Earth and Science Flashcards
The three Origin of the Universe
- Big Bang Theory
- Steady State Theory
- Pulsating Theory
Who is the father of the Big Bang Theory?
George Lemaitre
He was an early advocate and developer of Lemaître’s Big Bang theory.
(Universe Expansion)
George Gamow
Earth is assumed to be at the center of it all.
Geocentric Model
The planet Earth was the center of the universe and all of the other planets, stars, and the Sun revolved, or circled, around it.
Ptolemaic Model
Earth and Planets revolve around the Sun.
Heliocentric Model
He created the theory of Heliocentric which means, Earth and Planets revolve around the Sun.
Nicolaus Copernicus
He made accurate observations of the stars and planets.
Tycho Brahe
He discovered that the earth and planets travel about the sun in elliptical motion.
Johannes Kepler
He gave 3 fundamental laws of planetary motion. (Law of Motion)
Johannes Kepler
It formed about 380,000 years after the Big Bang and imprinted on it are -traces of the seeds- from which the stars and galaxies we can see today eventually formed.
Cosmic Microwave Background (CMB)
The 5 Celestial Bodies
- Stars
- Planets
- Comets
- Meteoroids
- Satellite
Collapse under the force of gravity. (Dust, Clouds)
Nebula Clouds
Dust and Gasses
Nebula
A system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.
Galaxy
Located in the Milky Way Galaxy
The collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets. The planets of the solar system are (in order of distance from the sun) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
Solar System
From the Origin of Universe:
Cyclic Event (the universe goes through regular cycles of expansion and destruction.)
Continues expansion and contraction in universe.
Pulsating Theory
Is an all space-time, matter and energy including the solar system, all stars and galaxies and content of intergalactic space, regarded as a whole.
Universe
From the Origin of Universe:
Continues expansion and contraction in universe.
Pulsating Theory
From the Origin of Universe:
Explode and expand again
Pulsating theory
Origin of the Universe:
It states that the counting of the galaxies in our universe is constant and new galaxies which are forming continuously are filling the empty spaces which are created by those heavenly bodies which have crossed the boundary lines of observable Universe.
Steady State Theory
Origin of the Universe:
This theory proposes that the overall structure of the universe is always the same at any point in time and space. This structure is maintained even when certain events, such as birth of new stars, occur. It is balanced by the death of old stars.
Steady State Theory
Origin of the Universe:
It proposes that the entire universe was once condensed in a very small and compact particle called primeval nucleus.
Big Bang Theory
Origin of the Universe:
It is estimated about 20 billion years ago, primeval Nucleus suddenly exploded in a big bang.
The force of this explosion caused matter to scatter in any direction forming a universe.
Big Bang Theory
_____________ suddenly exploded in a big bang
primeval nucleus
“In the beginning God created the heavens and the earth.”
Genesis 1:1
Need to Memorize:
Primeval Nucleus -> Cosmic Microwave Background -> Cosmic Egg -> Galaxy -> Solar System
->planetesimal, Protoplanet, Proto Sun -> Nebula Clouds -> Celestial Bodies

What are the 2 models of the solar system?
- Geocentric Model
- Heliocentric Model
(From Big Bang Theory)
It believed that the “age of the universe”—is
13.7 or 13.8 billion years

This Galaxy where our Solar System is Located
Milky Way
The Earth Four Subsystems
- Hydrosphere
- Geosphere
- Atmosphere
- Biosphere
living things within an ecosystem, such as plants, animals, and bacteria
Biotic
non-living components, such as water, soil and atmosphere.
Abiotic
What is “O” in Ozone Layer
Oxygen
How many percent are in Saltwater?
67%
How many percent is the Fresh water?
3%
Where can we find the ozone layer?
Stratosphere
What is Organic?
Living
What is Microorganism?
Bacteria
Solid part of the Earth
Geosphere
The Blue planet/ Water planet that part of our Earth Subsystem.
Hydrosphere
The layers of gases surrounding planet earth.
Atmosphere
Which does not belong?
a.Big Bang Theory C. Oscillating Theory
b. Solar Nebular Theory D. Steady state Theory
B.
CMB means?
Cosmic Microwave Background
In what layer of the atmosphere, many satellites orbit?
Exosphere
What is the largest part of the earth?
Hydrosphere
Who discover the phenomenon of Expansion?
Edwin Hubble
In the troposphere, as the altitude rise, what happen to the temperature?
Decreases
What is the importance of magnetic field?
It protects us from harmful UV rays.
2 Kinds of Crust
- Continental Crust
- Oceanic Crust
Part of the earth that life exist.
Biosphere
It forms from the cooling of melted rock (either lava or magma into solid form.
Igneous rocks
Form when existing rocks are subjective to intense heat and pressure, usually deep below the earth’s surface.
Metamorphic rocks
These conditions change the original minerals of the rock into new minerals.
Metamorphic rocks
Are either detrital or chemical.
Sedimentary rocks
formed by the compaction of separate particles, or sediments, into a rock.
Detrital rocks
Form from minerals that have been dissolved in water and precipitate out, forming a solid rock.
Chemical sediment rocks
Used by geologists to identify carbonate minerals.
Acid Test
It is the dense center and hottest part of earth.
Core
made almost entirely of iron and nickel.
Core
It is the mostly solid bulk of Earth’s interior.
Mantle
mostly composed of different types of granites. Geologists often refer to the rocks of the continental crust as “sial” which stands for silicate and aluminum, the most abundant minerals
Continental Crust
mostly composed of different types of basalts
Oceanic Crust
the outermost part of the earth and is very thin compared to the other layers. It is a part where the living organisms dwell in. It forms a very thin continuous layer that extends underneath the ocean and continents.
Crust
a naturally occurring solid aggregate of one or more minerals.
Rocks or Stone
Three major types of rocks
- Igneous Rocks
- Metamorphic Rocks
- Sedimentary Rocks
6 Layers of Earth Atmosphere:
- Exosphere
- Thermosphere
- Ionosphere
- Mesosphere
- Stratosphere
- Troposphere
