, scientists believe the universe or in the sky as a whole consists of galaxies in galaxy is usually composed of a spherical comet gas dust. and tend to stay together or separately. Solar system is part of the galaxy. Consists of the Sun, planets, comets, meteorites, lunar dust swirling gas inside the gravity of the sun. The Sun is the center of the system. And the world as a member of one of these systems,
the origin of the solar system
theory of Kant and Harry
sun, planets, moons and other solar system formed from gas to heat and rotating centrifugal force of rotation causes a characteristic ring spread out. central Later, it became the center ring sun. Each ring includes gas and shrink the planet and beyond. The

1. . the crust is the outermost part of the Earth's surface from depths down to about 6-35 km section on the continent, mostly granite. Compounds, silica and alumina is lower. The ocean is mostly Basalt. Which consists of silica, magnesium compound
2. mantle is the layer next to the surface to a thickness of about 3,000 km with various rocks and minerals melt them down into the magma. Due to the very high pressure and temperature of 500-4500 ° C, mainly iron ore, silicon, aluminum, lead to the outside if the magma is called lava that hardens into rock. Igneous rock is a rock, the first
three. Axis or the axis of the Earth is part of a thickness of about 3,440 kilometers from the center consists mostly of iron. There are about 8% nickel, cobalt, and may have some, so it is very dense.
