The relationship between snowfall amount and glacier size is that higher snowfall amounts lead to larger glaciers.
Answer:
The land was so fertile because of the big amounts of silt that the rivers brought to their shores.
Explanation:
The river valleys of Tigris and Euphrates in the Middle East, and the Nile in Northern Africa, were the places were the two earliest civilizations arose. These two civilizations were Sumer and ancient Egypt. The main reasons why these two civilizations developed were exactly the aforementioned rivers and their valleys.
Tigris and Euphrates on one side, and the Nile on another side, were bringing in enormous amounts of silt to their shores each year. The silt was making the river valleys highly fertile, which in turn meant that the people can engage in large scale agricultural production. Because the people had good conditions for the big production of agricultural goods their food supplies were guaranteed, so they were able to specialize in other fields and gradually develop into real civilizations.
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.
