Ancient civilizations grew around river valleys because the land around river valleys was lush and fertile, allowing effective systems for growing crops. Also helping with the crop growth, the rivers would naturally flood just enough to keep the soil properly moist. The rivers also served as a sure-fire and efficient way to trade with other civilizations. Because of these factors of land and trade, many ancient civilizations sprung up around river valleys.
Answer:
Convection currents flow due to variations in the temperature and salinity in seawater, both of which influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.
The formula for area can be written as follows:
area = length x width
Substitute the known values into this formula. In this case, we’ll start with the first flag:
42 = 6 x (length)
Then, divide 6 from both sides:
42/6 = length
7 = length
The length of the first flag is 7 feet. Now, we’ll move on to the second flag. Substitute:
48 = 6 x (length)
Divide 6 from both sides:
48/6 = length
8 = length
The length of the second flag is 8 feet.
Hope this helps!
