How Big Is The Earth? Part – III
Now, let’s look at some objects that are so unbelievably large that if they replaced our Sun in our Solar System, they would extend out beyond the orbits of many of the planets. These super-sized stars are billions of times larger than our home planet, and millions of times larger than our Sun.
As you go about your daily life, travel to school, to baseball or dance practice, ride your bike to the park, and look up at the clouds, remember that while Earth seems like a very big place, in reality it is just a tiny rock, a speck in the universe, so small that it cannot be seen unless you are very close to it.
Geography and Geology are the studies of this tiny rock. Geology looks at the processes that formed the Earth, and Geography looks at the Earth’s surface, atmosphere, hydrosphere, biosphere, and at the people who inhabit it.
