Drainage Basin B has a
Hey Itu🥺🫧, good to see you again.
2.3.1: The drainage pattern evident in drainage basin A is a deranged drainage pattern.
2.3.2: One characteristic of a deranged drainage pattern is that streams flow in random directions with no clear pattern or main channel. They often include numerous lakes, swamps, and marshes.
2.3.3: The underlying rock structure that influenced the development of the deranged drainage pattern in drainage basin A is typically unconsolidated or disrupted rock material, such as glacial till or volcanic deposits. This creates an irregular surface topography with many depressions, preventing the formation of an organized drainage network and lacking structural control.
2.3.4: • Drainage Basin A has a low drainage density due to its few, widely spaced streams. • Drainage Basin B has a high drainage density due to its many, closely spaced streams. Therefore, Drainage Basin B has a higher drainage density than Drainage Basin A.
2.3.5: Vegetation contributes to a lower drainage density in a drainage basin by: • Intercepting rainfall, which reduces the amount of water reaching the ground as surface runoff. • Increasing infiltration of water into the soil, as plant roots create pathways and organic matter improves soil structure. • Increasing evapotranspiration, returning water to the atmosphere. These processes reduce the volume and velocity of surface runoff, which in turn limits the erosion and formation of new stream channels, leading to a lower overall drainage density.
