Dendritic patterns, which are by far the most common, develop in
areas where the rock (or unconsolidated material) beneath the stream has no particular fabric or structure and can be eroded equally easily in all directions
. Examples would be granite, gneiss, volcanic rock, and sedimentary rock that has not been folded.
Where do dendritic drainage patterns form?
A dendritic drainage pattern is the most common form and looks like the branching pattern of tree roots. It
develops in regions underlain by homogeneous material
. That is, the subsurface geology has a similar resistance to weathering so there is no apparent control over the direction the tributaries take.
Where would you expect to find a dendritic drainage pattern quizlet?
it is a fundamental unit of study in hydrology and fluvial geomorphology. A dendritic drainage pattern occurs
when the tributary systems subdivides headway like the limbs of a tree
. These patterns usually form in horizontal sedimentary or in intrusive igneous rocks where the rock mass is reasonably homogeneous.
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.
Which river has dendritic drainage pattern?
In India, if we talk about dendritic drainage patterns, the rivers which follow this system are the
Ganga – Brahmaputra
, the Indus river system, Mahanadi, Godavari, Krishna, etc. These rivers have different tributaries and form a structure that appears like branches of the tree.
What are the 4 types of drainage patterns?
there are 4 types of drainage patterns on the basis of their flowing pattern-
dendritic, trellis, radial and rectangular
.
What do u mean by dendritic drainage pattern?
A drainage pattern in which the streams branch randomly in all directions and at almost any angle
, resembling in plan the branching habit of certain trees. It is produced where a consequent stream receives several tributaries which in turn are fed by smaller tributaries.
When would you see a dendritic drainage pattern?
The main types of drainage patterns:
Dendritic patterns, which are by far the most common,
develop in areas where the rock (or unconsolidated material) beneath the stream has no particular fabric or structure and can be eroded equally easily in all directions
.
Where would you expect to find a radial drainage pattern?
Radial patterns form
around isolated mountains (such as volcanoes) or hills
, and the individual streams typically have dendritic drainage patterns.
What is radial drainage?
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 dendritic pattern work?
Dendritic drainage patterns are most common. They
develop on a land surface where the underlying rock is of uniform resistance to erosion
. Radial drainage patterns develop surrounding areas of high topography where elevation drops from a central high area to surrounding low areas.
How is a dendritic pattern formed?
The dendritic pattern develops
where the river channel follows the slope of the terrain
. The stream with its tributaries resembles the branches of a tree, thus, the name dendritic is given.
What is drainage pattern Class 9?
Trellis Drainage Pattern: When a
river
is joined by its tributaries at almost right angles, it develops a trellis pattern. Trellis pattern develops where hard and soft rocks exist parallel to each other. Rectangular Drainage Pattern: When rocks are strongly joined, then rectangular pattern develops.
What is drainage pattern give example?
A drainage pattern which looks like tree branches with lots of twigs is known as Dendritic drainage pattern. For example, the
rivers of northern plain
. Radial drainage patterns form when rivers originate from a hill and flow in all directions. For example, the rivers originating from the Amarkantak.
What are the different types of drainage pattern?
- Dendritic drainage pattern.
- Parallel drainage pattern.
- Trellis drainage pattern.
- Rectangular drainage pattern.
- Radial drainage pattern.
- Centripetal drainage pattern.
- Deranged drainage pattern.
- Annular drainage pattern.
What is an example of antecedent drainage?
Examples.
Many Himalayan rivers
are good examples of antecedent origin. These rivers originated well before the Himalayan region was uplifted. The rivers Indus, Brahmaputra, Sutlej, Kosi and Subansiri originated on the Tibetan side and now traverse the existing mountain ranges, cutting deep gorges.
