The six crystal forms are cubic, tetragonal, hexagonal, orthorhombic, monoclinic, and triclinic. A purple flourite specimen is an cubic formed mineral. Zircon is an form of tetragonal mineral. A beryl is an example of an hexagonal mineral. An adimite is an example of an monoclinic mineral. A azurite is an example of an monoclinic mineral. A boleite is an example of a triclinic mineral. MIinerals come in all diffrent shapes, colors, and sizes.

The best renewable energy source is solar energy. Solar energy takes the light from the sun and turns it into energy. The equipment is very expensive but it pays off in the end. In some place you can do net marketing and pay very little if you use electric through your energy company. Net marketing is calculated by how much energy that you used of the energy company and how much you gave to the energy company. For example if your mom is at work and you and your sister at school and no ones home your energy will be put into the power lines of your neighborhood.

Like all resources available solar power has its downfalls. Besides it being very expensive at first, you cannot use it when the sun is not out or cloudy days when the sun doesn't shine alot. In places where they don't get alot of sunshine this may not be a good resource for them.

I think that in a few years there will be a way to store the electricity in some sort of battery that charges during the day and powers on at night.

My favorite map projection depends on what i need the map for. If I had to just choose a map I would pick the gnomic map. By placeing a piece of paper on a globe so that it touches a single point on the globes surface. This map can show the distance between places, even though the distances are a little off it can help people such as sailors, navigators, and travelers. It can easily show how far the one point is from another.

Keresa's Earth Science Fave

Earth science is the study of geology. My favorite subdivision of the subject is astronomy. Astronomy intrest me because it could better help me understand my planet as well as others. Knowing the physical laws of my enviroment could help me take care of it, knowing what it needs, how to take care of it, how it revolves around the sun and how to tell time by observing the sun.
Astronomy can also help me learn about earths surrounding neighbors and their make up. It can help me compare the planets and see whats diffrent. Knowing about this kind of information can help me try to discover things such as establishing life on another planet. This is a very intresting subject.
