plate tectoics

Hi today we are going to talk about plate tectonics.plate tectonics is the theory that the earth is broken up into sections. The earth is broken up into 16 plates.Every year they move 1-12 cm.Each plate is ether a Continental plate and oceanic plate.The biggest plate is the pacific plate.The smallest is the Juan De fuca.

The plates move in three different ways.Convergent or to come together, divergent or to go opposite directions, and transform or slide past each other.When they move 3 things can happen.Either a mountain,trench, or earthquake.Most happen around the pacific plate.

mineral #4

Hi,
Today is the last day for single minerals.Today we will talk about the satounding sapphire.A sapphire is on the hardness scale at a level of  9.They are mostly every color but red.It's formula is AL2O3.It's streak is white.It's luster is Vitreous.It's melting point is 2030 c.

It was believed that the earth was resting on a sapphire.Out of all the colors of a sapphire blue is the best.The others are consiterd as fancy colors.A sapphire reprasents truth and faithfullness.It is the most scarsed gemstone.It was believed to have healing powers.It i the birth stone of septomber.

mineral 3

Hi,
Today we will be talking about diamonds.A diamond is the hardest mineral in the moths hardness scale.It has a straengh of 10.Diamonds can typically be yellow, brown to gray or coloress.It's formula is C.It has a coloress streak.It's luster is Adimintine.It's melting point is preassure dependent.

Diamonds are the status of love.They are the symbol of love like rubys.There are also used in wedding rings.There are also the to find conflict in afrcia..Because the diamond is the hardest mineral .It is sometimes used in drills.It is one of the 12 god minerals.

Minerals#2

Hi,

For the next few posts we will talk about a certain mineral.In this post we will talk about the mineral,ruby.A ruby is the second hardest mineral right before diamonds.Rubies can be red, purplish,pinkish, or brown.It's formula is AL2O3:Cr.It's streak is white.It's luster is Vitreous.It's melting point is at a wapking 2044oC

It is said that a ruby has a fire in it that never goes out.This makes it the symbol of love.That is why it makes a great ring.If worn on the left hand it will bring you happiness and joy.Some say it is the best of the 12 stones that were created by god.It is also said that if it changes color it means danger.Rubies are very similar to sapphires.They say the ruby is the king of gems.This jewel is most commonly used in rings and bracelets.

minerals

Hi,
Today we are going to talk about minerals. The important characteristics of a mineral are being in the solid form, naturally occurring, definite chemical composition, inorganic, and having a crystal structure. Coal is not a mineral because it is missing  three of these characteristics. There are a bunch of tests you can do to find out facts about minerals such as streak, luster, color, scratch and fracture. Now lets talk more about mineral formation in nature. Minerals can take about 1000 years to be a inch tall grown. Some examples of minerals are rubies, diamonds, sapphires, onix, and emerald.
Each mineral stone has a place on the moths hardness scale. Diamond would be the highest at 10 because it is the strongest mineral ever found.The biggest diamond is a 432 carats diamond.Talc, on the other hand is on the moths scale at the lowest level 1. It can be easily scratched with a finger nail. All other minerals stays in between on the hardness scale. There is no level above ten but there is hardness values like 3.4, 9.9 and so on. Minerals can be worth more than  $10,000.We will talk a little more on our next post.

Periodic Table of elemints.

Hi,
Today we are going to talk about the Periodic Table of elements. The Periodic Table of elements is a table where are the elements are listed in certain rows and columns. There are 112 elements on it. The father of the periodic table is Dmitri Mendeleev. He created the first in 1871. In the modern table, the elements are organized in the increasing order atomic number. The atomic number is the number of protons in a atom of the element. All elements are made up of the smallest particles called atoms. Each atom is made up of three fundamental particles such as electrons, protons, and neutrons. The vertical columns are called groups or families and the horizontal rows are called periods.
Each element has a symbol witch could have 1-2 letters. This symbol is given in the table. In addition to the chemical symbol, atomic number, atomic mass, physical state of each element, group numbers, and electron arangement are also given. The elements are classified into mainly 4 classes such as noble gasses, main group elements, transition metals and inner transition metals.
Here is a link to a table.http://www.popsci.com/files/periodic_popup.html
