What are the 4 types of drainage patterns?
Drainage patterns
- Dendritic drainage pattern.
- Parallel drainage pattern.
- Trellis drainage pattern.
- Rectangular drainage pattern.
- Radial drainage pattern.
- Centripetal drainage pattern.
- Deranged drainage pattern.
- Annular drainage pattern.
Which is the largest river basin in the world?
Amazon Basin
Is Phoenix a valley or a basin?
phoenix is technically in a valley. The valley runs northeast to southwest. A basin, on the other hand, refers to a section of land which is lower than the surrounding areas. Most commonly, this means a depression.
What is the difference between basin and catchment?
But, there are subtle differences between them. River Basin: All the area drained by a river and its tributaries. Catchment area: It refers to all the area of land over which rain falls and is caught to serve a river basin. There are many smaller watersheds within a river basin.
What do basins and valleys have in common?
Tectonic basins and rift valleys, landforms characterized by relatively steep, mountainous sides and flat floors. The steep sides are created by displacement on faults such that the valley floor moves down relative to the surrounding margins, or, conversely, the margins move up relative to the floor.
Do rift valleys form mountains?
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift. On Earth, rifts can occur at all elevations, from the sea floor to plateaus and mountain ranges in continental crust or in oceanic crust.
Why do rift valleys have steep sides?
c) Rift valleys have steep sides because they are formed when the earth crust is divided, they are not like those valley which are formed by soil erosion.
What name is given to the steep sides of a rift valley?
Rift valleys are sometimes called grabens and the steep sides called horsts. The area where the tectonic plates are pulling apart is known as a divergent boundary.
Which is the longest rift valley in the world?
List
| World | Rift/Valley | Length |
|---|---|---|
| Earth | Great Rift Valley | 6,000 km (3,700 mi) |
| Canadian Arctic Rift System | 4,800 km (3,000 mi) | |
| West Antarctic Rift System | ||
| Midcontinent Rift System | 2,000 km (1,200 mi) |
Is a rift valley convergent or divergent?
Areas where plates are colliding form convergent boundaries, and areas where plates are expanding create divergent boundaries. Rift valleys are formed by divergent boundaries that involve continental plates.
Which location is on a major rift valley?
The Rio Grande Rift stretches from central Colorado to the Mexican state of Chihuahua. The most well-known rift valley on Earth is probably the so-called “Great Rift Valley System” which stretches from the Middle East in the north to Mozambique in the south.
In which two countries is the Great Rift Valley?
In Kenya, Uganda and the fringes of South Sudan, the Great Rift runs along two separate branches that are joined to each other only at their southern end, in Southern Tanzania along its border with Zambia. The two branches are called the Western Rift Valley and the Eastern Rift Valley.
What will eventually happen if a Rift Valley continues to pull apart?
If these two rift zones continue they will break apart the crustal plates they are located on and will create new plates. Sea water will flood the rift valleys and they will eventually become seas like the Red Sea.
