Solar energy (energy released by the sun) has been around for as long as the sun has - an approximate of around 5 million years. In 1861, Angute Mouchout was the first person to convert solar power into energy, when he created a steam engine that ran entirely on solar power. Solar power is one of the only renewable sources on our planet, but is still very inefficient.
In general terms here is how the solar system came into being. An earlier incredibly massive star exploded into a supernova at the end of its life, leaving a huge cloud of gases and debris. Out of this cloud a section began to come together under the force of its own gravity. The gases that formed the sun gathered in the center, and an accretion disk of materials began swirling around it. The accretion disk is material that began falling toward the central mass but fell into a swirling or orbital pattern rather than falling to the center. This disk of gasses and other debris eventually formed the planets. Solar wind rushing out from the young sun pushed the lighter gases away from itself, and this is why the rocky planets are closer in and the gas giants are farther out.
The Sun was formed about 4.57 billion years ago when a hydrogen mhttp://wiki.answers.com/wiki/Molecular_cloud collapsed. When the hydrogen atoms got transformed into helium atoms, heat energy was released and all this resulted in the formation of a massive star; our Sun.
First word: gravity. Second word: time. Gravity acted over time in the midst of gas and dust to pull together small amounts and then increasingly larger amounts of material to form our solar system. It was organized in a way that is nicely explained by our friends at Wikipedia, and a link is provided.
The nebular hypothesis explains how the solar system formed from a giant cloud of gases and dispersed solid particles. It is the most widely-accepted hypothesis that explains how the solar system was formed.
First of all, the term "a cloud of dust and gas", while very accurate, is a gross underestimation of the magnitude of material we are talking about. Imagine if all of the matter that makes up the planets and the sun was to turn to dust. This would be an almost inconceivable amount of dust. The reason it is difficult to understand how the solar system could be formed from dust is because when we think of dust in the conventional sense, we are thinking of small amounts of tiny particles. As these tiny particles coalesced, however, they eventually became much larger particles. As they condensed and combined with each other as they hurled through space, coming into contact with dust and particles all the time, they eventually came to be the solar system that we know today.
About 4.6 billion years ago a supernova had occurred, causing a turbulence to heat up debris compacting into celestial objects know as planets or moons. It had also made protostellar disks making the sun by continuing to flow in debris. The heat was hotter than it was today as the disks used heat from the supernova to power it. The power had stopped flowing when the Sun had erupted to be a main-sequence star. Solar wind from the Sun pushed away all debris left in reach, even though some planets kept some of it as rings.
Solar systems are formed when a large cloud of gas comes together, as a result of its own gravity - and often as a result of some "nudge" from the outside, for example, supernova explosions, or the influence of gravity of other objects. Stars often form in groups this way, so it is quite possible that our solar system escaped from a star cluster.

Scientists believe that lightning is formed when air and ice particles rub against one another in a cloud.
AnswerWhen moisture condenses on small particles in the atmosphere, precipitation is formed. Depending on the chemical make up of the particles, the precipitation can have different effects. When the particles are composed of sulfur compounds, made from the burning of fossil fuels like coal, acid rain is formed and falls on the ecosystems below. Acid rain can drastically change an ecosystem by contaminating forests and freshwater resources.
Steam is formed when the kinetice energy of the particles in boiling water increase and move around so much that they escape and change state. Mist is formed when the air is too cold to hold it's moisture.
In a colloid, particles of one substance are mixed and dispersed with particles of another substance - but they are not dissolved in it. In an paint the pigment is dispersed in the liquid formed from the binding medium and solvent solution. Hope this helps :)

Colloid: A solid which is dispersed amongst a liquid. The solid particles do not settle. Not a solution, because the solid is not dissolved, it is dispersed. Solution: A Mixture of a liquid with a solid dissolved in it. Not a Colloid.
There are two ways that colloids are formed. One is through reduction of larger particles to colloidal size. Another is condensation of smaller particles.
After the rain, small water particles are dispersed in the air. As the sunlight (white light) consists of seven colors, so when it passes through the water droplets, they are split up into there constituents according to the velocities of color. In this way a rainbow is formed.
Atom is formed of electrons, protons and neutrons.
colloid is one of the three primary types of mixtures, with the other two being a solution and suspension. A colloid is a solution that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution. These are also known as colloidal dispersions because the substances remain dispersed and do not settle to the bottom of the container. In colloids, one substance is evenly dispersed in another. The substance being dispersed is referred to as being in the dispersed phase, while the substance in which it is dispersed is in the continuous phase.Properties of ColloidsIn order to be classified as a colloid, the substance in the dispersed phase must be larger than the size of a molecule but smaller than what can be seen with the naked eye. This can be more precisely quantified as one or more of the substance's dimensions must be between 1 and 1000 nanometers. If the dimensions are smaller than this the substance is considered a solution and if they are larger than the substance is a suspension. A common method of classifying colloids is based on the phase of the dispersed substance and what phase it is dispersed in. The types of colloids includes sol, emulsion, foam, and aerosol.Sol is a colloidal suspension with solid particles in a liquid.Emulsion is between two liquids.Foam is formed when many gas particles are trapped in a liquid or solid.Aerosol contains small particles of liquid or solid dispersed in a gas.When the dispersion medium is water, the colloidal system is often referred to as a hydrocolloid. The particles in the dispersed phase can take place in different phases depending on how much water is available. For example, Jello powder mixed in with water creates a hydrocolloid. A common use for hydrocolloids is in the creation of medical dressings.
The rock formed when particles stick together is called Sedimentary Rock. The type of this rock depends on the composition and texture of the particles sticking together.

Sedimentary rocks are probably most vulnerable to weathering because they are formed from cemented (sometimes loosely) particles of other rocks.
