  • “Story of Creation”

  • “Brahmanda”

Ancient Theories of the origin of the universe

4
New cards

The Big Bang Theory

  • supporters of this theory believes that the universe started at a single compact point where matter and energy is the same as each other.

  • This dense point of energy and matter then blasted or expanded in a millionth of a second releasing matter and energy that seconds or possibly years later developed into our universe.

5
New cards

Red Shift

  • One of evidences of the Big Bang Theory is the expansion of the universe observed through the movement of the celestial objects relative to a reference point known as the Doppler Effect.

  • As the stars move, astronomers observe a light with increasing wavelengths towards the red end of the visible spectrum. This is known as the Red shift indicating that the stars are moving away from the point of observation.

6
New cards

Hubble’s Law

A part of the red shift theory that states “The bigger the red shift the farther or more distant the object”

7
New cards

An Expanding Universe

Astronomers attributed the expansion to the the big bang. A good analogy of this is a raisin cake where in as the cake cooks and expands the raisins become farther apart.

8
New cards

Steady State Theory

  • This theory states that stars and galaxies may change but the universe will always look the same. This is possible with the formation of new matter in between the open spaces between the stars.

  • • A flaw in this theory is that if matter is continuously created then stars in a specific area should be of the same age which is not the case

9
New cards
  • Big Crunch Theory

  • Big Chill Theory

Theories of the end of the universe

10
New cards

Big Crunch Theory

Theory of the end of the universe that states that There will be a certain point after the big bang where matter and energy will become one which will cause the destruction of every planet, galaxy and other heavenly bodies

11
New cards

Big Chill Theory

Theory of the end of the universe that states that With not enough mass the universe will keep on expanding which will cause a drop in temperature creating an atmosphere of cold and chill

  • Core Accretion Model

  • Pebble Accretion

  • Disk Instability Model

LIST OF FORMATION MODELS

13
New cards

Core Accretion Model

FORMATION MODEL

  • The most accepted model but has problem explaining the formation of gaseous planets

  • The Solar System started as a cloud of dust and gas known as a solar nebula. Gravity caused the materials inside the nebula to spin forming the Sun at the center, meanwhile the smaller particles clustered together and formed the planets.

  • Solar winds removed the lighter materials such as helium and hydrogen causing the planets closer to the sun to be rocky while those father from the sun where the solar winds has lesser impact became the gas giants

14
New cards

Disk Instability Model

FORMATION MODEL

  • The problem with the core accretion model is that the formation of the gas giant will take longer than the time that the lighter gas will be obtainable as

  • This problem is answered by the disk instability model where in it is stated that giant planets formed early in the formation of the solar system, a process that sometimes took as little as 1000 years.

  • Due to the faster formation of the planets, they were able to trap lighter gases before they vanish, they will then reach an orbit stabilizing mass preventing them to deathmarch into the sun.

15
New cards

Pebble Accretion

FORMATION MODEL

  • Another point of contention in the core accretion model is the time it took to form the planets; thus, the pebble accretion model was formulated.

  • This model explains how tiny pebbles formed the planets we knew today. It stated that larger objects acts like a bully and pebbles from medium sized objects thus they grow at a faster rate.

EARTH'S SUBSYSTEM

  • Refers to the Earth’s rocks, minerals, & geologic landforms

  • Also known as the Lithosphere, it is consisting of the Earth’s inner structure which include the crust and upper mantle

  • The geological processes that occur above and below the ground shapes and changes the geosphere

18
New cards

Atmosphere

19
New cards

Hydrosphere

EARTH'S SUBSYSTEM

  • Consists of oceans, lakes, rivers, and all bodies of water as well as the water vapor that condenses to form clouds.

  • The atmosphere directly affects the hydrosphere, an example of which is how the ocean’s temperature changes as the air temperature change which can lead to the formation of storms

20
New cards

cryosphere

EARTH'S SUBSYSTEM

  • Considered as a subcomponent of the hydrosphere

  • Consists of water in solid form such as glaciers, snow, ice in the ocean, permafrost, and frozen ground.

  • The cryosphere is directly affected by the Earth’s temperature, warmer temperature may cause the ice to melt thus increasing sea levels. Less ice will also lead to warmer temperature since naturally occurring ice reflects sunlight

21
New cards

Biosphere

EARTH'S SUBSYSTEM

  • This subsystem is a global ecosystem composed of biotic and abiotic components.

  • In its early days, the Earth is a desolate place composed of the geosphere, hydrosphere and the atmosphere. As the Sun bombarded the planet with energy tim3 went by life begun to form on Earth through physical and chemical actions.

  • Thus, the thin layer of the geosphere where life thrived was called as the biosphere of the “zone of life”

22
