Study Notes
Astronomy and Space
- An astronomer is a scientist who specializes in the study of celestial bodies such as stars, planets, and other phenomena in space.
- The planet Pluto was classified as the ninth planet from its discovery in 1930 until its reclassification in 2006 as a dwarf planet due to new definitions of what constitutes a planet.
Earth Science Concepts
- The term axis refers to an imaginary line around which celestial and terrestrial objects, including planets, rotate. Earth's axis is tilted, which contributes to seasonal changes.
- Seasons are natural divisions of the year, categorized into four key periods: summer, winter, fall, and spring, each characterized by distinct weather conditions and daylight variations.
Physical Changes and Tools
- Sublimation describes the process where a substance transitions from solid to gas without passing through the liquid state, such as ice transforming directly into water vapor.
- A telescope is a crucial tool in astronomy that allows observers to see distant objects more clearly by magnifying their appearance, making it essential for studying celestial bodies.
