Study Notes
Creation and Origin of the Universe
- Creation Myth refers to a culture's symbolic narrative describing the universe's beginnings.
- Big Bang theory posits that the universe began approximately 14 billion years ago.
- Red Shift Theory, which explains the universe's expansion, was proposed by Edwin Hubble.
- Cosmic Microwave Background radiation signifies the remnant energy from the Big Bang explosion.
- Steady State Theory claims the universe is unchanging over time and uniform in space.
Earth and Its Composition
- Nitrogen is the primary component of the Earth's atmosphere, making up around 78%.
- The lithosphere is the outermost layer of Earth composed of solid rock.
- Ozone layer in the stratosphere primarily absorbs harmful ultraviolet rays from the sun.
Theoretical Models of Formation
- Nebular Theory describes the solar system's formation from a collapsing cloud of gas and dust, resulting in circular orbits due to whirlpool-like motions.
- The Nebular Theory supports that planets formed from a giant molecular cloud.
Terrestrial and Non-Terrestrial Planets
- Jupiter is classified as a gas giant, thus not a terrestrial planet, which includes Earth and Mars.
Earth's Surface and Atmosphere
- Approximately 70% of Earth's surface is covered by oceans.
- The stratosphere is the atmospheric layer that absorbs ultraviolet radiation.
Earth's Inner Structure
- Lithosphere rests on the softer asthenosphere beneath it.
- Upper Mantle layer exists from the Earth's crust down to about 410 kilometers depth.
- Outer Core, predominantly liquid iron and nickel, lies beneath the mantle.
- Inner Core is the deepest part of the Earth, composed of solid iron and nickel.
Domains of Life
- Archaea, Eukarya, and Bacteria are the three domains of organisms; Archaea and Bacteria are single-celled.
True/False Statements
- The Nebular Theory asserts the solar system formed from gas and dust – True.
- Geocentrism positions Earth at the solar system's center – True.
- The atmosphere is primarily composed of oxygen – False, it's mainly nitrogen.
- The Cryosphere encompasses all frozen water forms on Earth – True.
- The biosphere includes both land-dwelling and aquatic organisms – False, it contains all ecosystems.
