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!
Answer:
b. There is insufficient contrast in surface type (land vs. ocean) in the middle latitudes.
Explanation:
The sources of air masses can be produced or at very high latitudes because they can carry big amounts of air from the top of a mountain till the bottom by the differences of pressure and temperatures. This kind of air mass is called continental.
In the other hand, in a low latitude, the air coming from the sea, try to reach higher latitudes, again, by pressure and temperatures differences. These kind of air masses are called maritime.
