Regions
Geographers study geography. You've probably figured that out by now. But how is this done? The study of the physical space in the world, including its landforms as well as how people interact in this space, is a big project. How do you begin to understand this much space? One way is to start looking for common traits that define certain spaces, allowing you to examine the world in smaller units.
What we're looking at is a region, a unit of geography characterized by some form of shared or uniform traits. Regions can be large or small, depending on the criteria you're using to define them. These units are very helpful ways for us to begin compartmentalizing all that space in the world.
Characteristics of Regions
So, what exactly defines a region? That's an important question, and there are actually a number of ways to answer it. A region is any physical area united by shared characteristics, but there are four main ways we can define this.
Physical Regions
Perhaps most obvious are physical regions, those defined by shared physical characteristics. Physical regions are units of physical space that are very similar in their natural characteristics. For example, the Great Plains are a physical region of North America. Within the larger continent, this section of land is defined by a distinct type of land that's different from the mountains and forested hills around it. Characteristics that define physical regions can include landforms, types of vegetation, climate, or other natural features.
Answer:
The watershed simply restricts the movement of water toward one side, because the water can not move up but only down or on a flat area.
Explanation:
The watersheds represent physical boundaries that are separating the flow of water to rivers, seas, areas, or to put it simply, they direct the movement of water in different directions. The watersheds are marked by landforms that are at a higher elevation than their surroundings, and the separation of the movement of water occurs at the ridges.
Basically, the water moves downward on each side of the ridge. This means that the water on one side of the ridge belongs to one watershed as its waters go in one direction and area, while the water on the other side of the ridge belongs to another watershed because its waters move in another direction and area.
The correct answer is - B. 22 percent.
The economy of the USA nowadays still remains a huge factor and is at the top of the pack, together with China. With little over 1/5 of the world economy they are an economic giant.
On the other side, USA even though still has its position as an economic super power, it must be noticed that it has seen around 50 percent drop in the total world economic participation since the 1960's. This is due to the fact that China has become an economic world power in meantime, as well the rise of some economies that were destroyed after WWII like the German and Japanese economies, which gradually lower the global economic influence of the USA.
