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.

Space has its own geography as history happens in time
Corporations are often accused of despoiling the environment in their quest for profit. Free enterprise is supposedly incompatible with environmental preservation so that government regulation is required.
Such thinking is the basis for current proposals to expand environmental regulation greatly. So many new controls have been proposed and enacted that the late economic journalist Warren Brookes once forecast that the U.S. Environmental Protection Agency (EPA) could well become "the most powerful government agency on earth, involved in massive levels of economic, social, scientific, and political spending and interference.
But if the profit motive is the primary cause of pollution, one would not expect to find much pollution in socialist countries, such as the former Soviet Union, China, and in the former Communist countries of Eastern and Central Europe. That is, in theory. In reality, exactly the opposite is true: The socialist world suffers from the worst pollution on earth. Could it be that free enterprise is not so incompatible with environmental protection after all?
Answer: He found a rock, and the crystals inside are minerals.
Options:
- He found a rock, and the crystals inside are minerals.
-
He found a mineral, and the crystals inside are rocks.
- He found a rock, and the crystals inside are rocks, too.
-
He found a mineral, and the crystals inside are made of dirt.
Explanation:
A rock differs from a mineral. While they are both solid, a mineral has a crystalline structure while a rock does not have a specific structure. Rocks are made up of different mineral structures and that is what Joseph discovered on dropping the rock, one of the component minerals in the rock. For example, a type of rock, slate may consist of feldspar, quartz among many other minerals.
