Answer:
region is an area that includes a number of places--all of which have something in common. Geographers categorize regions in two basic ways: physical and cultural.
Explanation:
ways: physical and cultural
Answer:
Option (C)
Explanation:
The continental drift hypothesis refers to the large scale, slow motion of continents over the surface of the large ocean basins and it was discovered by Mr. Alfred Wegener. He contributed some evidence regarding this continental drift hypothesis, such as the matching of the continental margins, finding similar fossils in distant continents, finding similar rock types as well as structures present in them. The movement of glaciers and their changing patterns were also observed to prove this theory.
But, of all the given options, one observation does not support the hypothesis, i.e. the lithosphere showing ductile nature in comparison to the brittle rock behavior in the layer of the asthenosphere.
In the brittle zone, the rocks fractures due to the force acting on it, whereas, in the ductile zone, the rocks tend to flow during the time of deformation.
Thus, the correct answer is option (C).
Answer:
Energy of each photon is given by ![0.0335\times 10^{-17}j](https://tex.z-dn.net/?f=0.0335%5Ctimes%2010%5E%7B-17%7Dj)
Explanation:
We have given wavelength of light ![\lambda =590nm=590\times 10^{-9}m](https://tex.z-dn.net/?f=%5Clambda%20%3D590nm%3D590%5Ctimes%2010%5E%7B-9%7Dm)
Speed of light ![c=3\times 10^8m/sec](https://tex.z-dn.net/?f=c%3D3%5Ctimes%2010%5E8m%2Fsec)
Plank's constant ![h=6.6\times 10^{-34}j-s](https://tex.z-dn.net/?f=h%3D6.6%5Ctimes%2010%5E%7B-34%7Dj-s)
We know that energy of photon is given by ![E=h\nu =\frac{hc}{\lambda }](https://tex.z-dn.net/?f=E%3Dh%5Cnu%20%3D%5Cfrac%7Bhc%7D%7B%5Clambda%20%7D)
So energy is given by
Answer:
Rivers of the Coastal Plain were a major means of commercial transportation during the 1700s and early 1800s. Cities founded along the fall line, called “fall line cities,” are located at the places where these rivers crossed the fall line, marking the upstream limit of travel. The city of Columbus, for example, was established where the Chattahoochee River crosses the fall line; Macon, Milledgeville, and Augusta are similarly located at the crossings of the Ocmulgee, Oconee, and Savannah rivers, respectively. These cities became important transportation hubs because traders could only travel upstream until they reached the waterfalls of the fall line. At that point they were forced to disembark and reload their cargo on the other side of the falls in order to continue their journeys. Columbus served as the upstream head of navigation for the Chattahoochee, as did Augusta for the Savannah River and Macon for the Ocmulgee River. After the first steamship arrived in 1828, Columbus became a gateway city for cotton. Above the fall line, flatboats and barges moved goods around the state. Below the fall line, steamships had unimpeded access to move goods, mostly cotton, into the Gulf of Mexico.
The correct answer should be Census
