The correct answer is - c. east.
The Appalachian Mountains are located in the eastern part of the United States, and since the Rocky Mountains are in the western part of the country, it puts them east of the Rocky Mountains.
The Appalachians are a very old mountain range, they are dated to about 480 million years ago when they formed during the Ordovician Period. At their peak, these mountains reached heights similar to the Rocky Mountains and the Alps in Europe, but because of the natural erosion they have shrunk and nowadays are much smaller in height.
Answer:
Census
Explanation:
A census is the process of data collection and is the systematic acquisition of data about the given population.
An open lake is a lake where water constantly flows out under almost all climatic circumstances. Because water does not remain in an open lake for any length of time, open lakes are usually fresh water: dissolved solids do not accumulate. Open lakes form in areas where precipitation is greater than evaporation. Because most of the world's water is found in areas of highly effective rainfall, most lakes are open lakes whose water eventually reaches the sea. For instance, the Great Lakes' water flows into the St. Lawrence River and eventually the Atlantic Ocean.
In a closed lake (see endorheic drainage), no water flows out, and water which is not evaporated will remain in a closed lake indefinitely. This means that closed lakes are usually saline, though this salinity varies greatly from around three parts per thousand for most of the Caspian Sea to as much as 400 parts per thousand for the Dead Sea. Only the less salty closed lakes are able to sustain life, and it is completely different from that in rivers or freshwater open lakes. Closed lakes typically form in areas where evaporation is greater than rainfall, although most closed lakes actually obtain their water from a region with much higher precipitation than the area around the lake itself, which is often a depression of some sort.
Hope this helps :)
