Trivia Quiz On Drainage System(Geomorphology)

Streams form a pattern known as a drainage system. A drainage system refers to the network of streams and rivers that drain an area. These streams collect and carry water from higher elevations to lower elevations, eventually leading to larger bodies of water such as lakes or oceans. The pattern formed by streams within a drainage system can vary, with common patterns including dendritic (tree-like), radial (spokes of a wheel), and rectangular (grid-like) patterns, depending on the geological characteristics of the area.

Dendritic drainage is known to pertain to trees. This type of drainage pattern resembles the branching pattern of tree roots, with multiple tributaries joining together to form a main river channel. The term "dendritic" is derived from the Greek word "dendron," meaning tree. Therefore, the correct answer is Dendritic.

A trellis drainage is known for small tributaries feeding into the valleys. This type of drainage pattern resembles a trellis, with main rivers flowing parallel to each other and smaller tributaries joining them at right angles. This pattern is typically formed in areas with alternating layers of resistant and less resistant rock, causing the rivers to follow the lines of weakness and form valleys. The small tributaries then flow into these valleys, creating a trellis-like pattern.

The classification of a drainage system is affected by both topography and geology. Topography refers to the physical features of the land, such as slopes and elevation, which influence the flow of water and the formation of different types of drainage patterns. Geology, on the other hand, refers to the composition and structure of the Earth's crust, including the presence of different types of rocks and soils, which can affect the permeability and water-holding capacity of the land. Therefore, both topography and geology play a significant role in determining the classification of a drainage system.

Volcanoes display radical drainage refers to the fact that volcanic eruptions often result in the release of large amounts of lava, ash, and other volcanic materials. This material flows down the sides of the volcano, creating channels and pathways known as drainage systems. These drainage systems can be quite extensive and can have a significant impact on the surrounding landscape.

Runoff is a type of water flow that occurs when excess water from rain, snowmelt, or irrigation cannot be absorbed by the ground and instead flows over the surface. This water then collects in streams, rivers, or other bodies of water. Runoff is an important process in the water cycle as it helps to replenish water sources and maintain the balance of ecosystems.

Steep slopes cause the formation of a parallel drainage system. This type of drainage pattern occurs when rivers and streams flow parallel to each other down the slope of a mountain or hill. The water follows the path of least resistance, creating parallel channels that are separated by ridges or valleys. This drainage system is common in areas with high relief and is characterized by straight, parallel streams that do not intersect or converge.

A watershed is the correct answer because it refers to the dividing line or boundary that separates one drainage basin from another. It is the high point or ridge where water flows in different directions, determining the boundaries of a drainage basin. Valleys do not divide drainage basins, they are formed within the basin by the flow of water. Holds is not relevant to the division of drainage basins. Therefore, the correct answer is watershed.

The Appalachian mountain is an example of a trellis drainage system. A trellis drainage system is characterized by parallel main rivers with shorter tributaries flowing into them at right angles. The pattern resembles a trellis or ladder-like structure. The Appalachian mountain range in eastern North America exhibits this type of drainage system, with its main rivers flowing parallel to the mountain range and smaller streams joining them at right angles.

The annular drainage system follows a rough circular patch. This means that the drainage pattern forms a circular shape with no specific direction or flow. This type of drainage pattern is commonly found in areas with resistant rock formations or in regions where the underlying geology is composed of concentric layers. The water flow in this system tends to follow the path of least resistance, resulting in a circular pattern of drainage.
