Why are planets round?

Hi everyone,

I am not sure if any of you have ever asked is question,"Why are planets round?". Well, even if have never asked this question, heres the answer anyway.

ANSWER:

gravity, since it is even on every side of the object, in this case the planets core, there is an equal amount of gravity pulling in mass on all sides which is why the atmosphere is a constant distance from gound even the surface is so unsmooth.


Answer
Gravity is the key. You may be aware that Jupiter, our largest planetary neighbor in the solar system, is almost all gas (there is a small core of non-gaseous material). Understanding that Jupiter is a ball of gas, wouldn't it be bizzare if it had a shape other than a sphere? Think also of a bubble blown by a child (or your inner child) through a loop. Even very large ones (which are the most fun) seem to seek rest in a spherical shape, even if breezes batter and deform it from time to time. Matter seems to seek to balance internal forces. It would be scary to look up at Jupiter and discover that it had morphed into a doughnut shape or a large tube shape.

When we are talking about collections of matter that are planet-sized, the same general idea holds. Taking a mass equal to that of the earth, and of similar materials, you could attempt in your mind to construct a pillar with a 1,000 kilometer diameter. But you wouldn't get too far before the pillar's mass would exert so much gravitational force that the whole thing would come crashing in. Even if you braced the pillar while building it, the inner sections would eventually crumble and/or melt long before you finished. Eventually, all the mass would find its way to balance out the gravitational forces.

HOOT

Hey everyone,

I just watched the movie Hoot and I honestly think it is a nice movie. It is about 3 kids who try to protect some burrowing owls from being buried when someone tries to turn their home into a pancake house. So there you have it, why I even mention this show in my blog. It is connected to the enviroment in a way after all.

Peachick

Hi Everyone!





A few days ago my family and I were at this sales center which had several peacocks and peahens. We were in the car when someone(I forgot who) suddenly said there was a Peachick outside. I look out of the window and there they were, 2 peachicks walking beside their mother. They were so cute! Here's a photo I found to show you how a Peachick looks like. : )

Hey, ummmm changes

Hey everyone,

I know that I had originally planned to changed my blog completely, but I have to stop that. I simply can't think of anything to write. I got another idea, how about I just write about what fascinates me in science? Who knows it might fascinate you too. science is not all about facts and figures you know. It is much more, and trust me, it can be fun. : )

ps: I might also write about other things but they would be involved with science in one way or another. : )

Time to change

Hey,

I realised that no one is actually taking this blog seriously and well I guess that is my fault. My intended viewers have as far as I know, never came across this blog and my friends who know about this blog are not interested in science and the environment as much as I am and thus are doing nothing. I am going to change this blog, I am going to make it serious, though I wonder how much can I change the world with 1 simple blog. Maybe I should start a website, but I must be unique and different. If I approach people with the same ideas and the same method of persuasion as the previous generations nothing will change. There will be sympathy and maybe a little work done, but it would be just the same as before. So I must do things differently, I must.
