Earth and Life Science

• Universe - Carries all celestial body including matter and energy and under milky way galaxy
• Galileo Galilei - is the person whom blinded because he attempt to see the sun
• Big-Bang - Starts out of nothing then it expands; starts from explosion and expansion that came from hot dense material.
• Steady State - the universe is constantly expanding but the same mass/density
• Oscillating Theory - the universe is continuously expanding and contracting; it is a cycle of big-bang crunch.
• Nebular Theory - The universe came from class of cloud/dust
• Planetisimal Theory - the universe came from a collision of the planets/ two planets
• Stellar Theory - our universe created because of the collision of two stars/stars
• Goldilocks Zone - it is a right distance from the sun in the right temperatures for water to remain liquid. It is also known as Habitable Zone
• Atmosphere - it is a mixture of gases around earth where it protects life beneath of it by shielding the incoming Ultraviolet (UV). It has 78% "Nitrogen", 21% "Oxygen", 1 "Trace".

• Biosphere is an environment that contains all "living organism" and the products of their activities. Plays an important in conserving ecosystem.

• Biosphere has 5 living things it is; 1. Plants, 2. Human/Animals, 3. Bacteria, 4. Fungi, and 5. Protist
• Hydrosphere - total amount of water that the earth has; 71%
• Lithosphere/Geosphere - amount of land that the earth has. 29% of land
• Crust - it is the outermost shell of the planet earth, where it can be livable and where the people live in. The thick or distance of it was 8-40km
• Crust - has 5 elements it is Magnesium (Mg),Iron (Fe), Oxygen (O), Aluminum (AI),Silicon (Si) and it is solid
• Crust - has 5 elements it is Magnesium (Mg),Iron (Fe), Oxygen (O), Aluminum (AI),Silicon (Si) and it is solid
• Mantle is the semi-solid rock and it is hot; where the magma began to create. It is 2,900km thick
• Outer Core is a fluid thick layer and it is very dense and hot and 2.250 km thick/deep and composed of Iron(Fe),Nickel (Ni) and Sulfur (S).

• Mantle is composed of Magnesium (Mg), Iron (Fe), oxygen (o), Aluminum (Al), and silicon (Si)
• Inner Core is the innermost layer of the earth. It is made of Iron (Fe) and Nickel (Ni) and has a thick layer of 1,300km
