Answer:
Climate is the weather condition of a place over a long period of time.
Weather is the atmospheric condition of a place at a particular period of time which is usually short.
Answer:
When discussing drought, one must have an understanding of aridity and the difference between the two. Aridity is defined, in meteorology and climatology, as "the degree to which a climate lacks effective, life-promoting moisture" (Glossary of Meteorology, American Meteorological Society). Drought is "a period of abnormally dry weather sufficiently long enough to cause a serious hydrological imbalance". Aridity is measured by comparing long-term average water supply (precipitation) to long-term average water demand (evapotranspiration). If demand is greater than supply, on average, then the climate is arid. Drought refers to the moisture balance that happens on a month-to-month (or more frequent) basis. If the water supply is less than water demand for a given month, then that month is abnormally dry; if there is a serious hydrological impact, then a drought is occurring that month. Aridity is permanent, while drought is temporary.
Answer:
B. Heat absorption increases as the albedo decreases
Explanation:
The ice has very high albedo. The reason for this is that it has white coloration, and the light coloration are highly reflective of the sunlight. As the ice melts though, the water surface increases, and the water, unlike the ice, has the capability of absorbing much more heat. With much more water, there will be much more absorption of heat, and since the water has low albedo on only 10, the albedo will decrease on a global level.
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.
