Geophysics: study of Earth's internal and external physical processes
  • Paleontology: study of fossils and ancient life
• Key concepts:
  • Plate tectonics: movement of Earth's crust
  • Rock cycle: formation and transformation of rocks
  • Weathering and erosion: breakdown and transport of rocks and soil

Astronomy

• Study of the universe beyond Earth's atmosphere
• Branches:
  • Astrophysics: study of physical properties of celestial objects
  • Planetary science: study of planets and their moons
  • Cosmology: study of the origin and evolution of the universe
• Key concepts:
  • Stars: massive balls of hot, glowing gas
  • Galaxies: massive collections of stars and other celestial objects
  • Planets: large celestial bodies orbiting stars
  • Black holes: regions of intense gravity

Chemistry

• Study of the properties, composition, and reactions of matter
• Branches:
  • Organic chemistry: study of carbon-containing compounds
  • Inorganic chemistry: study of non-carbon-containing compounds
  • Physical chemistry: study of chemical reactions and processes
  • Biochemistry: study of chemical processes in living organisms
• Key concepts:
  • Atoms: building blocks of matter
  • Molecules: groups of atoms bonded together
  • Chemical reactions: transformations of substances
  • Periodic table: organized table of elements

Physics

• Study of the natural world around us
• Branches:
  • Mechanics: study of motion and forces
  • Thermodynamics: study of heat and energy
  • Electromagnetism: study of electricity and magnetism
  • Quantum mechanics: study of behavior at the atomic and subatomic level
• Key concepts:
  • Energy: ability to do work
  • Matter: anything that has mass and takes up space
  • Space: three-dimensional expanse that makes up the universe
  • Time: measurement of duration and sequence of events

Biology

• Biology is the study of living organisms and their interactions with each other and the environment
• It has several branches, including:
  • Botany, which studies plants
  • Zoology, which studies animals
  • Microbiology, which studies microorganisms
  • Ecology, which studies the relationships between organisms and their environment
• Key biological concepts include:
  • Cells, which are the basic units of life
  • DNA, which is the genetic material that contains the instructions for an organism's development and function
  • Evolution, which is the change in species over time
  • Ecosystems, which are communities of living and non-living components that interact with each other

Geology
