Study Notes
The Universe
- Earth is approximately 4.5 billion years old; the universe is about 13.8 billion years old.
- Various religious cosmologies provide different narratives for the origin of the universe, starting from Genesis in the Bible.
Religious Views on Creation
- Mormonism: Believes in pre-existing life, not created ex nihilo. Proposes a plan of salvation for human progression, allowing advancement like God.
- Buddhism: Emphasizes karma and the interconnectedness of beings and the universe. Concept of creation is inconceivable and has no definite beginning or end.
- Islam: Claims God created the universe and humanity, encouraging meditation on the cosmos.
- Hinduism: Views creation as timeless, involving cycles of creation and destruction without a distinct beginning.
Scientific Theories of Creation
- Steady State Theory: Proposes a continuously expanding universe that maintains constant density; theorists include Fred Hoyle, Thomas Gold, and Hermann Bondi.
- Big Bang Theory: Currently the most accepted theory; posits that universe expanded from a singularity approximately 14 billion years ago. Key concepts include inflation, red shift (moving away), and blue shift (moving towards).
- Oscillating Universe: Suggests a perpetual cycle of big bang and big crunch, theorized by Richard Tolman.
- Multiverse Theory: Suggests our universe is one of many, or "bubbles," theorized by Hugh Everett III.
The Solar System
- Encounter Hypothesis: Suggests that a rogue star interacted with the sun about 5 billion years ago, influencing gas formation into planets. The outer planets formed from denser material and inner planets from lighter sun materials.
- Nebular Hypothesis: Proposes that the solar system formed from a gas cloud that collapsed due to its gravity, resulting in the sun and planets approximately 4.5 billion years ago.
- Protoplanet Hypothesis: Extends the nebular hypothesis, indicating planets formed from accumulated gas and dust in a collapsing interstellar cloud.
Earth and its Subsystems
- Earth consists of interrelated physical, chemical, and biological processes that form four main subsystems: geosphere, atmosphere, hydrosphere, and biosphere.
Atmosphere
- Described as a protective blanket around the Earth composed of gases like oxygen, carbon dioxide, argon, nitrogen, and water vapor.
- Composition of Air: 99% is oxygen and nitrogen; the remaining 1% includes argon, carbon dioxide, and helium.
Layers of the Atmosphere
- Troposphere: Closest to the surface; where weather occurs and where planes operate safely.
- Stratosphere: Contains ozone for UV protection; location of jet planes and radiosondes.
- Mesosphere: Coldest layer where meteors burn up, causing shooting stars.
- Thermosphere: Contains individual gas molecules; home to auroras and is the hottest layer.
- Exosphere: Extends into space; where satellites orbit.
Hydrosphere
- Encompasses all water on Earth, accounting for 75% of the planet's surface; saltwater makes up 97% while freshwater constitutes 3%.
- Freshwater sources include glaciers, rivers, and lakes, with a significant portion trapped in ice.
Geosphere
- Represents the solid part of Earth, consisting of rocks, minerals, and landforms, which provide essential nutrients for plants through the rock cycle.
- Composed of distinct layers: crust (solid), mantle (solid), and the core, which includes inner and outer layers.
