Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula. With the rise of the sun, the remaining material began to clump together. Part of Hall of the Universe. The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. ... In a similar manner, moons formed orbiting the gas giant planets. Hope this helps!
For climate of a place in order to be simplified and organized and generalized needs to be classified into the understandable forms as accordance to the climatic data obtained for the diverse classification and a compressive view of the climate and a broadly distributed over the earth is represented by the Koppen's climatic classification wee each climate is diverse and given different type of names and numbers.
<u>Such as those of the A (tropical), the B (dry), and the C (temperate), D (continental), and the E (polar). On the basis of the seasonal rainfall and the type of vegetation found in various regions on the earth.</u>
