Study Notes
Natural Sciences
- The study of our physical world through experimentation.
- Divided into Physical Sciences and Life Sciences.
Physical Sciences
- Study of non-living components of the natural world.
- Divided into:
Physics
- Studies:
- Motion: How things move and the forces that influence them.
- Energy: Different forms and conversions.
- Heat: The transfer and effects of thermal energy.
- Sound: How sound is created and transmitted.
- Light: Properties and behavior of light.
- Electricity and Magnetism: The relationship between these forces.
Chemistry
- Studies:
- The structure, composition, and properties of matter.
- Chemical reactions and transformations.
Earth Sciences
- Studies:
- The Earth's structure, composition, and processes.
- Subdivided into:
- Geology: Rocks, minerals, and the Earth's solid surface (lithosphere).
- Hydrology: Water, bodies of water, and water cycles (hydrosphere).
- Meteorology: The Earth's atmosphere and weather patterns.
Space Science
- Studies:
- Celestial bodies (Planets, stars, galaxies).
- Space phenomena (Black holes, supernovae).
- Studies:
The Scientific Method
- A systematic approach to investigation and discovery.
- Involves:
- Observation and question formation.
- Hypothesis development.
- Experimentation and data collection.
- Analysis and interpretation of results.
- Conclusion and communication.
Solar and Stellar Energy
- Thermonuclear fusion is the energy source of the sun and stars.
Space Rocks
- Asteroids: Rocky bodies orbiting the Sun, primarily found in the asteroid belt.
- Meteors: A streak of light produced when a meteoroid enters the Earth's atmosphere and combusts.
- Meteoroids: Small rocky or metallic body in space.
- Meteorites: A meteoroid that survives passage through the Earth's atmosphere and hits the surface.
The Atmosphere
- Functions:
- Supports Life: Provides essential gases like oxygen and carbon dioxide.
- Absorbs Solar Radiation: Regulates the Earth's temperature.
- Burns Up Meteors: Protects the Earth from harmful space debris.
Water Resources
- Groundwater: Water stored beneath the Earth's surface, primarily located in aquifers.
- Aquifer: A layer of rock or sediment that can hold and transmit groundwater.
- Spring: A natural discharge point of groundwater.
Ocean Zones
-
Pelagic Zone: The open sea, subdivided into:
- Neritic Zone: Shallow water near the coastline.
- Oceanic Zone: Deeper water extending up to 600 feet.
- Benthic Zone: The ocean floor.
Benthic Zone
- The ocean bottom, with different regions based on depth:
- Epipelagic/Euphotic Zone: Surface layer where sunlight supports photosynthesis.
- Mesopelagic/Disphotic Zone: Dimmer zone with limited sunlight.
- Bathypelagic/Aphotic Zone: Deepest zone with no sunlight.
Tectonic Plates
- Large sections of the Earth's lithosphere that move over the asthenosphere (molten layer).
- Interactions of different tectonic plates:
- Convergent Plates: Plates collide, leading to mountain formation, volcanoes, and earthquakes.
- Divergent Plates: Plates move apart, creating new ocean floor and rift valleys.
- Transform Plates: Plates slide past each other, causing earthquakes.
Volcanoes
- Vents or openings on the Earth's surface where magma and volcanic materials escape.
- Magma: Molten rock beneath the Earth's surface.
- Lava: Magma erupted onto the Earth's surface.
- Pyroclastic Flow: A fast-moving, hot mixture of volcanic debris and gas.
- Tephra: Volcanic fragments ejected into the air.
-
Types of Volcanoes:
- Cinder Cone Volcano: Cone-shaped volcano formed by ejected lava fragments.
- Composite Volcano: Steep-sided cone composed of alternating layers of lava and ash.
- Shield Volcano: Broad, low-lying volcano formed by effusive lava eruptions.
Periodic Table of Elements
- Elements are organized according to:
- Increasing Atomic Number: The number of protons in the atom's nucleus.
-
Major Groups:
- Group IA (Alkali Metals): Highly reactive metals.
- Group IIA (Alkaline Earth Metals): Reactive metals.
- Group VIIA (Halogens): Nonmetals.
- Group VIIIA (Noble Gases): Unreactive gases.
- Transition Metals: Metals with variable oxidation states and diverse properties.
Properties of Metals
- Malleability: Ability to be hammered or pressed into shapes without breaking.
- Ductility: Ability to be stretched into thin wires.
- Luster: Shiny appearance.
- Conductivity: Ability to conduct heat and electricity.
