The waterways and mountains
of the United States, much like the rest of the world, have had a significant
impact on where people settled and how towns and cities interacted with one
another. Large mountain ranges served as natural barriers between groups,
causing distinct regional shared cultures to develop due to the relative
isolation and shared geography that mountain ranges create. The opposite is
true for rivers, which connected communities through ease of travel, trade, and
shared access to water and other natural resources.
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 :)
An earthquake triggered the waves, so the energy came from the earthquake. The earthquake’s energy comes from the tectonic plates movements.
