Changes in Earth's rotation or revolution

     The Earth changing earthquake's tsunami shifted coastlines and elevation, it caused Earth's rotation to speed up. It occurred when a section of the tectonic plate lying under the Indian Ocean shifted some 15 meters toward Indonesia, sliding further underneath an adjoining plate and caused it to spring forward. Some of the planets mass was drawn closer to the planets center. The day had been shortened by about 2.6 microseconds, or millionths of a second. The Earth's wobble would increase by about an inch as result from the earthquake.

     Neptune's southern hemisphere have been growing bigger and brighter in recent decades. Neptune's southern hemisphere is receiving more solar radiation then the northern hemisphere. Solar heating of the planet's atmosphere can cause convection currents, or the rising and falling of air.

The Big Bang Theory

The Big Bang Theory explains what happened when our universe began and to explain what happend durring and after that moment. Our universe began 13.7 billion years ago. Edwin Hubble invented this theory. Edwin Hubble discovered The Big Bang Theory in 1929.
Most scientists are certain that the universe had a beginning. Galaxies appear to be moving away from and there speed is disproportional to there distance. the observation supports the expansion of the universe and that is was once compacted. If the universe was very hot we should be able to find remnant of this heat.

My favorite thing in science is life science. Life science is cool beause you learn about a lot of the living things on earth and a lot about humans and how we work. Studying life science is a good thing to study so you know how all things on this planet that have beating hearts work and where they live and what they eat. Studying about how our insides work is really interesting and good to know so if something happens you can tell what it is and if someone else gets hurt you can tell them what happend to them. There is a lot to know in life science. In life science studying about how our system works you learn about what bad food does to you like eating cheese cake and saturated fat cloggs up your arteries and when you don't drink water the cells in ur body die because they don't have enough nutrients to live. You will learn about all the parts of the body on a male and female and how those parts work. Parts of the body are a lot to remember and the parts are differant from both a male and female.

The most important rule in science i think is not to do anything before the tacher tells you to.

Why is it important?

I think it is important because if kids start to mess with the stuff the teacher has laid out on the table they could either break something and get cut, get burned by acid, or get dangerous chemicals in there eyes. Kids could get hurt very bad and thats why i think this rule is important.

What would happen if the rule isn't followed?

If the rule isn't follwed kids could get bad chemicals in there eyes, ged burned by acid or fire, and either break something that is glass and cut themselves reall bad.

What rule is most useless?

Do not play with fire or a burning thing.

Why is it useless?

Well i'm sure that everyone in middle school knows not to play with the burner or fire and matches you must need to go back to elementry school and get that tought to you again.

Describe when the most useless rule would apply?

When this would apply is when you are doing an expeirement when you are using the burner and you would have common sense to not touch the burner because i would think noone would do that.

Earth science is important to know because we need to know how it works and study its past and the changes that has occured to today. Geoscientist study earth and how it works they also study space and its relation to earth. Its thin layer of air, its solid, its water, an it deep inside. Geoscientist put sensores in the ground to measure earths movement and they send it all over the world to other geoscientist. Earth science is all about change over time from about 4.6 billion years ago through all the ages of geological time. when studying earth science you can learn about the forces that form mountains, how earths contenets formed and separated and continued to change, how seas have opened and closed, and how mountains rise up and then after time are warn down by erosion, how setiment is warn down and then becomes rock again. In science you can see how we use rock as a resource is formed and and how catastrophic events in the past have had dramatic efects on  landscapes we see today, and you can go somewhere where nobodys been before to study whats underground. Its important to learn about earths systems and how they work.

Space is the boundless, three-dimensional extent in which objects and events occur and have relative position and direction. Physical space is often conceived in three lineardimensions, although modern physcists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spcetime. In mathmatics one examines "spaces" with different numbers of dimensions and with different underlying structures. The concept of space is considered to be of fundamental importance to an understanding of the physical universe although disagreement continues between philosphers over whether it is itself an entity, a relationship between entities, or part of a conseptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the timaus  of plato, in his reflections on what the Greeks called khora, or in the Physics of aristotle in the definition of topos, or even in the later "geometrical conception of place" as "spacequa extension" in the Discourse on Place of the 11th century Arab polymath alhazen. Many of these classical philosophical questions were discussed in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. In Issac Newton's view, space was absolute - in the sense that it existed permanently and independently of whether there were any matter in the space
