graphing points.

Hi,
today we are going to talk about how to graph points.Graphing points is realy easy and it dosent require anything but a graph and coradnits.cordinates look like this-(2,3)-They can be ether nege.itive or positive but let us stick with the positive.The graph looks like this.The graph could go forever.

Let us plot something.let us take the one that I used as an example.(2,3).So we always then up.So we go 2 across and then 3 up. There is our point.That is realy it so thank you.

rock cycle.

Hi,
Today we are going to talk about the rock cycle. The rock cycle is the process that witch the rocks go through.This a picture of it.As you can see there is many ways that rocks can go.It is an endless circle.


I will explain it.Lets start at metamorphic.It can ether be melted or be turned into sediment.Sediment then squeezes together and becomes sedimentary.It then goes through heat or erosion.Once heated it turns back to metamorphic.And so on.

stand off

Hi,
today we are battle pemdas vs. percent.This is the very time to decide witch is better.Nobody would ever know that this would ever happen.But fate has broght us to this momunt.

PEMDAS
The advantages are that pemdas is a thing that you know what to do first, and it is an algorithm.P=parenthies,      E=exponents, M or D=multiplcation and divtion, A or S=Adding and subtracting.The disadvanteges are that it is confusing and it can sometimes be super long.

Percent
The advanteges of  percent are that there are magic numbers that can be very helpfull like 2,4,5,10,20,25,50,100,9 and 99.If it is any of these numbers then it would be very easy, like 1/2 would be 50% and so on.The disadventeges are that it is very hard to find the percent of a number if it is not 100.

Poll
Now vote on the side bar.Vote, vote, VOTE,vote,VOTE!!!!Please.

constallations

Hi,
today we are going to talk about constalations.They are pictures that are made by stars.The most common ones are the big dipper and Orion..Their names are usaly  Greek.They can either be an animal or person.Some constalitions are only seen in a single season and some are seen every season.sinse 1922 88 constalations are named and seen.

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.

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.

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.
