|
Cosmology |
Is the branch of science that studies the origin, evolution and fate |
|
|
|
First theory/big bang theory |
In this theory, energy and matter divided and became distinct from each other. After that massive explosion, dust and portion of the condensed matter and energy started to spread out. These scattered particles eventually congulated and different objects and heavenly bodies began to form. Moon, stars, solar system, and galaxies were formed |
Theory |
|
|
Second theory/steady state theory/ infinite universe theory |
The density of matter in the expanding universe remains unchanged due to continues creation of matter, thus adhering the perfect cosmological principle. This principle asserts that the observation universe is basically the same at any time as well as at any place |
Theory |
|
|
Solar system |
The gravitionally bound system comprising the sun and the objects that orbit it. It is in constant motion, with the planets and their moons, comets, asteroids, and other space objects revolving around the sun. |
|
|
|
Earth's crust |
Earth's solid exterior , which is composed of a great variety of rock types that respond in diverse ways and at varying rate to surface process. the only portion of the lithosphere of which earth scientist have direct knowledge, yet it represents only about 1% of Earth's planetary mass |
Earth |
|
|
Oceanic crust Continental crust |
2 types of crust Is very thin but dense Is thick but less dense |
|
|
|
Oxygen(O)46.60 Silicon(Si)27.60 Aluminum (Al)8.13 Iron(Fe)5.00 Calcium(Ca)3.63 Sodium(Na)2.83 Potassium (K)2.70 Magnesium (Mg)2.09 |
Most common elements in Earth's crust |
|
|
|
Upper mantle |
Extends from the crust to a depth of about 670 kilometers below the Earth's surface. It is mostly solid and it is malteable regions contribute to tectonic activities |
Earth |
|
|
Lower mantle |
Extends from 660 kilometers UpTo 2700 kilometers below the Earth's surface. It's temperature is about 3000 degree C. which makes it much hotter and denser that the upper mantle. It is mostly solid rocks, and composed of the elements iron, oxygen, magnesium, and aluminum. |
Earth |
|
|
Outer core |
The second largest layer and second to the last layer of our planet. It is about 2,200 kilometersrhick and is composed entirely of super-heated liquid iron and nickel. NiFe alloy of the outer core has is extremely hot and it's temperature range between 4,000 to 5,000 Celsius |
Earth |
|
|
Inner core |
Is exceedingly hot, dense huge metal mostly iron 2,500 km wide. The temperature of the it rangest from 5,000 to 6000 celcius which is enough to make metal melt |
Earth |
|
|
Geosphere |
Makes up the solid portion of the earth, it's structure and land. The planets inner core which extends to the crust is predominantly classified as the lithosphere; the upper mantle and the crust. The lithosphere is the area that mostly affects the Earth's systems. |
Earth's system |
|
|
Ground |
Geosphere include the nonliving land features. Geosphere came from latin term "Geo" which means |
|
|
|
Lithosphere |
Is the rocky outer part of the earth. It is made up of the brittle crust and the top part of the upper mantle. Is the coolest and the most rigid part of the earth.
|
Earth's system |
|
|
Asthenosphere |
Greek: anthenias, without strength Beneath the lithosphere |
Earth's system |
|
|
Hydrosphere |
This covers about 75% of the Earth's surface, including ground water and Earth's frozen water (the cryosphere) and almost of the water is 1% drinkable |
