A valley is a pure dip within the floor. Valleys run by means of hills, mountains, and flat areas of land referred to as plains. Valleys are discovered on the ocean flooring, too. Some valleys are slender, and a few are extensive. Rivers and streams typically movement by way of valleys. Many valleys have good soil for farmland.
Most valleys type when the operating water of a river wears away the earth alongside its banks. A slowly shifting sheet of ice referred to as a glacier <<GLAY shuhr>> can scrape out a U-formed valley in mountains. A rift valley might type when a part of Earth’s crust sinks.
