Often asked: Which Of The Following Features Are Generally Not Associated With Mountain Streams And Rivers?

Which of the following influences whether a flood occurs?

Rainfall is the most important factor in creating a flood Put simply, floods occur when the amount of water flowing from a catchment exceeds the capacity of its drains, creeks and rivers.

Which of the following is the main reason that a delta forms when a stream flows into a lake or sea?

Deltas form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river.

Which of the following features is common in a meandering stream system?

Which of the following features characterize meandering streams? They have channels that are very curved, commonly forming tight loops.

What are the 5 types of floods?

Flood types

  • Flash floods.
  • Coastal floods.
  • Urban floods.
  • River (or fluvial) floods.
  • Ponding (or pluvial flooding)

What are the 2 types of floods?

There are two basic types of floods: flash floods and the more widespread river floods. Flash floods generally cause greater loss of life and river floods generally cause greater loss of property.

What are the 3 types of deltas?

The three main types of deltas are the arcuate, the bird’s foot and the cuspate.

What is called Delta?

A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.

What is Cuspate Delta?

Answer: Cuspate deltas (e.g. Ebro Delta, Spain) are vaguely shaped like a V with curved sides. Cuspate deltas form when a river flows into a sea with waves that hit it head on, spreading the deposited sediment out. The Tiber River forms a cuspate delta as it empties into the Tyrrhenian Sea near Rome, Italy.

What are two components of a river’s flow?

“Flow” refers to the water running in a river or stream. There are two important aspects to a river’s natural flow. First, there is the amount of water that flows in the river. Some rivers get enough water from their headwaters, tributaries, and rain to flow all year round.

What are the main features of a meander?

Meanders

  • As the river erodes laterally, to the right side then the left side, it forms large bends, and then horseshoe-like loops called meanders.
  • The formation of meanders is due to both deposition and erosion and meanders gradually migrate downstream.

How oxbow lake is formed?

Oxbow lake, small lake located in an abandoned meander loop of a river channel. It is generally formed as a river cuts through a meander neck to shorten its course, causes the old channel to be rapidly blocked off, and then migrates away from the lake.

What is a drainage divide quizlet?

drainage divide. extensive mountain and highland regions separating drainage basins, sending flows in to the major bodies of water. watershed. a large area where all of the water that is under or on it drains in to the same place. fluvial.

What is a point bar quizlet?

point bar. the inside of a meander; lowest velocity, so deposition. cut bank. the outside of a meander; highest velocity, so erosion. oxbow lake.

What does the hydrologic cycle reference quizlet?

The water cycle, also known as the hydrologic cycle or the H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmos…
