Study Notes

Cosmology and Meteorology

Cosmology studies the universe in its entirety, attempting to explain its origins, evolution, and eventual fate.
Meteorology focuses on the Earth's atmosphere, specifically weather events and conditions that influence the climate.

Solar System Features

Sun:
- Sunspots are cooler areas on the solar surface, associated with strong magnetic activity.
- Solar prominences involve plasma loops connecting sunspots.
- Solar flares and coronal mass ejections release energetic particles, affecting solar and earthly phenomena.
Mars:
- Identified as the fourth planet and known as the "Red Planet."
- A day on Mars lasts slightly over 24 hours, with two moons: Phobos and Deimos.
Jupiter:
- Largest planet in the solar system with the shortest rotational period, completing a rotation in approximately 10 hours.
- Possesses 80 moons; the Great Red Spot is a massive storm.
- Voyager mission revealed Jupiter's faint ring system; currently explored by NASA's Juno orbiter.
- Europa is considered one of the most promising locations for the potential of extraterrestrial life.
Saturn:
- Sixth planet, distinguished by its 83 moons and prominent seven-ring system.
Uranus:
- Seventh planet, first identified with a telescope by William Herschel.
- Has 27 known moons and 13 known rings.
Neptune:
- Eighth planet, with 14 known moons and five main rings.
- Notable for being the first planet discovered using mathematical calculations.

Types of Planets

Terrestrial Planets: Include Mercury, Venus, Earth, and Mars, characterized by rocky surfaces.
Jovian/Gas Planets: Comprise Jupiter, Saturn, Uranus, and Neptune; these are gas giants with thick atmospheres.

Earth's Subsystems

Atmosphere:
- A gas mixture enveloping Earth, crucial for sustaining life.
- Volcanic eruptions can significantly affect air quality and climate.
- Inner Earth dynamics are minimally influenced by human actions.
- Increased ocean acidity disrupts marine ecosystems, impacting the overall Earth system.
- Methane release from melting permafrost may accelerate global warming.
Types of Rocks:
- Classified into igneous, sedimentary, and metamorphic based on formation processes.
MOHS Hardness Scale:
- A standardized scale for measuring mineral hardness.

Mineral Properties

Hardness:
- Ability of a mineral to resist scratches, fundamental in identification.
Luster:
- Describes how a mineral reflects light, varying in appearance based on composition.
Color:
- One of the most apparent properties, yet it can fluctuate based on surface conditions.
Streak:
- The color observed when a mineral is powdered, used for identification.
Specific Gravity:
- The ratio of a mineral's mass to the mass of an equal volume of water, reflecting density.
Cleavage:
- A mineral's capacity to break along defined planes, affecting its structure.
Fracture:
- Refers to how a mineral breaks irregularly, showcasing its internal structure.
Tenacity:
- Describes a mineral's resistance to breakage or deformation.
