What is rectangular drainage system?
A drainage pattern in which the main streams and their tributaries display many right-angle bends and exhibit sections of approx. the same length; it is indicative of streams following prominent fault or joint systems that break the rocks into rectangular blocks.
What is dendritic pattern in geography?
Dendritic or Pinnate Drainage Pattern This is an irregular tree branch shaped pattern that develops in a terrain which has uniform lithology (uniform rock structure), and where faulting and jointing are insignificant. Examples: Indus, Godavari, Mahanadi, Cauvery, Krishna.
What is radial drainage pattern?
A drainage pattern in which consequent streams radiate or diverge outward, like the spokes of a wheel, from a high central area; it is best developed on the slopes of a young, unbreached domal structure or of a volcanic cone.
How does a centripetal drainage pattern form?
Centripetal drainage pattern is formed when rivers discharge their waters from all directions into a lake or a depression. For example, Loktaklake in Manipur.
What is rectangular drainage pattern in geology?
Rectangular drainage patterns have rivers with right-angle bends. They form where the bedrock is faulted and jointed.
How is rectangular drainage pattern formed?
It is a rectangular pattern formed where two sets of structural controls occurs at right angles. The drainage pattern marked by right-angled bends and right-angled junctions between tributaries and the main stream is known as rectangular drainage.
What is dendritic drainage pattern Class 9?
Drainage Patterns: Dendritic Drainage Pattern: When the river channel follows the slope of the terrain, it develops dendritic pattern. Hence, it is called dendritic pattern. Trellis Drainage Pattern: When a river is joined by its tributaries at almost right angles, it develops a trellis pattern.
What’s dendritic drainage patterns?
It is one of the most common drainage patterns found in the world. It appears like branches of the roots of a tree and happens on that lithographic surface which has a uniform rock structure. Dendrite rock is a kind of crystal that can be found in the regions where a tree-like structure is found. …
What are the different types of drainage patterns?
The patterns formed by the streams, rivers and lakes in a particular drainage basin which are governed by the topography of the land constitute the drainage patterns of an area. There are 7 types of drainage patterns: 1. Dendritic drainage pattern– looks like the branching of a tree, found in regions with homogenous material.
Which is a characteristic of a parallel drainage system?
Parallel drainage system is a pattern of rivers caused by steep slopes with some relief. Because of the steep slopes, the streams are swift and straight, with very few tributaries, and all flow in the same direction. Parallel drainage patterns form where there is a pronounced slope to the surface.
What are the drainage patterns in British Columbia?
Most areas of British Columbia have dendritic patterns, as do most areas of the prairies and the Canadian Shield. Trellis drainage patterns typically develop where sedimentary rocks have been folded or tilted and then eroded to varying degrees depending on their strength.
Where are trellised drainage patterns most likely to be found?
Trellised drainage patterns are generally formed in the regions of cuesta topography where hard beds become escarpments and soft beds are eroded to become valleys or lowlands. Type # 2.
